Lightpath to deploy 800Gb/sec links using Ciena’s WaveLogic 5 Extreme technology

Fiber-optic network services provider Lightpath has rolled out 800-Gbps capabilities via implementation of Ciena’s WaveLogic 5 Extreme technology. The company also will deploy Ciena’s Waveserver Ai platform, which will pair with a flexible-grid optical transport network based on Ciena’s 6500 RLS platforms.

The Lightpath Network consists of over 18,000 route miles of fiber providing connectivity to over 12,000 service locations.  Lightpath provides a variety of connectivity and business services to customers in the metro New York area, including financial services firms (e.g. “Lightpath intros 100-Gbps optical transport service” and “Lightpath raises New York metro fiber-optic network footprint”).  Using Ciena’s coherent optical solution, Lightpath’s network becomes more adaptive, allowing it to respond quickly to ever-changing bandwidth demands while maximizing operational efficiencies, providing customers with more reliable, high-speed services.

The enhanced optical transport technology will increase fiber network flexibility and efficiency as well as support Physical Layer encryption for data security. Cable MSO Altice USA owns a controlling interest in the company (see “Altice USA to sell almost 50% of Lightpath fiber enterprise business to Morgan Stanley Infrastructure Partners”).

“In order for our customers to execute on their own digital innovations, we need to provide them with fast and reliable connectivity. With Ciena’s solutions, our customers in the New York and Boston metro areas will now experience next-level digital services with high bandwidth and minimal latency,” commented Phil Olivero, CTO at Lightpath.

“As users consume more digital content, it is crucial for service providers to ensure their network can adapt to these surging and often unpredictable demands. With Ciena’s technology, Lightpath is adding scalability to meet bandwidth demands and also gaining real-time visibility into the performance of its network,” added Kevin Sheehan, CTO, Americas, for Ciena.

WaveLogic 5 Extreme is now available in three different product implementations to meet network architecture preferences: 6500 Packet-Optical PlatformWaveserver 5 compact interconnect platform, and the WaveLogic 5 Extreme 800G transceiver module

The WaveLogic 5 Extreme chip is 12mm x 16mm CMOS device. Here are some of its remarkable features:

  • It is the industry’s first commercial 7nm CMOS device for optical networks.
  • Based on 7nm FinFET technology, it includes 3km of wiring and contains 800 Trillion operations per second, which is about as much horsepower as 400,000 laptops!

Facebook and Liquid Intelligent Technologies to build huge fiber network in Africa

Facebook Inc. and Africa’s largest fiber optics company, Liquid Intelligent Technologies, are extending their reach on the continent by laying 2,000 kilometers (1,243 miles) of fiber in the Democratic Republic of Congo.  The two companies intend to build an extensive long haul and metro fiber network.  Apparently, this is part of Facebook’s effort to “connect the unconnected,” especially in 3rd world countries.

The move will make Facebook one of the biggest investors in fiber networks in the region. The cable will eventually extend the reach of 2Africa, a major sub-sea line that’s also been co-developed by Facebook, the two companies said in a July 5th statement.

Facebook will invest in the fiber build and support network planning. Liquid Technologies will own, build and operate the fiber network, and provide wholesale services to mobile network operators and internet service providers. The network will help create a digital corridor from the Atlantic Ocean through the Congo Rainforest, the second largest rainforest after the Amazon, to East Africa, and onto the Indian Ocean. Liquid Technologies has been working on the digital corridor for more than two years, which now reaches Central DRC. This corridor will connect DRC to its neighboring countries including Angola, Congo Brazzaville, Rwanda, Tanzania, Uganda, and Zambia.

The new build will stretch from Central DRC to the Eastern border with Rwanda and extend the reach of 2Africa, a major undersea cable that will land along both the East and West African coasts, and better connect Africa to the Middle East and Europe. Additionally, Liquid will employ more than 5,000 people from local communities to build the fiber network.

“This is one of the most difficult fiber builds ever undertaken, crossing more than 2,000 kilometers of some of the most challenging terrain in the world” said Nic Rudnick, Group CEO of Liquid Intelligent Technologies. “Liquid Technologies and Facebook have a common mission to provide affordable infrastructure to bridge connectivity gaps, and we believe our work together will have a tremendous impact on internet accessibility across the region.”

Liquid Intelligent Technologies is present in more than 20 countries in Africa, with a vision of a digitally connected future that leaves no African behind.

“This fiber build with Liquid Technologies is one of the most exciting projects we have worked on,” said Ibrahima Ba, Director of Network Investments, Emerging Markets at Facebook. “We know that deploying fibre in this region is not easy, but it is a crucial part of extending broadband access to under-connected areas. We look forward to seeing how our fibre build will help increase the availability and improve the affordability of high-quality internet in DRC.”

Facebook has been striving to improve connectivity in Africa to take advantage of a young population and the increasing availability and affordability of smartphones. The social-media giant switched to a predominantly fiber strategy following the failed launch of a satellite to beam signal around the continent in 2016.

About Liquid Intelligent Technologies:
Liquid Intelligent Technologies is a pan-African technology group present in more than 20 countries, mainly in Sub-Saharan Africa. Liquid has firmly established itself as the leading provider of pan-African digital infrastructure with an extensive network covering over 100,000 km. Liquid Intelligent Technologies is redefining network, cloud, and cybersecurity offerings through strategic partnerships with leading global players, innovative business applications, smart cloud services and world-class security on the African continent. Liquid Intelligent Technologies is now a comprehensive, one-stop technology group that provides customized digital solutions to public and private sector companies across the continent under several business units including Liquid Networks, Liquid Cloud and CyberSecurity and Africa Data Centers.

Will AT&T’s huge fiber build-out win broadband market share from cablecos/MSOs?

AT&T added 235,000 fiber connections in the first quarter, ending the period with nearly 5.2 million total fiber customers. AT&T says they have a total of around 15 million fiber and non-fiber customers, so fiber access is approximately 1/3 of total customers now.

The company recently announced it plans to build fiber to 3 million new customer locations this year and 4 million next year. AT&T plans to double the number of locations where it offers fiber Internet, from approximately 15 million to about 30 million, by 2025. To do that, AT&T is planning to increase its annual capital expenses from $21 billion to around $24 billion.

AT&T’s new focus on connectivity over content is a direct result of its spinning off Warner Media to Discovery, as we chronicled in this IEEE Techblog post. Thaddeus Arroyo, head of AT&T’s consumer business, made that crystal clear at a recent BoA investor event:

“We expect capital expenditures of about $24 billion a year after the Warner Media discovery transaction closes. That’s an incremental investment that’s going to go to fiber to 5G capacity and 5G C-band deployment.

We have another great opportunity, the one we continue to talk around fiber. So as part of this capital, we’re going to be investing in fiber expansion to meet the growing needs for bandwidth that require a much more robust fiber network regardless of the last mile serving technology. Fiber is the foundation that fuels our network. Expanding our fiber reach serves multiple services hanging off at each strand of fiber. It includes macro cell sites, small cell sites, wholesale services, enterprise, small business, and fiber that’s extended directly into our customers’ homes and into businesses.

We plan to reach 30 million customer locations passed with fiber by the end of 2025. That’s going to double our existing fiber footprint. And investing in fiber drives solid returns because it’s a superior product. Where we have fiber we win, we’re improving share in our fiber footprint, and the penetration rates are accelerating and growing, given our increased financial flexibility. We’re comfortable in our ability to invest and achieve our leverage targets that we outlined of getting to 2.6% at close and below 2.5% by the end of 2023.”

Mo Katibeh, the AT&T executive responsible for fiber and 5G build-outs, added on via a recent post on LinkedIn:  “We are building MORE Fiber to MORE homes and businesses. And we’re talking A LOT of fiber – MILLIONS of new locations every year, planning to cover 30 MILLION customer locations by the end of 2025! And you know what comes with all that investment in America? JOBS. Our AT&T Network Build team is GROWING..”

Previously, Katibeh wrote on LinkedIn : “Contributing to a large portion of the $105B Capital spend between 2016 and 2020 – our team is building out AT&T #Fiber to MILLIONS of new customer locations in 2021, as well as augmenting America’s best mobility network with more capacity, more speed – and more #5G (you know I love 5G!).”

…………………………………………………………………………………………………………………………………………………………..

So with all that said, will AT&T’s fiber build-out keep pace with cable companies/MSOs DOCSIS networks?

Tom Rutledge, Charter’s CEO, made a brief comment about plant upgrades on the earnings call (note – Dave Watson made similar comments on the Comcast earnings call):

“We’re continuously increasing the capacity in our core and hubs and augmenting our network to improve speed and performance at a pace dictated by customers in the marketplace. We have a cost-effective approach to using DOCSIS 3.1, which we’ve already deployed, to expand our network capacity 1.2 gigahertz, which gives us the ability to offer multi-gigabit speeds in the downstream and at least 1 gigabit per second in the upstream.”

According to Leichtman Research Group, the top cable companies had 68 million broadband subscribers, and top wireline telecom companies had 33.2 million subscribers at the end of 2019.

“Based on the currently available information, cable stole wired broadband market share in Verizon and AT&T markets as well. Oy vey!” said Jim Patterson of Patterson Advisory Group in his May 2, 2021 newsletter.  “Think about Comcast and AT&T as having roughly the same number of homes passed (AT&T probably closer to 57 million homes versus the nearly 60 million shown for Comcast),” he added.  Patterson noted that top cable companies Comcast, Charter and Altice managed to capture 86% of broadband customer growth in the U.S. in the first quarter of this year.

“(AT&T) fiber connections simply aren’t growing fast enough to keep up,” wrote colleague Craig Moffett of MoffettNathanson in a recent note to clients.  Here’s more:

To be sure, there are questions about the extent to which these deployments will overlap cable (or will instead be focused on unserved rural communities), and the extent to which labor and supply chain contraints might limit acheivability of announced targets. Still, taken together, these deployments suggest that, after a precipitous decline in new fiber construction in 2020, planned fiber deployments do, indeed, rise over the next two years; we expect that both 2021 and 2022 will represent new all-time peaks in total number of fiber homes passed. Typically, the competitive impact from overbuilds is felt with some lag, suggesting the impact on cable operators will peak in 2024/2025.

At the same time, we expect that federal stimulus to accelerate broadband market growth in 2021 and 2022, perhaps significantly, with new household formation, in particular, driving upside to 2021 and 2022 forecasts.

Longer term, however, Cable operators will have to contend with more fiber overbuilds, as TelCos increasingly see both more favorable economics for fiber deployment and increasingly acknowledge that their copper plant faces imminent obsolescence without it. The forecasts for fiber deployment in this note suggest that 2021 will be a record for fiber construction – assuming labor and materials capacity can accommodate the TelCos’ own forecasts – and 2022 will step up higher still. After that, deployments are expected to abate, at least to a degree.

“Cable can upgrade its plant quickly and at low cost to offer at least 4.6Gbit/s down and 1.5Gbit/s up, well beyond current fiber offerings. They can do this before the move to DOCSIS 4.0, which is still years off,” wrote the financial analysts at New Street Research in a recent note to investors.   The result, according to the New Street analysts, is that fiber providers like AT&T won’t necessarily be able to dominate the fiber market with a 1 Gbit/s FTTH/FTTP connection and take market share from cable incumbents.

“Cable will face new fiber competition in more of its markets over the next few years; however, there is little to no prospect of fiber delivering a service in those markets that cable can’t easily match or beat,” New Street concluded.

…………………………………………………………………………………………………………………………………………………………….

“Looking back and being a little critical, we probably allowed the cable companies to execute and to take share in that market in a significant way,” AT&T CFO Pascal Desroches said at a recent Credit Suisse investor event.

AT&T executives have said that the company’s fiber investment ultimately will generate internal returns of around 15%. Desroches said that return on investment will be due to a variety of factors. Fiber “supports not only consumer needs, it supports needs for our enterprise businesses as well as needs for potentially our reseller business. So being able to look across and integrate the planning for fiber deployment such that it not only serves consumer needs, but it serves these other market adjacencies as well is something that we haven’t been very good at historically, That’s why we’re really bullish and we believe we’re going to be able to execute really well here,” AT&T’s CFO concluded.

Ciena demo’s 45 wavelengths @400G; Joins Google’s Cloud’s 5G/Edge ISV Program

During OFC 2021 last week, Ciena and Lumenisity Ltd.  said that they had partnered to demonstrate transmission of 45 wavelengths, each at 400G, over 1,000 km of hollowcore fiber cable.

The demonstration paired Lumenisity’s CoreSmart hollowcore cable with Ciena’s WaveLogic 5 Extreme and Nano coherent optical engines, with the transmission occurring in a recirculating loop. The companies say their work indicates that hollowcore fiber cable can be used for high-bandwidth, long-reach applications such as data center interconnect (DCI) in addition to edge and 5G xHaul applications Lumenisity had previously cited (see Lumenisity, BT drive 400ZR DWDM transmission over hollowcore fiber and BT testing hollowcore fiber for 5G support).

Lumenisty said that it has been working over the past six months with ecosystem partners to test the CoreSmart low-latency hollowcore cable in its System Lab in Romsey, UK (see Startup Lumenisity unveils hollowcore fiber cables for DWDM applications, new funding” for more on Lumenisity’s fiber). Ciena participated in at least some of those exercises, including a second trial in which the two companies achieved a capacity of 38.4 Tbps with 48x800G channels over greater than 20 km without in line amplification using the current generation of CoreSmart. Lumenisity says the next generation of CoreSmart will be able to extend reach in such an application to between 50-100 km with no inline amplification when paired with the WaveLogic 5 Extreme.

“The results obtained both internally and with Ciena commercial WaveLogic 5 systems show further evidence that we are bringing our world-class hollowcore fiber cable technology to market at an accelerating rate for multiple high-capacity applications, that solve real world latency issues for our customers,” commented Tony Pearson, business development director at Lumenisity.

“System characterization results of WaveLogic 5 Extreme programmable 800G and WaveLogic 5 Nano 400ZR coherent pluggables running over CoreSmart show promising results with hollowcore fiber now proven to preserve high-capacity while materially reducing latency,” added Steve Alexander, senior vice president and CTO of Ciena. “We are proud to be at the forefront of this breakthrough technological achievement where we can enable a 50% increase in reach for latency-sensitive data center interconnects.”

…………………………………………………………………………………………………………………………………….

Separately, CTO Alexander wrote a blog titled, “Ciena has joined Google Cloud’s 5G/Edge ISV Program to help enterprises accelerate migration of their IT resources to the cloud

Here’s an excerpt:

To facilitate the migration of enterprise IT workloads to the cloud, there is a requirement for higher speed connections from the enterprise edge to cloud provider that are scalable with enhanced security to best protect critical business data. Shared IP network connections to the cloud are acceptable for lower speed (10Gb/s) connections and below. However, when secure, higher speed connections are required to the cloud, connectivity via the IP network can become overly complex, expensive, and inefficient when compared to the optical network (Optical Fast Lane) that can provide a more efficient, cost-effective, and secure option for enterprises needing to reduce their workload migration times to support their evolving business objectives.

For the multi-cloud market to succeed, it must reduce the friction for enterprises to migrate their workloads to a cloud provider, as well as between cloud providers – on demand. This is analogous to the days when you had a mobile plan with one carrier, and to switch to another carrier, you had to switch mobile numbers, which was too complex for most customers, so they stuck with their existing carrier. Only when consumers could keep their phone number when they switched carriers (through Local Number Portability), did it make the mobile market truly competitive leading to improved choice, pricing, and innovation. This is what we’re trying to achieve in the multi-cloud market.

Google Cloud is one of the leading cloud providers in the market that embraces an architecture that enables their enterprise customers to gracefully migrate their workloads to Google Cloud via an Optical Fast Lane that enables Enterprise to develop and leverage the Google Cloud for new and innovative applications. Ciena is excited to be a key player in this program and in addressing this opportunity in the industry. This builds off Ciena’s long standing relationship with Google and other Cloud Providers serving both private and managed high-capacity optical transport networks – principally dominated by subsea, long-haul, metro and DCI connectivity.

Ciena is also a major supplier to Communication Service Providers (CSPs) and MSOs – serving all segments of the network – including high-speed access connectivity for Enterprises as well as cell-site routing and backhaul. In partnership with CSPs, Google Cloud is helping customers leverage their edge real-estate assets to facilitate low latency connectivity to Google Cloud and reduce the friction required for enterprises to improve their mean time to the cloud for their data and workloads.

2021 Optical Fiber Conference (OFC) Highlights and Links to Videos

The premier event in optical telecom—the 2021 Optical Fiber Communication Conference and Exhibition (OFC) concluded last week. The virtual event drew over 6,500 registrants from 83 countries.

“OFC 2021 saw technology announcements and technical presentations spanning the optical communications ecosystem, including advancements in optoelectronic devices, packaging and digital signal processing that are all rapidly evolving to achieve 800G and beyond, as well as those in architectures and algorithms towards more intelligent optical networking,” said Jun-ichi Kani, OFC General Chair, NTT, Japan. “OFC is the only event where attendees can access the full spectrum of trends shaping the industry and the way we connect across the globe.”

Speakers presented breakthroughs in many areas, including 400/ZR+, 800G, co-packaged optics, embedded optics, next-gen optical access, silicon photonics, space-division multiplexing, data center networks, automation and intelligence in networks and more. Sessions on quantum science and technologies, sensor applications and free space optics appealed to a large audience and enriched the OFC experience. Recorded sessions are available to registrants as on-demand content for 60 days following the close of the event.

“OFC is the go-to event for the optics industry,” said Jimmy Yu, vice president, Dell’Oro Group. “From the thought-provoking panel discussions to the product announcements, OFC has always been the place where I learn about emerging technologies.”

Technology experts from global leaders II-VI, Broadcom, Ciena, Cisco, Corning, Innolight, Intel, Juniper Networks, Lumentum, NeoPhotonics, Nokia and Ribbon discussed developments in hardware and software-based networking solutions in daily briefings with leading analysts, Sterling Perrin, Heavy Reading; Ian Redpath, OMDIA; Andrew Schmitt, Cignal AI; Jimmy Yu, Dell’Oro Group and Vladimir Kozlov, LightCounting. The videos can be viewed here.

The TIP sub-group said multi-vendor integration and services operations “were achieved through open standard models and APIs supported by the Optical SDN Controller, including Transport-API, OpenConfig and Open REST.”

“This proof of concept is an important milestone in the journey to fully open and disaggregated optical networking. It offers new levels of visibility and a way to manage the entire multi-vendor environment,” commented Christoph Glingener, CTO at ADVA.

Technology Showcases from 3M, AIM Photonics, Corning, EFFECT Photonics, Infinera, Jabil, Juniper Networks, Keysight Technologies, Lumentum, Luna Innovations, Murata, Nokia, Pi, Renesas, Ribbon, Samtec, Sicoya, Synopsys, Tektronix, Telescent and Xilinx gave deep dives into their cutting-edge products.

OFC 2021 exhibitor news announcements are posted to the OFC Newsroom.

Innovations in Optics
Leading researchers from around the world presented technical peer-reviewed papers, including:

Post Deadline Papers looked to the future with developments in high-speed individual LEDs, modulated lasers, record low loss in hollow core fibers for applications in power delivery and sensing and other topic areas important to industry.

Analysts also revealed their recent findings around the sector to coincide with the event. For instance, Cignal AI suggested there have been strong gains in switching and routing spending by operators in the first quarter of the year, but these were offset by the slightly weaker deployment of optical transport gear.

Scott Wilkinson, lead analyst for transport hardware at Cignal AI, noted that “Chinese spending on optical hardware has plateaued as major 5G network builds mature and new projects have not been initiated.”  He added that the country’s “extraordinary growth during 2015 to 2018 could not continue long term due to the impracticality of expanding upon the enormous amounts that had been spent in the region.”

In general, analysts reported subdued activity by Chinese operators across all product categories after last year’s strong growth, while most other territories showed a rebound this quarter.

Mobile Optical Pluggables (MOPA) Technical Whitepaper

Nokia, Ericsson, II-VI, Lumentum and Sumitomo Electric published a joint technical paper making the case for reducing the wide choice of Mobile Optical Pluggables (MOPA) used to connect cell sites to fiber optic networks. The co-authors of the paper have recommended predefined optical blueprints that help operators speed up time to market using a common list of optical pluggable modules in a market worth $500 million per year.

Optical pluggables are defined as front-panel pluggable optical transceivers in popular form factors like SFP+, SFP28, QSFP28, etc. and the Blueprints are intended as global solutions, i.e., as generic as possible to cover a wide range of network scenarios.

The first-time joint industry initiative, published in time for the Optical Networking and Communication Conference & Exhibition, lays out a set of Mobile Optical Blueprints which describe the most optimized optical pluggable modules and passive optical components. Recommendations include optical characteristics such as data rates, reach, power, wavelengths as well as mechanical characteristics such as form factor, heat dissipation and operational temperature.

Ian Redpath, Practice Leader, Transport Networks and Components at Omdia said:  “In a 5G world, optical pluggables will be utilized to connect cell sites to the network core. Network operators are currently challenged with assessing many pluggable variations, increasing their qualification work load and slowing time to deploy. MOPA will streamline efforts for the connectivity community, enabling cost reductions and reducing time to deploy.”

Stefaan Vanhastel, CTO Nokia Fixed Networks said: “Fiber is a critical component of 5G rollouts and provides unmatched capacity for 5G transport. A clear overview of available optics strategies makes it easier to design and deploy 5G networks. We are pleased to be joining forces with Ericsson, II-VI, Lumentum and Sumitomo Electric on this vital initiative which will make the choice for fiber even more compelling in the transport domain.”

Mobile Optical Pluggables (MOPA) Technical Paper, June 8, 2021
 

NeoPhotonics CFP2-DCO Module Transmission of 400Gbps over 1500 km

Optical components maker NeoPhotonics said it was able to transmit data at 400 Gbps over a distance of 1500 km, using its Multi-Rate CFP2-DCO coherent pluggable transceivers, in a 75 GHz-spaced DWDM network.

The demonstration was done in NeoPhotonics Transmission System Testbed using production modules with enhanced firmware and 19 in-line erbium-doped fiber amplifiers (EDFA).

To achieve 1,500 km reach and a 400G data rate, the modules were operated at 69 Gbaud using 16 QAM modulation. NeoPhotonics added that the modules each consumed considerably less electrical power than line card systems operating at comparable data rates and distances. These 400G CFP2-DCO coherent pluggable transceiver modules use NeoPhotonics Indium Phosphide-based coherent components, along with its ultra-narrow linewidth tunable laser. These components include Class 40 CDM, Class 40 Micro-ICR and Nano-ITLA.

These 400G CFP2-DCO coherent pluggable transceiver modules use NeoPhotonics high performance Indium Phosphide-based coherent components, along with its ultra-narrow linewidth tunable laser. These components are all shipping in high volume into multiple coherent system applications, and include:

  • Class 40 CDM: NeoPhotonics Class 40, polarization multiplexed, quadrature coherent driver modulator (CDM) features a co-packaged InP modulator with a linear, high bandwidth, differential driver, and is designed for low V-Pi, low insertion loss and a high extinction ratio. The compact package is designed to be compliant with the form factor of the OIF Implementation Agreement #OIF-HB-CDM-01.0.
  • Class 40 Micro-ICR: NeoPhotonics Class 40 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is designed for >60 GBaud symbol rates. The compact package is designed to be compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
  • Nano-ITLA: NeoPhotonics Nano-ITLA is based on the same proven and reliable high performance external cavity architecture as NeoPhotonics’ industry leading Micro-ITLA and maintains comparable ultra-narrow linewidth, low frequency phase noise and the low power consumption in a compact package approximately one half the size.

NeoPhotonics Multi-Rate CFP2-DCO modules are fully qualified. Telcordia testing has been successfully extended to 2000 hours of High Temperature Operating Life (HTOL) testing, showing the high reliability and performance of NeoPhotonics CFP2-DCO platform.

Multi-Rate CFP2-DCO modules supporting Metro (64G baud/DP-16 QAM) and Long Haul (64 G baud/DP-QPSK) applications are shipping in General Availability.

“Coupled with our recent demonstration of 800 km 400 Gbps transmission using our 400ZR+ QSFP-DD, our CFP2-DCO 400G 1500 km transmission brings the use of pluggable modules in regional and long haul networks closer to reality,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “The ability to implement a long haul coherent transponder in the size and power envelope of a pluggable module is a testament to the progress that has been made in photonic integration and DSP development, and has the potential to be a game changer for telecom as well as DCI networks,” concluded Mr. Jenks.

June 8, 2021 Update:

NeoPhotonics announced that its QSFP-DD and OSFP 400ZR pluggable modules are in General Availability and shipping to customers.

These products utilize NeoPhotonics Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser, combined with the latest generation of 7 nm node DSP (digital signal processing) technology, to provide full 400ZR transmission in a standard data center QSFP-DD or OSFP form factor that can be plugged directly into switches and routers. This greatly simplifies and cost reduces data center interconnect (DCI) networks by enabling the elimination of a layer of network equipment and a set of short reach client-side transceivers, and paves the way for similar benefits in metro networks.

These 400G modules are compliant with the OIF 400ZR Implementation Agreement and are interoperable with other manufacturers’ 400ZR modules that utilize a standard forward error correction (FEC) encoder and decoder.  These modules are capable of tuning to and transmitting within 75 GHz or 100GHz spaced wavelength channels, as specified in the OIF agreement, and operate in 400ZR mode for Cloud DCI applications.  For longer metro reaches, the modules are designed to support 400ZR+ modes.

NeoPhotonics QSFP-DD and OSFP modules have completed reliability qualification and have passed 2000 hours of High Temperature Operating Life (HTOL) as well as other critical tests per Telcordia requirements.

Nokia and Proximus (Belgium) demonstrate 1st implementation of 25GS-PON

Nokia and Proximus turned on what they call the world’s fastest fiber access network at a media event in Antwerp attended by the Belgian Minister of Telecommunications, the Mayor of Antwerp and executives and engineers from the two companies.

Operating over existing fiber with Nokia equipment deployed in the Proximus network, the first ever 25G PON live network connects the Havenhuis building in the Port of Antwerp with the Proximus central office in the middle of the city. The network speed exceeded 20 Gbps, making it the fastest fiber network in the world.

Proximus is the leading provider of fixed broadband networks in Belgium with 45.9% market share. The operator is accelerating the move to fiber, adding 10% coverage each year and is on target to reach at least 70% of homes and business by 2028. As part of its inspire 2022 vision, it is creating a high capacity open network which will be available to all operators, eliminating the need for fiber overbuild.

Rupert Wood, Research Director for Fiber Networks at Analysys Mason, said: “Today’s 25G PON achievement demonstrates the unlimited potential of fiber. This next evolution in fiber technology will provide enterprises with greater than 10 Gbs connectivity and the capacity needed to support 5G transport along with future next generation services such as massive scale Virtual Reality and real time digital twins.”.

Guillaume Boutin, CEO Proximussaid: “The activation of the first 25G PON network worldwide shapes our bold ambition to be a trendsetter, to become a reference operator in Europe and, why not, across the globe. Together with Nokia, we have achieved a technological leap forward that will become a key enabler of the digital and economy and society that we stand for. Today’s announcement is also an occasion to stand still and look at the pace at which we connect the citizens of Antwerp to the technology of the future. Thanks to huge investments, we are realizing an acceleration that is unseen in Europe, and I am convinced this will be crucial to remain competitive for us as a company, but also for Antwerp as a city and for our entire economy.”

Federico Guillén, President Network Infrastructure Nokia, said“10 years ago our companies launched the technology which enabled a switch to HD TV. Today we make history again with a network that is 200x faster. We are proud to support Proximus in enabling the world’s first 25G PON network, powered by Nokia’s Quillion chipset, which supports three generations of PON technologies. Quillion has been adopted by more than 100 operators since its launch last year and all operators deploying the Quillion based GPON and XGS-PON solution today have the capabilities to easily evolve to 25G PON.”

Nokia’s 25G PON solution utilizes the world’s first implementation of 25GS-PON technology and includes Lightspan access nodes, 25G/10G optical cards and fiber modems.

Nokia Lightspan FX and MX are high-capacity access nodes for massive scale fiber roll-outs. Usually located in telecom central office, they connect thousands of users via optical fibre, aggregate their broadband traffic and send it deeper in the network. The fiber access nodes can support multiple fiber technologies including GPON, XGS-PON, 25GS-PON and Point-to-Point Ethernet to deliver l wide range of services with the best fit technology..

Nokia ONT (Optical Network Termination) devices, or fiber optic modems, are located at the user location. They terminate the optical fiber connection and delivers broadband services within the user premises or cell sites.

Nokia supplied PON line cards with their Quillion chipset, which can handle 25 Gbps. The chipset can grow with gradual updates on an operator’s network. Nokia is already shipping the technology to 100 customers worldwide.

Nokia executives admitting during a webcast press conference today that its 25G PON tech still needed some work for large-scale deployments, but that it would be ready for large, prime-time rollouts in 2022, with enterprise and 5G backhaul applications expected to fuel initial demand.

PON (Passive Optical Networking) eliminates the need for active equipment on the connection, between the control panel and the end user’s network connection point. On the last mile, there is system of optical splitters that breaks the light signal into different wavelengths. This means the 25G connection can be shared by up to 32 households. Since end users do not constantly use the full connection, a high bandwidth per connection is still achievable.

FTTH Council Europe: FTTH/B reaches nearly 183 million (>50% of all homes)

Europe has passed over half of homes able to receive fiber broadband. According to the latest figures compiled by Idate for the FTTH Council Europe, 52.5% of homes will be covered by FTTH/B at the end of September 2020.  That’s up from 49.9% a year earlier.

FTTH Council Europe revealed the following:

• Number of homes passed by fiber (FTTH/B) reaches nearly 183 million homes in EU39.

• Europe’s fiber footprint (number of homes passed) expanded the most in the past year in France (+4.6M homes passed), Italy (+2.8M), Germany (+2.7M) and the UK (+1.7M).

• Three countries are accounting for almost 60% of homes left to be passed with fiber in the EU27+UK region.

• FTTH/B Coverage in Europe surpasses more than half of total homes.

• 16.6% growth in the number of fiber subscribers.

Iceland leads the European FTTH/B league table second year in a row.  70.7% of its households having fiber connections. Belarus (70.4%) and Spain (62.6%) came in second and third.

• Belgium, Israel, Malta and Cyprus enter the FTTH/B ranking for the first time.

The above figures cover 39 countries across Europe, where nearly 183 million homes have fibre access. For the EU and UK alone, penetration reached 43.8 percent in September, up from 39.4 percent a year earlier.

The report also shows fiber take-up is accelerating, with a subscriber penetration of 44.9 percent of lines in the 39 countries, compared to 43 percent in September 2019. In total there were 81.9 million FTTH/B subscribers in September 2020, up 16.6 percent from a year earlier. Annual growth was again strongest in France, with nearly 2.8 million subscribers added in the 12 months, followed by Russia with 1.7 million and Spain with 1.4 million.

The FTTH Council noted a shift in several countries in the past year where legacy infrastructure previously dominated. They are now moving faster towards fiber and even starting to look at shutting down copper networks. Nevertheless, three historically copper-strong countries – the UK, Germany and Italy – account for almost 60 percent of homes left to be passed with fiber in the EU27+UK region.

The countries with the highest fiber penetration across Europe are Iceland and Belarus, with over 70 percent of households using fiber broadband. Spain and Sweden are at over 60 percent, and Norway, Lithuania and Portugal over 50 percent.

“The telecoms sector can play a critical role in Europe’s ability to meet its sustainability commitments
by reshaping how Europeans work, live and do business. As the most sustainable telecommunication
infrastructure technology, full fibre is a prerequisite to achieve the European Green Deal and make the
European Union’s economy more sustainable. Competitive investments in this technology should,
therefore, remain a high political priority and we look forward to working with the EU institutions,
national governments and NRAs towards removing barriers in a way to full-fibre Europe” said Vincent
Garnier, Director General of the FTTH Council Europe.

About the FTTH Council Europe:

The FTTH Council Europe is an industry organization with a mission to advance ubiquitous full fibre based connectivity to the whole of Europe. Our vision is that fiber connectivity will transform and
enhance the way we live, do business and interact, connecting everyone and everything,
everywhere.

Fiber is the future-proof, climate-friendly infrastructure which is a crucial prerequisite for
safeguarding Europe’s global competitiveness while playing a leading global role in sustainability.
The FTTH Council Europe consists of more than 150 member companies.

Echo and Bifrost: Facebook’s new subsea cables between Asia-Pacific and North America

Facebook has revealed plans to build two new subsea cables between the Asia-Pacific region and North America, called Echo and Bifrost.  The social media giant also revealed partnerships with Google as well as Asian telecoms operators for the project.

Although these projects are still subject to regulatory approvals, when completed, these cables will deliver much-needed internet capacity, redundancy, and reliability.  The transpacific cables will follow a “new diverse route crossing the Java Sea, connecting Singapore, Indonesia, and North America,” and are expected to increase overall transpacific capacity by 70%.

Facebook says Echo and Bifrost will support further growth for hundreds of millions of people and millions of businesses. Facebook said that economies flourish when there is widely accessible internet for people and businesses.

Echo and Bifrost be the first transpacific cables through a new diverse route crossing the Java Sea. Connecting Singapore, Indonesia, and North America, these cable investments reflect Facebook’s commitment to openness and our innovative partnership model. The social media company works with a variety of leading Indonesian and global partners to ensure that everyone benefits from developing scale infrastructure and shared technology expertise.

Facebook will work with partners such as Indonesian companies Telin and XL Axiata and Singapore-based Keppel on these projects.

Kevin Salvadori, VP of network investments at Facebook, provided further details in an interview with Reuters. He said Echo is being built in partnership with Alphabet’s Google and XL Axiata.  It should be completed by 2023. Bifrost partners include Telin, a subsidiary of Indonesia’s Telkom, and Keppel.  It is due to be completed by 2024.

Aside from the Southeast Asian cables, Facebook was continuing with its broader subsea plans in Asia and globally, including with the Pacific Light Cable Network (PLCN), Salvadori said.

“We are working with partners and regulators to meet all of the concerns that people have, and we look forward to that cable being a valuable, productive transpacific cable going forward in the near future,” he said.

Indonesia

Facebook noted that Echo and Bifrost will complement the subsea cables serving Indonesia today. These investments present an opportunity to enhance connectivity in the Central and Eastern Indonesian provinces, providing greater capacity and improved reliability for Indonesia’s international data information infrastructure. Echo and Bifrost complement the subsea cables serving Indonesia today, increasing service quality and supporting the country’s connectivity demands.

This is all part of Facebook’s continued effort to collaborate with partners in Indonesia to expand access to broadband internet and lower the cost of connectivity. Facebook has partnered with Alita, an Indonesian telecom network provider, to deploy 3,000 kilometers (1,8641 miles) of metro fiber in 20 cities in Bali, Java, Kalimantan, and Sulawesi. In addition, we are improving connectivity by expanding Wi-Fi with Express Wi-Fi.

While 73% of Indonesia’s population of 270 million are online, the majority access the web through mobile data, with less than 10 percent using a broadband connection, according to a 2020 survey by the Indonesian Internet Providers Association.  Swathes of the country, remain without any internet access.

Singapore

In Singapore, Echo and Bifrost are expected to provide extra subsea capacity to complement the APG and SJC-2 subsea cables. Building on Facebook’s previously announced Singapore data center investments, Echo and Bifrost will provide important diverse subsea capacity to power Singapore’s digital growth and connectivity hub. Singapore is also home to many of Facebook’s regional teams.

The Asia-Pacific region is very important to Facebook.  In order to bring more people online to a faster internet, these new projects add to Facebook’s foundational regional investments in infrastructure and partnerships to improve connectivity to help close the digital divide and strengthen economies.
