Orange and Nokia demo 600Gb/sec transmission over a 914 km optical network; Nokia 25G PON

Nokia and Orange announced the completion of a network trial using the Nokia PSE-Vs, its fifth generation super coherent optics.  With this field trial, Orange has successfully validated a planned upgrade of its long-haul backbone networks to support new high-bandwidth 400 Gb/sec services, and the ability to scale fiber capacity up to 600Gb/sec. This represents an increase in spectral efficiency by 50% compared to prior technologies on its long distance optical network.

The trial was performed in real-world conditions using Nokia PSE-Vs super coherent optics in production-ready optical transport hardware, just 16 months after the lab prototype trial done on Orange’s live network.  Orange and Nokia demonstrated error-free performance at a data rate of 600Gb/sec over a 914 km network between Paris and Biarritz, under challenging  live network conditions. The fiber network consisted of 13 spans of Orange’s existing network, through multiple cascaded reconfigurable optical add/drop multiplexers (ROADM), using 100GHz WDM spectrum channels.

Jean-Luc Vuillemin, Vice President of International Networks and Services at Orange, said: “With the booming market bandwidth requirement and need for scalability and flexibility, it is important that Orange continues to support an ever-greater network scale and new high-bandwidth services across our terrestrial and subsea global footprint.

Validating super coherent optics with Nokia represents an important enabler for future-proof networks which will bring spectral efficiency and operational deployment flexibility to our customer solutions. Furthermore this technology will allow for power savings by nearly 50%, which is key to our objective of developing greener networks for our customers. ”

James Watt, Head of Optical Networks Division, Nokia, said: “We are delighted to work with Orange in continued support of their network upgrade plans. With the introduction of the PSE-Vs super coherent capabilities across our entire 1830 portfolio, Nokia enables spectrally-efficient transport at 600Gb/sec over real-world long haul networks, and 400Gbps services over ultra long haul networks spanning multiple 1000’s of kilometers.”

Earlier this week, Nokia and Bell Canada announced the first successful test of 25G PON fiber broadband technology in North America at Bell’s Advanced Technical Lab in Montréal, Québec.

The trial validates that current GPON and XGS-PON broadband technology and future 25G PON can work seamlessly together on the same fiber hardware, which is being deployed throughout the network today. 25G PON delivers huge symmetrical bandwidth capacity that will support new use cases such as premium enterprise service and 5G transport.  Nokia’s 25G PON solution utilizes the world’s first implementation of 25G PON technology and includes Lightspan and ISAM access nodes, 25G/10G optical cards and fiber modems.

For the past decade, Bell has been rolling out fiber Internet service to homes and businesses across the country, a key component in the company’s focus on connecting Canadians in urban and rural areas alike with next-generation broadband networks. With this successful trial, Bell can be confident that its network will absorb the increased capacity of future technologies and connect Canadians for generations to come.

Stephen HoweEVP & Chief Technology Officer, Bell, said:
“As part of Bell’s purpose to advance how Canadians connect with each other and the world, we embrace next-generation technologies such as 25G PON to ensure we remain at the forefront of broadband innovation. Our successful work with Nokia to deliver the first 25G PON trial in North America will help ensure we maximize the Bell fiber advantage for our customers in the years to come.”

Jeffrey Maddox, President of Nokia Canada, said: “Nokia innovations powered the fiber networks and the connectivity lifeline that carried Canadian homes and businesses through the pandemic. 25G PON innovations will drive the next generation of advances in our connected home experience.”

Bell and Nokia have closely collaborated over the years on many industry breakthroughs, such as the first Canadian trial of 5G mobile technology in 2016. Bell continues to work with Nokia to build and expand its 5G network across Canada.

Microchip and Cisco-Acacia Collaborate to Progress 400G Pluggable Coherent Optics

Bandwidth growth, driven by the expansion of data centers and 5G network build-outs, is expected to drive the need for faster coherent Dense Wavelength Division Multiplexing (DWDM) pluggable optics. Consequently, Data Center Interconnect (DCI) and metro Optical Transport Network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support these hyper-connected architectures.

Microchip Technology (a fabless semiconductor company) and Cisco’s Acacia unit are working together to validate the interoperability of their 400G pluggable optics componentsMicrochip’s DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics.

The purpose of the collaboration is to establish an ecosystem to support 400G CFP2-DCO, QSFP-DD and OSFP modules for the 400ZR specification as well as the OpenZR+ and Open ROADM Multi-Source Agreement (MSA) applications.

The collaboration between Microchip and Acacia helps to enable the use of 400G coherent pluggable optics in OTN and Ethernet systems as follows:

  • For converged packet/OTN optical platforms, Microchip’s DIGI-G5 and Acacia’s 400G CFP2-DCO module are designed to enable terabit-class OTN switching line cards, mux/transponders, and switch/transponders. The DIGI-G5 interoperates with Acacia’s 400G CFP2-DCO module using a Flexible OTN (FlexO) or NxOTU4 interface to efficiently support OTN traffic, including Open ROADM MSA interface modes and 200G/400G ITU-T standards currently being drafted.
  • For compact modular optical systems, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable 400G flexible line rate muxponders/transponders with support for multiple client optics types including QSFP28, QSFP-DD, and OSFP modules, helping service providers to transition from 100 GbE to 400 GbE using the same hardware.
  • For data center routing and switching platforms, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable dense 400 GbE or FlexE with per port MACsec encryption coherent line cards. This helps customers leverage IP routers/switches over DWDM (IPoDWDM) infrastructure in DCI deployments.

“DIGI-G5 and META-DX1 have enabled our optical transport, IP routing and Ethernet switching customers to implement a new class of multi-terabit OTN switching and high-density 100/400 GbE and FlexE line cards that deliver on stringent packet timing and integrated security capabilities for the build out of cloud and carrier 5G-ready optical networks,” said Babak Samimi, vice president for Microchip’s Communications business unit. “Our interoperability efforts with Acacia help to demonstrate that an ecosystem for volume deployment of these new line cards with pluggable 400G coherent optics exists.”

“With Acacia’s 400G coherent modules verified to interoperate with Microchip’s DIGI-G5 and META-DX1 devices, we see it as a robust solution designed to address network capacity growth and improved efficiency,” said Markus Weber, senior director DSP, product line management of Acacia, now part of Cisco. “The compact size and power efficiency of our 400G OpenZR+ CFP2-DCO modules were designed to help network operators deploy and scale capacity of high-bandwidth DWDM connectivity between data centers and in metro networks.”

Kevin So, associate director of product line management and marketing at Microchip, told Fierce Telecom that the pair have a history of collaboration that goes back to work on 100G. He said their latest effort is meant to proactively eliminate elements of risk operators face as they begin to upgrade to the latest 400G technology.  While most solutions are based on industry standards, So cautioned that’s not always a guarantee that components from different companies will work well together.

“I’ve seen in our industry often standards are written, people think things are going to work and then you show up at a carrier lab and that’s when you discover problems.  Standards still do not necessarily always ensure everything is interoperable ready to go, and it can be a barrier for ultimately our customers and service providers in deploying it,” Mr. So said.

The companies stated they successfully validated interoperability between their respective components for 400G, ZR and OpenZR+ configurations in converged packet and OTN optical platforms, compact modular optical systems and data center routing and switching platforms.

So said Microchip’s work with Acacia started in the pre-silicon stage, ensuring the interfaces and designs they were pursuing were compatible. Once the silicon in question became available, the pair “tested these components together as a system to make sure it’s robust enough.”

Tom Williams, director of marketing for Acacia told Fierce Telecom, “This interop testing demonstrates that leading vendors are working together to streamline the integration process. There wasn’t any expectation of issues, but it builds confidence to know that the vendors have already done this work directly.”

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.

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.

The company recently announced that it had used its QSFP-DD coherent pluggable transceiver to transmit at a 400 Gbps data rate over a distance of 800 km in a 75GHz-spaced DWDM system with more than 3.5 dB of OSNR margin in the optical signal while remaining within the power consumption envelope of the QSFP-DD module’s power specification.

“This demonstration of high data rates over longer distances shows the potential of these game-changing products, and we expect to see increasing deployment of coherent pluggable modules with different use cases, from data center interconnect to metro and regional applications as well as 5G wireless backhaul,” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “Since the beginning of coherent transmission, NeoPhotonics has been at the forefront in meeting the volume needs of our customers, as is indicated by our recent announcement that we had shipped a cumulative total of more than two million ultra-narrow linewidth tunable lasers,” concluded Mr. Jenks.

Internet 2’s Next Generation Infrastructure team deploys 800Gbps optical link

On February 26, 2021, Internet2 deployed its first 800 Gbps single-carrier optical circuit between Phoenix and Tucson, AZ as part of its Next Generation Infrastructure (NGI) program.

This milestone marks the first 800G native link to be deployed by a U.S. research and education network.   The optical circuit leverages a 102 Ghz carrier generated by a single Ciena Waveserver 5 transponder at each endpoint.

On February 25, 2021, the Internet2 project team completed the upgrade of all Reconfigurable Optical Add-Drop Multiplexers (ROADMs) to flex spectrum on all east-west long-haul routes nationwide. Additionally, the majority of the optical fiber was upgraded from LEAF to SMF28 to better match the coherent transmission technologies being used to convey the new 800 Gbps optical link.

Flex-grid ROADM and fiber route upgrade status as of February 25. Red segments and sites have been upgraded. Black segments are additional route upgrades being made as fiber becomes available. 

Internet2 plans to rapidly expand its 400G and 800G transmission capabilities along these newly flex-grid enabled routes; more link capacity will come online as our phase 2 hardware deployment team (GDT) continues to move across the country. The Internet2 team is deploying the Cisco 8200 and Ciena Waveserver 5 platform. Completion is targeted for the end of this month (March 2021).

The successful deployment of this initial 800 Gbps optical link is the culmination of thousands of hours of effort from both the Internet2 community and teams in many organizations, including Internet2, GlobalNOC at Indiana University, Ciena, Lumen, and GDT.

Just two weeks ago, Telefonica said it had trialed an 800 Gbps optical link, using Huawei and Nokia network equipment.  However, there are no 800 Gps links in any commercial production network, as far as we can determine.

Windstream Wholesale and Infinera Complete Successful Trial of LR8-Based 400GbE Client-Side Services

Windstream’s Wholesale Division recently completed a 400 gigabit Ethernet (400 GE)  trial pairing the client-side transmission with 400GbE-LR8 QSFP-DD pluggable interfaces on Infinera’s platform.  Transmission used a single-carrier 600G wavelength, which the companies announced as an industry first.
Pluggables have gained momentum in optical technology as web-scale companies, service providers and data center operators look to deploy some 400G gear this year and even more next year.
“The ability to support 400GbE services with a wide-variety of client interfaces and to carry those services across metro, regional and long-haul distances enables Windstream to seamlessly support their customers’ evolving connectivity needs,” said Infinera’s said Glenn Laxdal, senior vice president and general manager of product management, in a press release.
Infinera’s 600-Gbps enabled Groove (GX) G30 Compact Modular Platform was used in the 400 GE trial.  A G30 version of the Groove was fitted with a 2x600G per wavelength muxponder via a CHM-2T sled. The 400GbE service was carried via a single-carrier 600-Gbps wavelength.Coriant, which originally developed the Groove platform, announced 600-Gbps capabilities for the system shortly before the company was acquired by Infinera in 2018 (see “Coriant adds 600G transmission to Groove via CloudWave T” and “Infinera closes Coriant acquisition”).

Windstream Wholesale’s optical infrastructure was designed to support high-speed optical services using state-of-the-art flex grid spectrum and flexible colorless-directionless-contentionless (CDC) architecture. Flex grid, which is often paired with CDC, allows service providers to optimize the allocation of spectrum on long-haul fiber based on the required speed and reach of each wavelength.  All of this enables Windstream to tap into cost-effective 400G today, with 600G and 800G wavelengths available down the road.

“Our customers’ bandwidth requirements are growing rapidly, and Windstream is increasing network capacity to meet this demand,” said Buddy Bayer, chief network officer at Windstream. “Infinera’s GX G30 Compact Modular Platform provides an ultra-efficient transport solution enabling us to offer 400GbE services to support our customers’ high-bandwidth needs.  The use of LR8 clients with a single mode fiber interface and a 10-kilometer reach provides an extremely cost-effective solution by enabling us to extend these services directly to our customers’ premises.”

Windstream Wholesale is currently engaging with customers for initial deployment of the end-to-end 400G Wave service. For more information on how you can bring 400G Wave services to your company, call 1-866-375-6040.

Cignal AI: North American Optical Sales Rebound In 2019

Long Haul WDM Spending Reaches Record Levels:

Recent optical equipment sales in North America were encouraging – up more than 25% for 4Q19 and 10% for all of 2019 according to the most recent Transport Hardware Report from research firm Cignal AI.

The North American packet market for Access and Aggregation routing devices also grew strongly in the fourth quarter as demand for Edge and Core switching and routing dropped off dramatically. 5G and other access rollouts boosted growth in the Access and Aggregation market segment.
“After three years of North American spending declines as operators focused capex on wireless and access, optical hardware sales for the region revived and grew at a healthy pace for 2019, while packet hardware sales remained flat,” said Scott Wilkinson, Lead Analyst at Cignal AI. “Market leaders Ciena, Infinera, and Cisco all achieved optical sales growth of more than 25% in 2019.”
