Broadband Forum and LAN Laboratory Expand Certification Program to include XGS-PON

As demand for fiber networks continues to grow, the Broadband Forum has expanded its  BBF.247 Optical Network Unit (ONU) Certification Program to include XGS-PON.

This latest update extends the program to a variety of key features needed by operators deploying XGS-PON networks. The certification is just one piece of Broadband Forum’s vision to provide network operators with the tools, open specifications, and open source references necessary to bring new services and technologies to their customers more rapidly. Certified ONU products can be deployed quickly, with improved interoperability to existing Optical Line Terminal (OLT) equipment already deployed. Similarly, certified ONU products will also work directly with newer Broadband Forum specifications, including the forthcoming virtual OMCI specifications and software defined access networks.

The XGS-PON extensions add to the BBF.247 G-PON initiative – which has now certified nearly 100 products since its launch in 2011. The new test plan will see ONUs undergo rigorous testing at Broadband Forum’s official certification program test laboratory Laboratoire des Applications Numeriques (LAN Laboratory), using MT2’s ONU testing solution. The work will confirm conformance to the latest PON ITU-T standards, providing network operators with assurance that they can deliver efficient networks and a high-quality customer experience. New additions to the technology are also now tested, including extended OMCI messages format, Enhanced Unicast & Multicast Operations, and Capacity Tests & Performance Monitoring. This increases the number of certification test cases by more than 50% compared to the previous version.

Eight products, including single or multi-user port ONUs/L2 and Residential Gateways from Altice Labs, CommScope, Huawei, Humax, KAONMEDIA, Sagemcom, Sercomm and ZTE have already been certified under the new BBF.247 certification program.

“The introduction of XGS-PON certification by Broadband Forum is a significant and positive step for the PON ecosystem as interoperability will encourage growth,” said Jaeseok Kim, Head of Infra Planning at SK Broadband. “This will become increasingly important as more operators look to upgrade existing network to meet consumer demand for Gigabit + speeds.”

Claudio Mathys, Product Manager Wireline Access Networks at Swisscom (Schweiz) AG, added: “Establishing interoperability and testing requirements are key elements in a liberated market. The introduction of XGS-PON from Swisscom as a technology leader – in conjunction with the certification and testing program from Broadband Forum – will significantly enhance the confidence from our competitors for CPE certification as based on industry standards and independent references. Achieving Broadband Forum certification is the entry ticket for connectivity to our network. We will definitely avoid the painful experience made with xDSL interoperability/complexity – right from the beginning.”

Hugues Le Bras, Network Engineer in Fixed Access Networks at Orange, said: “The role of interoperability and standards has only become more important as broadband grows in popularity and operators upgrade their networks to meet consumer demand. Orange already requests BBF.247 certification for each ONU deployed on the field. However, this expansion of Broadband Forum’s certification program will give us confidence when deploying next-generation technology that will enable the future era of connectivity. The latest additions to the certification also bring new features, such as flexibility and monitoring, which are essential for Orange throughout the ONU life.”

A future XGS-PON interoperability test event will take place at LAN Laboratory, in Tauxigny, France, from October 5 to 9, 2020, allowing vendors worldwide to exercise their OLT or Optical Network Terminal (ONT) solutions against each other. The event will give all equipment vendors the opportunity to improve the interoperability of their products by testing them against the other solutions presented at the event.

“Our existing G-PON certification has made a significant impact on ensuring products meet standards, and this latest expansion of the program will give operators the confidence to roll out mass XGS-PON deployments,” said Robin Mersh, CEO at Broadband Forum. “We now want to instill this same assurance in the industry for upcoming ITU PON technology, including XGS-PON and NG-PON2. XGS-PON is a major step in network evolution, supporting the expansion of 5G and through BBF.247 certification, we can ensure network interoperability.”

Thierry Doligez, Director of LAN Laboratory, said: “Both operators and vendors increasingly recognize the importance of certification in order to speed up deployment and we are proud to partner with Broadband Forum on this extension of its G-PON certification program. As operators move to upgrade their networks to meet increasing consumer demand, the new testing will make sure they are investing in trusted products which will guarantee a certain level of service. ONU manufacturers will also benefit from this substantial program update as it will give them the chance to prove their conformance against enhanced features.”

AT&T deploys XGS-PON to power FTTH nets

AT&T has enhanced its fiber-to-the-home (FTTH) “last mile” network by deploying XGS-PON [1.] technology which will be live in 40 markets.  AT&T will start out providing 1 gigabit download speeds before eventually boosting them to 10 gigabits per second in both directions as it upgrades from GPON networks. The company said it has deployed XGS-PON in “a few thousand locations” noted that it has employed multiple vendors in the process. It’s part of AT&T’s road map to virtualize network access functions within its last mile network.

NOTE 1.  XGS-PON is a fixed wavelength symmetrical 10 Gbps passive optical network technology.

The “X” in XGS represents the number 10, and the letter “S” stands for symmetrical, XGS-PON = 10 Gigabit Symmetrical PON. An earlier, non-symmetrical 10 Gigabit PON version (XG-PON) was limited to 2.5 Gbps in the upstream direction.

PON technology originated in the 1990’s and has continued to develop through multiple iterations with differing wavelengths, speeds and components emerging as the technology has improved. The common denominator of all fiber optic PON networks remains the unpowered or passive state of the fiber and its splitting or combining components, i.e. no active elements such as optical amplifiers, which would require power, are present in the network. With streaming, high definition, 5G and other emerging technologies continually pushing bandwidth demands, the development of XGS-PON and other standards has proven to be essential.

Simultaneous upstream and downstream transmission over the same fiber is made possible through wavelength division multiplexing (WDM). This technology allows one XGS-PON wavelength or color of light transmission for upstream and another for downstream.

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

Two years ago, AT&T completed trials of 10 Gbps XGS-PON by using Open Source Access Manager Hardware Abstraction (OSAM-HA) software in Atlanta and Dallas. OSAM-HA was released into the Open Networking Foundation (ONF) in 2017 as VOLTHA.

  • OSAM, which used the Open Networking Automation Platform (ONAP) platform that AT&T helped develop, is a vendor-agnostic operational suite for managing consumer and business broadband access network elements and capabilities. ONAP has undergone several major releases over the past few years.
  • ONF’s Virtual OLT Hardware Abstraction (VOLTHA) open source software project, which is a component of ONF’s SDN Enabled Broadband Access (SEBA) platform, abstracts a PON network to make it manageable as if it were a standard OpenFlow switch.
  • SEBA describes how to assemble a collection of open source components to build a virtualized PON network to deliver residential broadband and mobile backhaul. SEBA uses a disaggregated white-box approach for building next generation access networks by using open source.

“AT&T continues to work with open communities such as ONF, ONAP, and OCP (Open Compute Project) to drive innovation, time-to-market, and cost improvements as we build next generation networks,” the company said in a March 4th statement in regard to a request for more information on the deployments in the 40-plus cities.

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

Conventional wisdom in the fiber broadband industry suggests NG-PON2 is the platform most providers will eventually adopt, with XGS-PON as an interim step to get there.

Verizon seems to be leapfrogging that approach. For what it’s worth regarding conventional wisdom, the AT&T spokesperson tells Telecompetitor, that “AT&T is not currently planning to use NG-PON2 at this time.”
