AT&T to launch software-based 10G XGS-PON trial

AT&T announced it will conduct a 10 Gbit/s XGS-PON field trial in late 2017 as it progresses with plans to virtualise access functions within the last mile network.

The next-generation PON trial is designed to deliver multi-gigabit Internet speeds to consumer and business customers, and to enable all services, including 5G wireless infrastructure, to be converged onto a single network.

AT&T noted that XGS-PON is a fixed wavelength symmetrical 10 Gbit/s passive optic network technology that can coexist with the current GPON technology. The technology can provide 4x the downstream bandwidth of the existing system, and is as cost-effective to deploy as GPON. As part of its network virtualisation initiative, AT&T plans to place some XGS-PON in the cloud with software leveraging open hardware and software designs to speed development.
AT&T has worked with ON.Lab to develop and test ONOS (Open Network Operating System) and VOLTHA (Virtual Optical Line Terminator Hardware Abstraction) software. This technology allows the lower level details of the silicon to be hidden. AT&T stated that it has also submitted a number of open white box XGS OLT designs to the Open Compute Project (OCP) and is currently working with the project to gain approval for the solutions.

The company noted that interoperability is a key element of its Open Access strategy, and prompted the creation of an OpenOMCI specification, which provides an interoperable interface between the OLT and the home devices. This specification, which forms a key part of software-defined network (SDN) and network function virtualisation (NFV), has been distributed to standards and open source communities.



  • AT&T joined OCP in January 2016 to support its network transformation program. Earlier this year at the OCP Summit Edgecore Networks, a provider of open networking solutions and a subsidiary of Accton Technology, announced design contributions to OCP including a 25 Gigabit Ethernet top-of-rack switch and high-density 100 Gigabit Ethernet spine switch. The company also showcased new open hardware platforms.
  • At the summit, Edgecore displayed a disaggregated virtual OLT for PON deployment at up to 10 Gbit/ based on the AT&T Open XGS-PON 1 RU OLT specification that was contributed to the OCP Telco working group.
  • Edgecore's ASFvOLT16 disaggregated virtual OLT is based on the AT&T Open XGS-PON 1 RU OLT specification and features Broadcom StrataDNX switch and PON MAC SOC silicon, offering 16 ports of XGS-PON or NG-PON2, with 4 x QSFP28 ports and designed for next generation PON deployments and R-CORD telecom infrastructure.

BT Tests 10G XGPON in Cornwall


BT launched a trial of 10 Gbps XGPON access technology over a live network in Cornwall.  The trial, which uses equipment from ZTE, runs in tandem with the company’s existing 330Mbps service on the same Openreach fiber.

Cornwall based engineering firm Arcol UK Ltd. is connected by a direct fiber link from its offices to BT’s exchange in Truro, and is the first business in the country to enjoy the record-breaking speeds.  Until recently, Arcol’s 40 staff had shared a 1.5Mbps internet connection. BT said the demonstration aims to show how even faster speeds could be provided over Cornwall’s new fiber infrastructure in the future by upgrading the electronics at the exchange and in user premises.

Ranulf Scarbrough, Program Director for the Cornwall SuperFast Broadband Program, said: “What is exciting about this trial is that these hyper-fast speeds have been obtained over the exactly the same fiber that carries BT’s fiber broadband services today. All we are doing is changing the electronics at either end.  This trial shows we are thinking and ready for the future even though there are no current plans to deploy this technology. A lot of this project is about future proofing – making sure that it’s not just the fastest speeds today but that we can continue to be at the cutting edge for five, ten, twenty years.”

Huawei Shows 40G PON Prototype with 1:512 Split Ratio

Huawei announced a prototype PON platform that delivers 40 Gbps downstream and 10 Gbps upstream. The system, which has been tested and certified by the China Telecom Beijing Research Institute, supports a 1:512 optical splitting ratio and a transmission reach of 20 kilometers.


“Huawei's 40G PON system is highly compatible with existing GPON and XGPON systems and its transmission convergence layer maximally leverages existing GPON and XGPON structures,�? said Dr. Frank J. Effenberger, Huawei's chief optical access technology expert. “We are pleased to note that Huawei's solution has gained wide-ranging support from international standardization organizations like FSAN and ITU-T.�?http://www.huawei.com

BroadLight Partners with Korea's ETRI on XGPON

BroadLight is collaborating with Korea's National Electronics and Telecommunications Research Institute (ETRI) to develop and promote XGPON technology. The partnership aims to ensure a fully standardized XGPON (ITU-T G.987) initial deployment in Korea. BroadLight and ETRI are using their existing XGPON OLT and ONT technology for end to end interoperability testing. The test plan is based on efforts by FSAN to launch the first worldwide XGPON interoperability event. BroadLight plays an instrumental role in preparing this test plan as part of its active role with FSAN.
