LONDON -- Huawei and Openreach have tested a 25G/100G symmetric PON prototype to prepare for 5G speeds, as well as manage network demands from ultra-high definition (UHD) video and high-value enterprise leased lines. The technology will enable operators to increase speeds and bandwidth on existing network infrastructure, helping to future-proof their networks.

The prototype supports a single channel of 25 Gb/s, meeting fiber to the x (FTTx) requirements and supports two or four channels for business and mobile backhaul services. When tested in Openreach labs, the prototype supported four channels which delivered a maximum symmetric bandwidth of 100 Gb/s.

Huawei developed the 25G/100G symmetric PON prototype based on the MA5800, a commercially-used distributed optical line terminal (OLT). When deploying this prototype, existing optical distribution network (ODN) infrastructures can be re-used protecting investments and realizing smooth evolution.

Tim Whitley, BT's Managing Director for Research & Innovation, said: "This test proves that Openreach can deliver user services with higher bandwidth based on their fiber networks, unlocking greater potential for broadband networks. We will continue to maintain advanced networks to meet users' potential demands in the future."

Jeff Wang, President of Huawei's Access Network Product Line, said: "The success of the 25G/100G symmetric PON test indicates that Huawei is able to cope with big broadband services in the future. Huawei wants to work with industrial partners to promote the integration of next-generation PON standards in the industry, and ensure that the same set of standards and systems are used for optical access networks."
