ADTRAN, a global provider of next-generation networking solutions, has reported further details on trials of G.fast technology based on its fibre-to-the-distribution point (FTTdp) solution, that include BT's large scale trial deployments in the UK.
Since ADTRAN demonstrated what it claimed was the first fully sealed FTTdp solution in early 2014, it has continued to lead in G.fast trial deployments. ADTRAN stated that via this technology it is currently meeting demand from more than 60 service providers on six continents that have validated the solution's advanced design and performance.
In particular, the trials with UK operator BT that are being conducted in the town of Huntingdon in Cambridgeshire, reaching over 2,000 premises, are the latest to include the ADTRAN 500G Series G.fast solutions. The company noted that G.fast, a viable gigabit broadband technology, can allow carriers to deliver up to five times the broadband bandwidth currently offered by the most advanced cable providers in the UK.
ADTRAN claims that its solutions have significantly exceeded original expectations through implementing technology that enhances the performance of G.fast both in terms of reach and speed. These capabilities are designed to enable service providers to shift from the more costly FTTP deployment model to emerging FTTdp models and more recently fibre-to-the-cabinet (FTTCab) topologies.
In addition, combined with ADTRAN's objective of increasing the port density of G.fast equipment in the future, the company plans to enable further potential savings for large service providers for every 50 metres of additional customer reach.
ADTRAN's G.fast solutions also feature support for open software-defined network (SDN) models designed to allow rapid plug-and-play deployment capability within existing multi-vendor FTTx infrastructure.
ADTRAN stated that with over 100,000 sealed micro DSLAMs installed in FTTdp and FTTCab deployments to date, many in locations with harsh and extreme environments such as the Middle East, Finland, Mexico and Alaska, ADTRAN has a proven track record of delivering the type of environmentally sealed and remotely powered solutions required for the successful roll-out of G.fast.
In May of last year, BT announced trials of G.fast technology at its labs in Adastral Park. The announcement followed a proposal by BT to deploy the technology to enable speeds of up to 500 Mbit/s across the UK within the next decade after the completion of two large-scale field trials of G.fast in Huntingdon, Cambridgeshire and Gosforth, Newcastle-upon-Tyne.
BT had previously announced the opening of an ultra-fast broadband lab at the Adastral Park R&D centre, where it would study the technical capabilities of G.fast hardware from system vendors including ADTRAN, Alcatel Lucent and Huawei.
Regarding the G.fast trials, Mike Galvin, BT's MD of service, strategy and operations, said, "Providing fibre to every home or business in a given community can be a logistical and financial challenge… rather than relying on fibre for the entire network, G.fast solutions such as ADTRAN's use existing copper assets for the last step… this allows BT to provide the ultra-fast broadband customers demand, while reducing the time and cost of running fibre all the way to the premises".
