BT Tests G.fast in Adastral Park Lab

BT's Adastral Park R&D centre in Ipswich is conducting trials of G.fast technology in conjunction with Fibre To The Distribution Point (FTTdp) architecture.

Initial testing achieved downstream speeds of around 800 Mbps over a 19m length of copper, combined with upstream speeds of more than 200 Mbps. Speeds of around 700/200 Mbps were also achieved over longer lines of 66m.

BT said its fibre network rollout, which is being carried out by Openreach, currently passes more than 20 million UK premises using a mix of Fibre to the Premises (FTTP) and Fibre to the Cabinet technology (FTTC).  FTTPdp and G.fast offer potential cost savings.
