BT claims world speed record with core network trials

26 May 2016

British fixed line incumbent BT claims to have achieved the fastest ever speeds of 2Tbps over a live core network link spanning 727km between London and Dublin in a trial conducted in partnership with Huawei. In a press release BT noted that, having used optical superchannel technology to deliver ultrafast speeds over a closed trial network in 2014, it had now applied this same technology to the commercial fibre link carrying live customer traffic between London and Dublin. Further, BT has also announced the successful transmission of speeds reaching 5.6Tbps over a single optical fibre running on its trial network between the BT Labs in Adastral Park and the BT Tower in London, beating a previous record of 3Tbps set in 2014.

According to BT, the technology and techniques pioneered in its labs – using Terabit superchannels and flexible grid infrastructures – will allow it to avoid a ‘capacity crunch’, by squeezing far more bandwidth out of its existing core optical networks.
