Separately, BT and Huawei achieved 5.6Tbps along a closed 359km fibre loop between the BT Tower in central London and BT s research and development facility at Adastral Park in Suffolk.

It s important that our core networks keep pace with the growth in bandwidth demands driven by take-up of high-speed fibre broadband, HD content, 4G smartphones and tablets and in the future, 5G services, said Howard Watson, CEO of BT Technology, Services and Operations TSO .

These landmark trials show that we can easily turn up the dial to deliver the speeds needed in our core networks to stay well ahead of rising customer demand.

Ultra-High-Speed optical networks are an indispensable infrastructure for the future of digital life, and this is an area where Huawei is investing, to help telcos such as BT squeeze as much capacity out of their core networks as possible, added Zha Jun, president of Huawei s fixed network product business.

Research projects around the world are seeking to boost the speed and capacity of wired and wireless networks as entertainment and cloud applications, along with the Internet of things IoT , drive demand.
