On June 9, 2015, Huawei and BT were jointly presented with the Fixed Network Infrastructure Innovation Award at the Global Telecoms Business (GTB) Innovation Awards 2015. This award was “recognition for their close collaboration on the world’s first 3 Tbit/s real-time super-channel technological innovation and deployment of 400G OTN on BT’s live Belfast-Dublin WDM network,” the citation stated.
The optical transmission speed of 3 Tbit/s during testing, which is said to be the highest transmission speed in the industry, was demonstrated on a 359km optical network between London and Suffolk. The partners said the achievement is a new record of optical transmission speed with the highest spectrum usage of 5.97 b/s/Hz – 200% higher than previous usage.
Paul Salusbury Huawei’s BT Global Account Director said, “We are delighted to have worked together with BT on this ground-breaking transmission test. It underlines Huawei’s strategy to work in collaboration with our partners to bring benefits to customers and create a better and faster connected UK”.
Huawei demonstrated how technological innovation helps maximize the returns of operator investments on existing optical fiber networks and improve the network infrastructure to meet increasing bandwidth requirements. The pair deployed Europe’s first 400G OTN on BT’s live Belfast-Dublin network. This 400G OTN transmits 400G signals over idle waves on the live network. In addition, it can also carry existing 10G, 40G, and 100G services.
The GTB award for Fixed Network Infrastructure Innovation represents the industry’s recognition of Huawei for its continuous technological innovation and focus on addressing operator challenges. Huawei is committed to further investment in innovation and commercial deployment practices to help operators build future-oriented network infrastructure and meet requirements for higher bandwidth.
