US-based hardware vendor Ciena and British fixed line incumbent BT have outlined details of what they termed ‘a series of pioneering trials over the latter’s UK optical core network infrastructure’. With the trials having taken place in March 2013, the duo confirmed that they had demonstrated support for Terabit-rate speeds over BT’s core network with a series of 100G, 200G, 400G and, most notably, an ‘800G super-channel’ transmission trials using WaveLogic 3 transceivers – deploying both single and super-channel techniques. Meanwhile, although it was noted that higher transmission speeds had been achieved in a laboratory environment, the company’s highlighted the fact that it had achieved its results over a deployed 410km network link between BT’s Adastral Park Research and Development Centre in Ipswich and the BT Tower in Central London.
Commenting on the development, BT’s chief network architect Neil J. McRae said: ‘Since [BT’s launch] and with the recent explosion in global connectivity, we have constantly looked for new ways to future proof our infrastructure and provide more bandwidth for the next generation of applications and services. These trials prove that we’re heading in the right direction, and we’re very proud of our role in this latest milestone in the history of communications.’
