Bell Canada rolls out commercial 400G wavelength on fibre optic backbone

Offering faster connectivity, increased capacity, low latency and higher energy efficiency for major cloud operators, content providers and carriers moving massive amounts of data

MONTRÉAL, April 22, 2021 – Bell Canada today announced commercial 400G wavelength service that employs Ciena’s (NASDAQ:CIEN, news, filings) WaveLogic 5 Extreme technology to deliver the significantly increased connectivity speeds and capacity required by the largest cloud and data centre providers while optimizing network performance and energy efficiency.

“Bell 400G wavelength service efficiently delivers the speed and capacity necessary to meet the fast-growing demand of bandwidth-intensive operators moving massive amounts of data and content to the cloud,” said Ivan Mihaljevic, Senior Vice President, Wholesale at Bell Canada. “Bell’s unparalleled network infrastructure and customer support, coupled with Ciena’s market-leading optical wavelength technology, offers major operators here in Canada and internationally the opportunity to scale up easily, efficiently and sustainably with our highly energy efficient 400G capabilities.”

Now deployed across major spans of Bell’s 17,000 km fibre infrastructure, 400G service will continue to grow nationally in the coming months. 400G technology increases fibre capacity using less network hardware and more automation to deliver 4x the data speed and 50% more capacity per wavelength. Ciena’s innovative WaveLogic 5 Extreme technology reduces energy usage, equipment footprint and overall system complexity, allowing service providers to create more sustainable, greener networks.

“The global shift to 400G is happening and Bell Canada is leading the way by evolving its network to support the insatiable and often unpredictable network demand driven by the cloud, streaming video and more,” said Bruce Hembree, Vice President and General Manager for the Americas at Ciena. “With WaveLogic 5 Extreme, Bell can offer new, high bandwidth 400G services to carrier and content provider customers between key points of presence across Canada and into the US.”

Bell’s wavelength service provides a reliable, secure fibre optic network for the transport of voice, data and video. By moving to 400G wavelength service, Bell is supporting the accelerated adoption of bandwidth-hungry services and applications that require fast, high capacity, low-latency connections.
