Broadband Access
Bell Canada paves its 40G networking path
Deploys Nortel optical solution to stay ahead of broadband demand
by Telecommunications staff
Not long after it announced its intention to extend its FTTN broadband network to Multi Dwelling Units (MDUs) throughout its service territories, Bell Canada is moving to ensure its backbone network can handle the consumer’s growing bandwidth appetite.
Of course, Bell’s increased broadband drive will require a higher capacity network backbone. To ensure that it can continue to support more high bandwidth services, Bell will deploy Nortel’s 40 Gbps Adaptive Optical Engine. By going to 40 Gbps, the Canadian claims it will be able to double the current network bandwidth by 4X within Bell's Montreal-New York, Toronto-Chicago and Toronto-Montreal traffic corridors.
Looking at as a future-proof investment, the new network will give Bell more bandwidth in its backbone network, ensuring support for more customers and higher access speeds down the road.
"With Nortel's 40G solution as part of our network backbone, we continue to expand the leading-edge technology that allows us to deliver a robust Internet experience to Canadian consumers and businesses," said Kevin Crull, president of Bell Residential Services.
Nortel's solution will enable 40G transmission to co-exist within Bell's current 10G network to carry vast amounts of information across the network. Bell claims that by deploying Nortel’s 40 G system it can gain considerable savings because it can use the existing infrastructure as there is no need for Bell to deploy new fiber or alternate solutions for the metro and long haul parts of the network.
The foundation of the solution lies in Nortel's ability to allow carriers like Bell to upgrade existing 10G networks to a 40G solution through simple plug-and-play technology components. Nortel’s solution incorporates Dual Polarization Quadrature Phase Shift Keying (QPSK) with coherent detection that allows 40G operation over a 10G network as well as advanced digital signal processing that removes all compensation requirements from the network, along with their associated capital and operational expenditures.
This solution is built on the Optical Multiservice Edge 6500 and runs over Nortel’s Common Photonic Layer line system, key products that enable the migration to a more agile, adaptive, all optical network.
