BT to Extend Core Network with Lucent's Optical Technology

BT awarded a major contract to Lucent Technologies to expand its core network using dense wave division multiplexing (DWDM) technology.

Pioneered by Ciena Corp., DWDM splits the light inside optical fibres into multiple channels, thereby increasing capacity.

"Lucent's DWDM system will enable us to meet the fast growing demand for voice and data services. Lucent's considerable experience in designing, building and managing high-capacity networks means we can offer our customers the sophisticated, high-speed communications they demand," said Ted Collins, transmission delivery manager at BT.

BT put the contract out to a competitive bidding tender while also extensively testing the Lucent technology. The value of the contract was not announced.

Lucent will become the main supplier to BT of high-capacity optical networking technology, and will be installing its WaveStar OLS 80G 16-channel DWDM system as part of the deal. It will also provide ITM-SC network management technology, a centralised Network Element Management system.

Lucent has already installed around 2,000 optical line systems for different organisations and claims the largest share of the $2.2 billion global DWDM market at 29 percent.
