Nortel 40G Optical Solution Enables TDC to Meet Skyrocketing Bandwidth Demands Across Europe

New Nortel Technology Provides Industry’s Most Cost-Effective Solution.

COPENHAGEN – High-bandwidth consumer applications like Internet video, the increase in the international popularity of social networking sites like Facebook and My Space, combined with new, advanced business services are creating increasing demands that are stressing network capacity worldwide. TDC, Denmark’s leading provider of communications solutions, has selected Nortel* [NYSE/TSX: NT] to deliver a 40G-ready, next-generation optical network across Europe that will provide four times the bandwidth of their current network to meet these escalating demands and provides a technology path to deliver tomorrow’s networking speeds of 100G.

TDC is deploying its new adaptive all optical solution (see companion announcement, Nortel Meets Bandwidth Explosion with New, Revolutionary 40G to 100G Optical Solution) initially to carry TDC European network traffic across the United Kingdom, the Netherlands and Germany. With this solution TDC can support industry-standard 10G services today as well as next-generation 40G services using Nortel 40G/100G Adaptive Optical Engine technology. TDC will be testing 40G products and services with the intent of launching 40G services in late 2008 due to a strong market demand. At the same time, the deployment provides TDC with a clear technology path to 100G.

“The 40G capability preserves our investment in our fibre plant that enables us to meet increasing bandwidth needs easily and also helps us meet the needs of our customers,” said Morten Bangsgaard, vice president, TDC Fixnet Nordic. “Nortel’s solution will allow us to leverage adaptive optical technologies to save both capital and operational expenses and to easily expand our services across Europe.”

“Nortel’s solution is vital for carrier customers like TDC which are taking a forward-looking approach to building out their next-generation networks,” said Philippe Morin, president, Metro Ethernet Networks. “The ability to dramatically increase bandwidth and simplify operations is of keen interest for carriers. With the increasing prevalence of devices that can and should be connected to the network, as part of the coming mega-trend of Hyperconnectivity, the demands on networks can only continue. The modern network must meet the requirements of today as well as offering the most logical path to ensure their networks are future-proof.”

The TDC optical network comprises the Optical Multiservice Edge 6500 convergence platform and the Common Photonic Layer (CPL). This agile network solution allows service providers to deliver high-growth, high-bandwidth broadband services with low deployment and operational costs.

The solution features Nortel’s unique 40G/100G Adaptive Optical Engine technology that leverages the full value of Reconfigurable Optical Add/Drop Multiplexing (ROADM) for all optical networking with its integrated dispersion compensation capabilities. 10G and 40G transponders allow information-carrying lightwaves to be transmitted beyond 2000km, nearly twice as far as competing approaches, without breaking down. This requires less equipment to plan for, deploy, and maintain.

Nortel Optical Network Manager will provide the required operations administration and management for the network and together with advanced network planning tools, will provide the ability to build and operate the network and management of services.
