Ericsson and T-Com in world’s first trial for next-generation optical technology

September 26, 2006, Ericsson (NASDAQ:ERIC) and Deutsche Telekom’s fixed network unit, T-Com, have successfully completed the world’s first trial for next-generation 43Gbps optical transmission technology over a 1000km link in T-Com’s DWDM network in Germany.

Enabling 40Gbps connections between its IP core routers, this technology will allow T-Com to expand its network capacity in order to meet the rapid growth in broadband services usage.

Stefan Kindt, President Ericsson Germany, says: “Cooperation and trials with major customers such as Deutsche Telekom in areas of novel technologies are of vital interest for Ericsson. This trial has brought us a major step forward towards a common objective we share with our customers - achieving robust 43Gbps DWDM transmission over long distances at a competitive price.”

The use of 40Gbps optical transmission facilitates a cost-efficient evolution for operators towards higher optical link capacities on existing and new infrastructure.

This technology enables 40Gbps long-distance transmission over existing 10Gbps DWDM infrastructure and provides the operator with traffic growth potential of up to 6.4Tbps per fiber pair.

The trial was conducted over T-Com’s optic link between the German cities of Nuremberg and Oschatz (1047km), which is equipped with Ericsson’s WDM platform.

Ericsson’s next-generation 43Gbps optical transmission technology is based on the new modulation format return-to-zero differential quadrature phase shift keying (RZ-DQPSK). This modulation format exhibits high robustness against PMD (Polarization Mode Dispersion).

This trial highlights the benefits of the Marconi acquisition to Ericsson’s customers. Both fixed and mobile operators value having a strategic partner and a provider of end-to-end solutions - including broadband access, leading-edge microwave and optical transport networks.

Ericsson is shaping the future of mobile and broadband internet communications through its continuous technology leadership. Providing innovative solutions in more than 140 countries, Ericsson is helping to create the most powerful communication companies in the world.
