CoreOptics delivers first 111-Gbit/sec transmission over 2,400 km
MARCH 27, 2007 -- CoreOptics Inc. (search for CoreOptics), a designer and manufacturer of 10- and 40-Gbit/sec optical networking subsystems, reports having successfully demonstrated the industry's first 111-Gbit/sec transmission over 2,400 km utilizing Coherent Detection technology.
This technical trial featured transmission of 10 channels of 111 Gbits/sec at 50-GHz channel spacing over 2,400 km of standard simglemode fiber (SSMF).
"I am delighted to share the results of this very successful cooperation with CoreOptics and the Eindhoven University of Technology, as we have jointly demonstrated the feasibility of 100-Gbit/sec transmission enabling [the] next generation of wide area networks," says Bernhard Kubis, vice president of research and development at Siemens Networks (search for Siemens). "In addition to the impressive data rates and reach that we have achieved, this demonstration proved the feasibility of transmission of 100 Gbits/sec over the 10-Gbit/sec network infrastructure installed today."
CoreOptics' Coherent Detection technology is enabled by proprietary digital signal-processing techniques. This technology enables extraction and translation of additional properties of the optical signal into the electrical domain, enabling more robust transmission over longer distances and achieving higher signal quality.
"We are very pleased to have demonstrated, in partnership with Siemens and with excellent support from Eindhoven University of Technology, this truly disruptive 100G transmitter and receiver architecture that we believe is the technically and commercially most attractive answer for carriers' needs to transport emerging next-generation 100GbE clients," comments Christoph Schulien, CoreOptics cofounder and lead system architect for next-generation 40G/100G products.
The reported trial has been partly supported within the project EIBONE (Efficient Integrated Backbone) from the German Government BMBF (Bundesministerium fur Forschung und Bildung).
