Proximion Demonstrates Channelized 40Gbps Dispersion Compensation Module

San Diego, CA - At the 2008 Optical Fiber Communication Conference and Exposition (OFC), Proximion Fiber Systems AB announced the demonstration of its new 40Gbps dispersion compensation module (DCM-ITU). DCM-ITU is a cost-effective dispersion compensation solution with a small form factor. Unlike competing alternatives, the DCM-ITU's wider bandwidth has superior performance due to low group delay ripple (GDR). Highly suitable for cascaded applications, DCM-ITU operates in 40Gbps as well as 10Gbps formats and over the entire C-band.

DCM-ITU supports bandwidth consuming modulation formats at 40Gbps. With bandwidth that is wider than 42GHz, the solution efficiently enables 100GHz channel spacing. (Proximion also provides [optional basis] channelized solutions with ITU-offsets of +33GHz, +50GHz and +66GHz from the ITU-grid, suitable for submarine applications, e.g. slope compensation). Unique and proprietary Fiber Bragg Grating (FBG) manufacturing technology allows Proximion to produces high-performance dispersion compensation modules with the advantages of having no non-linear effects, no latency and having a very low signal and power loss compared to the alternative of traditional dispersion compensating fibers (DCFs). Thus, DCM-ITU is ideally suited for metropolitan and regional networks.

"The DCM–ITU is perfect for those customers that do not need 50-GHz channel spacing but still want to run 10bps and 40Gbps systems in a cost-effective way," says Stefan Ekman, CEO at Proximion. "The importance of dispersion management is increasing in all parts of the network. We are already an established supplier to a number of systems vendors for applications up to 40Gbps."

DCM-ITU is currently available on volume basis. Proximion is showcasing DCM-ITU at OFC on February 26 – 28, Booth Number 3619.
