MAY 2, 2007 -- MRV Communications Inc. (search for MRV) today announced the availability of two new cards for the LambdaDriver (search for LambdaDriver) WDM systems. These new WDM cards combine 10-Gigabit Ethernet (10-GbE) wavelength and dispersion tunability for distances up to 350 km and are remotely reconfigurable, reducing deployment and operational time and costs while increase reliability and scalability, say company representatives.
With built-in tunable dispersion compensation together with tunable 10-GbE wavelengths, the LambdaDriver TM-DXFP20T and TM-DXFP35T cards enable ease of use, cost savings on sparing, and network planning simplification to help streamline DWDM network deployments, says MRV. The new tunable cards support per wavelength fine-tuning of dispersion compensation, allowing dispersion balancing over long distance WDM networks. The new tunable WDM 10-GbE cards can be reconfigured remotely with MRV's WDM management system to improve response time and reduce maintenance cost. In a tunable WDM long haul network application, these transponders reduce the need for downstream dispersion compensation--from every 90 km to as much as 350 km, says the company.
The dispersion compensation, combined with wavelength tunability across the entire WDM C-band, provides advantages for both metro and long haul networks. Carriers can deploy metro tunable WDM networks without having to employ standalone dispersion compensation capabilities. In a long haul network application, MRV's new tunable WDM 10-GbE transponders enhance the ability of carriers and enterprises to evolve their networks, deliver new services, and implement tunable WDM networks that are easy to use.
"The new integrated WDM tunable cards represent a significant step in next-generation reconfigurable 10-GbE transport, as they integrate multiple advanced features into a single world-class platform," contends Noam Lotan, president and CEO of MRV Communications. "This integrated LambdaDriver solution takes our optical innovation strategy to a higher level and provides a tunable WDM 10-GbE solution to answer our customers' increasing demands for greater scalability, more flexibility in their WDM networks, and more efficient use of OPEX."
MRV's integrated tunable WDM cards support STM64/OC-192 (9.955 Gbits/sec) and 10-GbE protocols. They can be remotely set to any 50-GHz spacing DWDM waves on the ITU-T grid (G.694.1) in C-band. L-band tunability also is available.
According to the company, the WDM platform delivers versatile tunable transponders and muxponders for access, cores, and enterprise applications, while enhancing the ability of carriers and enterprises alike to tune their WDM optical networks and deliver enhanced new services. The new 10-GbE tunable modules can be used throughout the LambdaDriver WDM family, including the compact LD400, the LD800, and LD1600 modular chassis.
The LambdaDriver tunable 10-GbE WDM cards, TM-DXFP20T and TM-DXFP35T, are now available.
