August 9, 2004 Allentown, PA-- T-Networks today announced the availability of its entire Laser Integrated Modulator (LIM) product line in CWDM versions. These products will operate at the standard CWDM wavelengths from 1470 nm to 1610 nm with the same specifications as the current C-band product line. T-Networks entire 10-Gbit/sec product line, with up to 110-km transmission performance, NRZ and RZ transmission, and up to +4 dBm output power is now offered in CWDM wavelength versions.
CWDM is a standard designed to provide up to 8 channels of transmission with costs much lower than DWDM. These lower costs are realized with a combination of reduced passive optics cost due to the large tolerances in the CWDM system, and reduced active optics costs.
"We've seen significant demand for 10-Gbit/sec transmitters to upgrade existing CWDM networks for both SONET/SDH and Ethernet metro networks," said David Huff, vice president of marketing and business development. "Our product architecture allows an easy migration to CWDM wavelengths with attractive costs. Our product roadmap will also support CWDM in new form factors."
In keeping with the platform approach of the LIM, this product can be used in existing LIM designs with no modifications. The Telcordia-qualified T-Networks LIM platform, based on EAMP technology, incorporates integrated Indium Phosphide (InP) lasers, modulators, and optical amplifiers in a standard 7-pin EML-compatible package with inter-chip isolated coupling. The CWDM products are sampling now.
