9 December 2003 Quebec City, Canada Lightwave -- TeraXion Inc., a developer of advanced optical components for high-speed optical networks, today announced that its ClearSpectrum dispersion compensation module has successfully completed rigorous environmental tests that correspond with Telcordia GR-1209 and GR-1221 guidelines. These tests are required by system vendors as a generic proxy to ensure reliability of passive components.
"The ClearSpectrum-DCM has been approved for use by a number of system manufacturers," reports Erick Pelletier, vice president sales and marketing at TeraXion. "With the reliability of our device now proven, customers have indicated that they will move forward in deploying our solution."
"The successful completion of these tests clearly establishes fiber Bragg gratings as a viable commercial dispersion compensation technology," adds Martin Guy, chief technology officer at TeraXion. "The exceptional results we've achieved demonstrate TeraXion's commitment to developing innovative and reliable chromatic dispersion management solutions."
Chromatic dispersion compensators are used in optical networks to reduce the accumulated dispersion in optical signals carrying information. TeraXion's fiber Bragg grating-based dispersion compensators are meant to complement and even replace current solutions using dispersion compensating fiber, which is known to have limited performance in many applications. The ClearSpectrum-DCM is the ideal solution to correct residual dispersion slope in long-haul networks or as an in-line alternative to DCF where size or insertion loss is a concern, say company representatives.
