DuPont Photonics' integrated VOA array passes Telcordia qualifications

August 18, 2004 Wilmington, DE, and Wilmington, MA --DuPont Photonics Technologies, provider of integrated optical components and a wholly owned subsidiary of DuPont, today announced that its iVOA family of integrated variable optical attenuators (VOAs) has successfully completed all reliability tests based on Telcordia GR-1221-CORE and GR-1209-CORE guidelines. The iVOA has met or exceeded all relevant Telcordia standards.

August 18, 2004 Wilmington, DE, and Wilmington, MA -- DuPont Photonics Technologies, provider of integrated optical components and a wholly owned subsidiary of DuPont, today announced that its iVOA family of integrated variable optical attenuators (VOAs) has successfully completed all reliability tests based on Telcordia GR-1221-CORE and GR-1209-CORE guidelines. The iVOA has met or exceeded all relevant Telcordia standards.

"We are extremely pleased with the VOA performance achieved during these Telcordia tests," asserts Dr. Louay Eldada, chief technology officer and vice president of engineering at DuPont Photonics. "The iVOA exceeds the Telcordia standard by a big margin in all the tests, including mechanical vibration and shock, thermal cycling and shock, and operation at high temperature and humidity levels. These results, together with the results from our extreme temperature, optical power, and electrical power tests, clearly demonstrate the robustness of our design and the reliability of our products."

Based on DuPont's planar lightwave circuit (PLC) platform, the iVOA provides what the company contends is the most cost effective VOA solution for power balancing, power control, and dynamic gain equalization. The iVOA family includes both normally transparent and normally dark attenuators of up to 40 channels. DuPont's VOA operates across the C and L bands with low insertion loss, low polarization dependent loss (PDL), low wavelength dependent loss (WDL), low temperature dependent loss (TDL), low power consumption, high dynamic range, and simple electronic control. In addition, the VOAs have no moving parts and are stable to mechanical vibration and shock. The iVOA products are generally available now.
