LightConnect's MEMS-based variable optical attenuators pass Telcordia qualification requirements

Oct. 11, 2001--LIGHTCONNECT, Inc., a worldwide supplier of MEMS-based, dynamic components for the optical networking market, announced that its Variable Optical Attenuator Series 1000 and 2000 have successfully passed and are now qualified as having met Telcordia GR-1221 and GR-1209 guidelines.

LIGHTCONNECT, Inc., a worldwide supplier of MEMS-based, dynamic components for the optical networking market, announced that its Variable Optical Attenuator Series 1000 and 2000, based on the company's Diffractive MEMS technology, have successfully passed stringent reliability tests and are now qualified as having met rigorous environmental conditions according to both Telcordia GR-1221 and GR-1209 guidelines. The company claims their VOAs are the first MEMS-based VOAs to pass Telcordia's testing program.

In addition, LIGHTCONNECT also cycled Fast VOAs between 0 and 15 dB of attenuation over 40 billion times at elevated temperatures (85C) demonstrating a level of reliability never met by MEMS-based components before. Also, it was demonstrated that the VOAs, while operating, were not affected by mechanical shock or vibration.

The Telcordia protocols are internationally recognized standards for demonstrating the long-term reliability and performance of optical components. The protocols are also used to determine the quality of the manufacturing process. These reliability criteria are set forth in the Generic Requirements (GR) documents and measure a wide variety of mechanical, environmental and endurance factors, including stress, vibration, thermal shock, moisture resistance, damp heat, temperature cycling and other considerations.

The LIGHTCONNECT D-MEMS devices are certified for both controlled (central office and remote terminal) and uncontrolled environments. The latter consideration is especially important for devices being deployed in metro networks.
