Optiviva upgrades its MEMS variable attenuator
July 26, 2005 Guangzhou, China and Los Altos, CA -- Optiviva has announced the general availability of its patent-pending MVOA-300 MEMS variable attenuator (VOA). The company says the Telcordia 1209- and 1221-compliant devices' assembly technique improves upon earlier versions of the product, by incorporating TO-46 packaging with the company's proprietary hermetic sealing technology.
Designed for use in ROADM, V-Mux, OXC, and EDFA optical modules, the MVOA-300 VOA offers blocking (maximum attenuation at power off)and non-blocking (minimum attenuation at power off) configurations. Applications include channel equalization, gain-tilt control, and transmission protection.
