MEMS MINI VOA Variable Optical Attenuator

Single Mode (Cylindrical Ø3.5)

Our single mode MEMS MINI VOA is based on micro-electro-mechanical system (MEMS) technology. The MEMS chip consists of an electrically movable mirror on a silicon frame. By applying voltage to the MEMS chip, the mirror rotates, altering the optical coupling between the input and output fibers of the MEMS VOA.

Features Proven MEMS durability and reliability Ultra-compact size Compliant with Telcordia GR-1073-CORE and RoHS requirements Direct voltage control Applications Distributed power balancing in OADM, multiplexers/DMUX, band equalizers, and channel equalizers Input power adjustment in EDFA (Erbium-Doped Fiber Amplifiers) Schematic Diagram Optical Specifications
