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)
