MEMS MINI VOA Variable Optical Attenuator
Request a Quote
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)
