Single Mode (Cylindrical Ø5.5)
Single mode MEMS VOA (Variable Optical Attenuator) utilizes advanced micro-electro-mechanical system (MEMS) technology. By rotating MEMS mirrors, it precisely controls the optical coupling between input and output fibers, achieving accurate attenuation levels. Our VOA comes in two variants with different default states: Bright and Dark. The Bright variant has the lowest loss state at 0V, while the Dark variant achieves the lowest insertion loss at a voltage range of 4.5-5V. Encased in a compact package, our VOA ensures highly reliable, durable, and long-lasting operation.
Features

- Compliant with Telcordia GR-1221 and RoHS requirements
Applications
- Distributed power balancing in OADM, multiplexers/DMUX, band equalizers, and channel equalizers
- Power adjustment in EDFA (Erbium-Doped Fiber Amplifiers)
