MEMS Variable Optical Attenuator
Key Features
- Low insertion loss
- Available in normally transparent and normally opaque
Primary Applications
- Power equalisation in multi-channel, optically amplified networks
- Gain-tilt control in erbium doped fibre amplifiers (EDFA)
- Dynamic gain/channel equalisers (DGE/DCE) in DWDM/CWDM networks
- Reconfigurable optical add/drop multiplexer (ROADM) power balancing
- Receiver protection/switching during transmitter enabling
