MEMS VOA 100g Fiber Switch for EDFA Gain-TILT Control
Mini Size
Low PDL
Low Power Consumption
High Reliability
Corephy MEMS Variable Optical Attenuator is based on a micro-electromechanical system (MEMS) chip. The MEMS chip consists of an electrically movable mirror on a silicon support. A voltage applied to the MEMS chip causes the mirror to rotate, which changes the coupling of light between the input and output fibers of the MEMS Optical Attenuator.
Application
Receiver protection
Power Equalization in OADM
EDFA Gain-TILT Control
Power control and equalization in multi channel System
