SM MEMS VOA Attenuator, Singlemode MEMS Variable Fiber Optical Attenuators

Product Details

GLSUN's singemode MEMS Variable Optical Attenuator (VOA) is a precise and adjustable voltage-driven optical component. The key part of the component is MEMS chip; driving voltage produces electrostatic force to drive the micro-mirror on the chip, then to adjust output optical power. This SM MEMS VOA has excellent features such as compact dimension, low power consumption, fast responding, anti-shock, low WDL as well as low PDL.
