Polarization Maintaining MEMS VOA

Product Details

fiber's Polarization Maintaining (PM) MEMS VOA is a type of optical attenuator that combinesMicro-Electro-Mechanical Systems (MEMS) technology with polarization-maintaining (PM) fiber technology. PM MEMS VOAs are essential components in modern optical communication systems, enabling precise control of light intensity and polarization, which is critical for high-performance and reliable optical networks.

Features
·Low Insertion Loss
·High AttenuationRange
·Low PDL, WDL
·Low Power Consumption

Applications
·Power management
·Receiver Protective
