The full name of MEMS VOA is Micro-Electro-Mechanical Systems Variable Optical Attenuator. VOA is commonly used in optical power equalization in optical fiber communication systems. In various technical solutions, MEMS VOAs have the advantages of small size, low cost, and easy fabrication. There are two types of MEMS VOAs most commonly used: MEMS Shutter type, which is usually driven by thermal effect, and MEMS micromirror type, which is usually driven by electrostatic force. #MEMSVOA #MEMS #VOA
