The Micro-Electromechanical System (MEMS) optical switches in power systems may be affected by optical control signals during fiber switching. which may cause damage to Optical Time-Domain Reflectometer (OTDR). In order to solve this problem. this paper proposes a method to optimize the switching path of MEMS optical switches in power systems. https://www.mariameetsanna.com/product-category/neon-blue/
