Plastic fiber optic connectors are used for arc protection, which means that in the arc protection device of the power system, plastic fiber optic connectors are used to achieve the connection and transmission of optical signals between arc sensors and main control units, expansion units and other devices. Plastic fiber optic connectors play a key role in this process. They efficiently and stably transmit the optical signals collected by the arc sensor to the processing unit of the protection device through plastic optical fiber for analysis and judgment, and then trigger corresponding protection actions, such as sending trip signals, to quickly remove faults and ensure the safe operation of the power system.AFBR-S10PS010Z AFBR-S10PS011Z
