中科锐择光电提供的保偏光纤隔离器是基于在线的微光学器件,用来允许信号光正向通光,反向不通光,具有低损耗,高隔离度,高回损,该系列产品可用于光纤激光器、光纤放大器,光纤通信以及光纤传感等领域。

The Polarization Maintaining Optical Fiber Isolator is an in-line pigtailed miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It features high isolation ,high extinction and low insertion loss. It is ideal for fiber laser、fiber amplifier、fiber communication and fiber sensor.
