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.
