Product Details

The 1310 1480 1550 nm Polarization dependent (Polarization sensitive) 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 PDL and low insertion loss. These Polarization dependent isolators are built by non-PM fibers.
