Product Details

The 1450nm High Power Polarization Independent (Polarization Insensitive) 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, low insertion loss and high power handling . The optical isolators are commonly used to protect lasers or amplifiers against back-reflected light.
