Product Details

The 1430, 1440, 1450, 1460nm 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 and low insertion loss. The optical isolators are commonly used to protect lasers or amplifiers against back-reflected light.
