1550nm High Power PM Optical Isolator 1-10W
Product Details
The 1550nm High Power Polarization Maintaining (PM) Optical Fiber Isolator is an in-line miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It's built with PM Panda fiber and designed to maintain the polarization of the input light with high extinction ratio. The PM isolators are commonly used to protect lasers or amplifiers against back-reflected light. Dual stage isolator means two singe stage isolators are packaged into one compact housing. High power up to 10W availible upon request.
