Description
635nm PM Fiber Optic Isolator
635nm PM Fiber Optic Isolator is a fiber passive component built with TGG crystal, it allows light signal to be delivered in one forward direction and avoid the back reflection light, it’s widely used in Quantum Communication system, Fiber Laser system to protect the light source and lower down the system optical signal noise. The hgih power type is available upon request.
