Description
1310nm Multimode Fiber Optic Isolator
1310nm Multimode Fiber Optic Isolator is a fiber passive component built with multimode fiber, it allows light signal to be delivered in one forward direction and avoid the back reflection light, it’s widely used in amplifier system, fiber optic sensor system to protect the light source and lower down the optical signal noise. High power type is available upon request.
