Description
670nm High Power PM Fiber Optic Isolator
670nm High Power 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, Fiber Laser system to protect the light source and lower down the optical signal noise. If need pulse type please contact us to confirm.
