Description
780nm High Power Polarization Insensitive Optical Isolator
780nm High Power Polarization Insensitive Optical 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 amplifier system, fiber optic sensor system to protect the light source and lower down the system optical signal noise. If need pulse type please contact us to confirm.
