High Power Double Clad 1940nm Polarization Insensitive Optical Isolator
    High Power Double Clad 1940nm Polarization Insensitive Optical Isolator is a fiber passive component built with double
cladding singlemode 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. 
The optical power can be up to 10W CW upon request, if need pulse type please contact us to confirm.
