High Power 1940nm PM Optical Isolator
      High Power 1940nm Polarization Maintaining Optical Isolator is a fiber passive component built with PM 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.
