1940nm Polarization Insensitive Optical Isolator
       1940nm Polarization Insensitive Optical Isolator is a fiber passive component built with 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.
