1625nm 3-port Polarization Insensitive Optical Circulator
    1625nm 3-port Polarization Insensitive Optical Circulator is a fiber passive component built with SM fiber, which can change 
signal light transmission path, the signal can be delivered from Port 1 to Port 2, the other signal light from Port 2 to Port 3, the 
high isolation can block the back reflection light. It's widely used in WDM System, Fiber Optic Sensor and Coherent Detecting 
field. High Power type is available upon request.
