1120nm PM 3-port Optical Circulator
    1120nm Polarization Maintaining (PM) 3-port Optical Circulator is a fiber passive component built with PM 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 Laser System, Fiber Optic Sensor and Coherent 
Detecting field.
