780±30nm PM 4-port Optical Circulator
          780±30nm PM 4-port Optical Circulator is a fiber passive component built with TGG crystal, which can change signal light transmission path, one signal can be delivered from Port 1 to Port 2, the second signal light from Port 2 to Port 3, the third signal from port 3 to port 4, the high isolation can block the back reflection light. It's widely used in Quantum Communication, Fiber Laser and Coherent Detecting field. High Power version is available upon request
