| 850nm PM 4-port Optical Circulator | |||||||||||||||
| 850nm 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 Fiber Optic Sensor, Fiber Laser and Coherent Detecting field. High Power version is available upon request | |||||||||||||||
