Description
895nm PM 3-port Optical Circulator
895nm PM 3-port Optical Circulator is a fiber passive component built with TGG crystal, 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 Fiber Optic Sensor, Fiber Laser and Coherent Detecting field. If need higher power version please tell us to confirm.
