Description
1760nm High Power 3-port Polarization Insensitive Optical Circulator
1760nm High Power 3-port Polarization Insensitive Optical Circulator is a fiber passive component built with faraday 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 Amplifier System, Fiber Optic Sensor and Testing System field. The handling power can be up to 10W CW.
