Description
1550nm 4-port Polarization Insensitive Optical Circulator
1550nm 4-port Polarization Insensitive Optical Circulator is a fiber passive component built with SM fiber, which can change signal light transmission path, the signal can be delivered from Port 1 to Port 2, Port 2 to Port 3, Port 3 to Port 4, the high isolation can block the back reflection light. It’s widely used in WDM System, Fiber Optic Sensor and Coherent Detecting field.
