|
1550nm 3-port Multimode Optical Circulator is a fiber passive component built with MM fiber, 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 WDM System, Fiber Optic Sensor and Testing System field. The multimode fiber can be 50/125 or 62.5/125 fiber. |
