4 Ports Optical Circulator

1.The 4 ports optical circulator is a compact high performance lightwave component that transmits the incoming signal from port 1 to port 2,the 2nd signal from port 2 to port 3 and the 3 rd signal from port 3 to port 4.The component provides high isolation,low insertion loss,high extinction ratio,and excellent environment stability.
2.It is a special kind of fiber optic components,with single fiber bidirectional transmission function.This function is often combined with optical fiber grating and other reflection components used in DWDM system.Dual-way communication system,the dispersion compensation,EDFA application and OTDR measurement.
