Single Fiber Bidirectional Optical Circulator
Circulator realizes non-reversible optical transmission, which guides the reverse transmission of light, separates it from the forward transmission of light in space, and outputs it from another port. It can be used with WDM MUX module and DEMUX module to realize single-fiber bi-directional transmission and save fiber resources.
