A single-fiber bi-directional optical transceiver includes a laser diode, a photodiode, a splitter, a band filter between the splitter and the photodiode, a fiber optic connector, a first coupling lens between the laser diode and the splitter, a second coupling lens between the splitter and the fiber optic connector, and a shield plate having a run-through hole therein. The laser diode, the first coupling lens, the splitter, the second coupling lens and the fiber optic connector are coaxial and/or in series, and the photodiode, the band filter and the reflection path of the splitter are coaxial and/or in series. The shield plate is configured to stop wide-angle reflected light from being absorbed by the photodiode, while narrow-angle reflected light is isolated by the band filter. Thus, the single-fiber bi-directional optical transceiver can effectively reduce, avoid or eliminate crosstalk. |
