| 摘要 |
<p>The present invention applies to the technical field of communications. Provided is a single-fiber bi-directional optical module and a passive optical network system using the single-fiber bi-directional optical module. The single-fiber bi-directional optical module comprises a transmission module, a reception module, and a coupler. The transmission module is used for transmitting a downstream optical signal having a first wavelength and a test optical signal; the reception module is used for receiving an upstream optical signal having a second wavelength, and for receiving a reverse optical signal having a first wavelength, said reverse optical signal being correspondingly generated during transmission of the test optical signal over an optical fiber network; the coupler is used for transmitting to the optical fiber network the downstream optical signal having a first wavelength and the test optical signal, and for feeding back to the reception module the reverse optical signal having a first wavelength and the upstream optical signal having a second wavelength. The single-fiber bi-directional optical module of the present invention has a simple structure, is easy to manufacture, and is low in cost.</p> |
