Kilomega fiber transceiver

The utility model relates to the field of fiber communication and provides a kilomega fiber transceiver which has low cost and realizes in-band network management. The utility model comprises a photoelectric converting unit, a state monitoring module, an in-band information management receiving and transmitting module and a data processing module, wherein the photoelectric converting unit is composed of a light receiving and transmitting integrated module, a forwarding chip, a cable connecting head and an isolating transformer; the state monitoring module is used for monitoring and controlling the working state of the photoelectric converting unit; the in-band information management receiving and transmitting module is connected with the state monitoring module and is used for receiving and transmitting management information lower than kilomega service rate; the data processing module is connected with the in-band information management receiving and transmitting module between the forwarding chip and the light receiving and transmitting integrated module, and is used for managing information, receiving and transmitting service data. The kilomega fiber transceiver can be directly used as a far-end kilomega fiber transceiver. When the kilomega fiber transceiver is used as a local-end kilomega fiber transceiver, a bus interface module connected with the state monitoring module needs adding.
