The bidirectional optical fiber receiving-transmitting circuit in the invention comprises a luminescence module, a first optical processing module, a driving module, a modulation module, a wavelength-division multiplexing module, a second optical processing module, a photoelectric conversion module and an amplification module; at a transmitting terminal, an electrical signal is sent to a remote receiving device via an optical fiber after being converted into an optical signal; and at a receiving terminal, the optical signal received by the optical fiber is output after being converted into the electrical signal. The conversion and the transmission of a high-speed signal are implemented by the bidirectional optical fiber receiving-transmitting circuit on one optical fiber by adopting a silicon photonics technology, the cost is low and the yield rate is high; and thus, the problems that the existing receiver-transmitter has low yield rate and high cost, and the improvement of a transmission rate of the fiber to the home is affected due to the high cost are solved.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to a bidirectional optical fiber transceiver circuit and a bidirectional optical fiber transceiver. Background technique [0002] With the development of Internet technology, optical fiber communication has become the main communication method of the existing Internet, and in optical fiber communication, the most core is the transceiver for transmitting optical signals. Among them, the main working process of the transceiver is: at the transmitting end, the transmitter converts the electrical signal into an optical signal and provides sufficient transmission power, and then transmits the information to the remote end where the receiver is located. The reception converts the received optical signal into an electrical signal, and completes the transmission process of electronic information through the optical medium. [0003] At present, the optical de...
