Abstract: The present disclosure provides an optical transceiver device including an optical assembly and at least three transceiver modules. The optical assembly has an optical fiber interface connected to an external optical fiber; each of the transceiver modules is configured to process an optical signal of a corresponding mode to send a downlink optical signal of the corresponding mode to the optical assembly, and receive an uplink optical signal of the corresponding mode provided by the optical assembly; the optical assembly is configured to perform multiplex processing on the downlink optical signal received to generate a downlink multiplexed optical signal and send it to the external optical fiber, and perform demultiplex processing on an uplink multiplexed optical signal received to obtain an optical signal of the corresponding mode of at least one of the transceiver modules. The present disclosure further provides an optical network system.
