Communication device and communication apparatus

The communication device and the communication equipment are applied to an FTTR scene, the communication device comprises a cover body arranged on the surface of a circuit board, and the cover body and the circuit board form an accommodating space; the bidirectional optical transceiving assembly comprises a shell, a fixing seat, a transmitting optical assembly and a receiving optical assembly, the transmitting optical assembly and the receiving optical assembly are installed on the shell, the shell, at least part of the fixing seat, the transmitting optical assembly and the receiving optical assembly are all located in the containing space, one end of the fixing seat is fixedly connected with the circuit board, and the other end of the fixing seat is fixedly connected with the shell. The bidirectional optical transceiver assembly is shielded through one cover body, and compared with a double-sided shielding cover, the cost is reduced, and the assembly is simple. The bidirectional optical transceiver assembly is fixed by the fixing seat mounted on the circuit board, the acting force of the cover body on the fixing seat is absorbed by the circuit board, a half-moon plate for fixing the bidirectional optical transceiver assembly in the double-sided shielding cover is removed, the seesaw effect of the double-sided shielding cover is effectively avoided, and the optical power change of the communication device is optimized.
