OPTICAL DEVICE AND OPTICAL COMMUNICATION APPARATUS

An optical device and optical communication equipment are applied to an FTTR scene, and the optical device comprises a cover body, a circuit board, a baffle plate and a bidirectional optical assembly. The cover body and the light transceiving assembly are arranged on the same surface of the circuit board, the cover body covers at least part of the bidirectional light assembly, and a notch is formed in the side wall of the cover body. The baffle plate is fixed on the surface of the circuit board and shields at least part of the gap, and the baffle plate and the at least part of the gap jointly form a channel for optical fibers of the bidirectional optical assembly to pass through. After the cover body and the circuit board are assembled, the baffle shields the part, close to the circuit board, of the notch and leaves a part of space to form a channel for optical fibers to penetrate through, so that the sealing performance between the cover body and the circuit board is improved to the maximum extent, in addition, the baffle is arranged on the surface of the circuit board, a through hole does not need to be formed in the circuit board, the sealing performance of the circuit board is further improved, and the cost is reduced. The electromagnetic radiation capability of the optical device can be reduced, and the electromagnetic shielding effectiveness of the optical device is improved.
