Single-transmitting and single-receiving optical module device

The utility model relates to a single-transmitting single-receiving optical module device, which comprises a transmitting end device, a receiving end device, a buckle and a shell, a transmitting-receiving limiting clamping groove is arranged in the shell, the transmitting end device and the receiving end device which are arranged in the shell are limited in the horizontal direction by the transmitting-receiving limiting clamping groove, the buckle is arranged in the shell, and the buckle is arranged in the shell. The buckle limits the transmitting end device and the receiving end device in the vertical direction. According to the utility model, through the dual limiting of the transceiving limiting clamping groove and the buckle, the three-dimensional limiting of the transmitting end device and the receiving end device is realized, so that the transmitting end device and the receiving end device are stable and do not shake, the receiving and transmitting accuracy is improved, and meanwhile, the structure is s
