Abstract: An optical port shielding and fastening apparatus is configured to be installed in the optical module. The optical module includes a housing assembly and an optical component located in the housing assembly. The optical port shielding and fastening apparatus includes a fastener and an electromagnetic wave absorbing piece. The fastener is fastened in the housing assembly. The electromagnetic wave absorbing piece is fastened on a side that is of the fastener and that faces an outside of the housing assembly. A first mounting hole and a second mounting hole are correspondingly provided on the fastener and the electromagnetic wave absorbing piece. The optical component passes through the first mounting hole and the second mounting hole in sequence. This application provides an optical port shielding and fastening apparatus, an optical module, and a communications device, to resolve poor optical port shielding performance of an optical module in the related technology.
