Abstract: This application provides a wavelength-division multiplexing device and a communications device. The wavelength-division multiplexing device may include a fastener, optical fibers, a filter, and a lens. The fastener is provided with an optical fiber positioning hole and a filter mounting groove, the filter mounting groove is disposed on a side of a tail end that is of the optical fiber positioning hole and that is away from an opening of the optical fiber positioning hole, and the filter mounting groove and the tail end of the optical fiber positioning hole are spaced apart. The optical fiber may be installed in the optical fiber positioning hole, the filter may be installed in the filter mounting groove, and the filter may transmissively transmit or reflect light rays emitted from the optical fiber.
