Title:
WAVELENGTH-DIVISION MULTIPLEXING DEVICE AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/213810
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides a wavelength-division multiplexing device and a communication device. The wavelength-division multiplexing device may comprise a fixing member, an optical fiber, a filter, and a lens. The fixing member is provided with an optical fiber positioning hole and a filter installation slot, the filter installation slot is disposed on the side of the end of the optical fiber positioning hole distant from the aperture of the optical fiber positioning hole, and the filter installation slot and the end of the optical fiber positioning hole are arranged at an interval. The optical fiber may be installed in the optical fiber positioning hole, the filter may be installed in the filter installation slot, and the filter may transmit or reflect light emitted from the optical fiber. In addition, a lens disposed between the optical fiber and the filter may be used to collimate the light emitted from the optical fiber, or to converge the collimated light and then input same into the optical fiber. The wavelength-division multiplexing device aligns the optical fiber and the filter by means of the alignment setting between the optical fiber positioning hole and the filter installation slot, which may effectively improve the assembly efficiency of the wavelength-division multiplexing device, and may thus improve the production efficiency of the communication device.
