Abstract

The invention relates to the field of optical communication, in particular to a wavelength division multiplexer. The wavelength division multiplexer comprises: an incident light collimator; light-emitting collimator groups which comprise a first row of light-emitting collimators and a second row of light-emitting collimators; a light splitting unit which comprises a plurality of filters with different wavelengths and a reflecting mirror; and a displacement prism group which comprises a plurality of prisms the number of which corresponds to that of the first row of light collimators, wherein the plurality of the prisms are used for guiding light emitted by part of filters in the light splitting unit to the first row of light collimators. The light-emitting collimator groups are arranged tobe the first row of light-emitting collimators and the second row of light-splitting collimators; the incident light collimator, the second row of light collimators and the light splitting unit are arranged on the same plane, part of light in the light splitting unit is guided to the first row of light collimators through the displacement prism set, the volume of the device is effectively reducedwhile the wavelength division multiplexing function is completed, the structural compactness is improved, and the wavelength division multiplexer has the advantages of being simple in structure, easyto implement, low in cost and the like.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a wavelength division multiplexer. Background technique [0002] With the development of miniaturization of communication equipment and communication modules, the miniaturization of wavelength division multiplexing devices and wavelength division multiplexing modules is also getting higher and higher. [0003] The traditional wavelength division multiplexer module is made in a larger box, using multiple three-port wavelength division multiplexers through fiber splicing, and then coiling the fiber. This traditional structure design is due to the traditional Due to the limitation of the size of the wavelength division multiplexing device and the bending radius of the optical fiber, it is difficult to further make the wavelength division multiplexer module smaller. [0004] Therefore, the existing technology still needs to be improved and developed. SUMMARY OF THE INVENTION ...
