Abstract

The invention relates to a wavelength division multiplexing device, which comprises a primary wavelength division component, a primary optical filter group, a secondary wavelength division component and a secondary optical filter group. The primary wavelength division component is provided with a first light entering surface and a first light emitting surface; the primary optical filter group is provided with a plurality of primary optical filters capable of transmitting light with corresponding wavelengths, and pretreated light enters the primary wavelength division component through the first light entering surface and is partially transmitted through the primary optical filter group arranged on the first light emitting surface; the secondary wavelength division component is provided with a second light emitting surface and a second reflecting surface opposite to the second light emitting surface; and the secondary optical filter group is provided with secondary optical filters corresponding to the primary optical filters in number, and light transmitted by the primary wavelength division component enters the secondary wavelength division component, is partially transmitted and partially reflected by the corresponding secondary optical filters and is reflected out of the secondary wavelength division component through the second reflecting surface. A multi-stage wavelength division structure is adopted, light of different wavelengths in the pretreated light can be accurately stripped without using an MWDM film with higher cost, so that the production and use costs are reduced.

Description

technical field [0001] The present application relates to the field of optical technology, in particular to a wavelength division multiplexing device. Background technique [0002] In the field of optical communication, the function of optical wavelength division multiplexing (WDM) technology is to multiplex optical signals of different wavelengths into the same optical fiber for transmission at the transmitting end, and then separate the optical signals of different wavelengths at the receiving end, so that Save and make full use of optical fiber communication resources during transmission. As the core device of optical wavelength division multiplexing technology, optical wavelength division multiplexer has been irreplaceable. With the development of 5G technology, people's demand for communication data transmission capacity continues to increase, and the development of wavelength division multiplexing systems is also constantly introducing new ones, from the original CWDM...
