Description

technical field [0001] The invention relates to wavelength division multiplexing / demultiplexing technology, in particular to a multiplexing / demultiplexing optical device and a method for realizing optical path multiplexing / demultiplexing. Background technique [0002] Wavelength division multiplexing (WDM, Wave-length Division Multiplexing) is to combine two or more optical carrier signals of different wavelengths at the sending end through a multiplexer (Multiplexer), and couple the combined optical carrier signals to the optical line. In the technology of transmission in the same optical fiber, optical carrier signals of different wavelengths carry different information; at the receiving end, the demultiplexer (Demultiplexer) separates the coupled optical carrier signals of various wavelengths to separate out different wavelengths The optical carrier signal is then output to the optical receiver, which is further processed by the optical receiver to restore the original si...

AI Technical Summary

Problems solved by technology

[0009] It can be seen from the above that in the existing multiplexing / demultiplexing optical equipment, two groups of parallel selective wavelength filters are arranged in the double-sided parallel optical block, and the interval between the two parallel groups of selective wavelength filters is preset Due to the need to set the selective wavelength filter in the constant distance, and the required constant distance is small, it is easy to make the selective wavelength filter set in the double-sided parallel optical block interfere with each other, resulting in Less practical for multiplexing / demultiplexing optics
