Abstract

The embodiment of the invention relates to the technical field of optical communication, specifically relates to an optical module, and is used for solving the problem that in the prior art, a lens is displaced at the position of a base due to the influence of glue, and the offset of the optical path through the lens occurs. The optical module comprises a base, a fixing part, a lens, and a laser, the fixing part is welded on the base and is mainly formed by metal, the lens is fixedly connected with the fixing part, the laser is arranged on the base, and the optical path which optical signals emitted by the laser belong to passes through the lens.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] Wavelength Division Multiplexing (WDM for short) technology refers to the simultaneous transmission of two or more optical signals of different wavelengths in the same optical fiber. At the sending end, two or more optical carrier signals of different wavelengths can be combined through a multiplexer (also known as a multiplexer, Multiplexing in English), and coupled to the same optical fiber in the optical line for transmission; At the receiving end, two or more optical carrier signals of different wavelengths can be separated through a multiplexer (also called a demultiplexer, Demultipexer in English), and then further processed by an optical receiver to restore the original signal. [0003] In the prior art, a typical wavelength division multiplexer uses a separate lens to couple the light emitted by multiple semi...
