Optical module and manufacturing method thereof

Abstract

The invention relates to an optical module, which comprises a light emitting assembly, an optical port, an optical fiber and an optical fiber connecting part for guiding and sending laser. The laser emitted by the light emitting assembly sequentially passes through the optical fiber connecting part and the optical fiber and is emitted to the optical port, and the optical fiber is communicated withthe optical fiber connecting part; and a light path in the optical fiber connecting part is arranged in a downward inclined manner along the laser transmission direction. The invention discloses a manufacturing method of an optical module. The manufacturing method comprises three steps of S1-S3. According to the invention, the optical fiber connecting part is made into an inclined structure; theinclination angle of the light path in the optical fiber connecting part is controlled, so that a problem of small optical fiber bending radius is solved; further, the stress is reduced in a subsequent light path without a fiber coiling form; problems of optical fiber breakage, unattractive intersection of a plurality of internal optical fibers, possible damage to the optical fibers during assembly and the like due to fiber coiling in the module are solved, the conditions of optical loss and light instability caused by large-amplitude bending of the optical fibers are greatly reduced, the total working hours are reduced, the yield is improved, and the problem of no light after long-term use is solved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module and a manufacturing method thereof. Background technique [0002] With the rapid development of optical interconnection technology, the requirements for the transmission rate of communication systems are getting higher and higher, the market demand for 100G and 400G optical modules is increasing, and the requirements for cost control of optical modules are also getting higher and higher. Competition is also getting fiercer. [0003] 1X1, 1X2, 1X4, 1X8, 1X12 parallel multi-channel communication optical transmitter modules have become one of the most competitive solutions in the field of short-distance high-speed optical transmission due to their high speed and low cost.
