Problems solved by technology

UV glue is a kind of glue that can be cured quickly when exposed to ultraviolet light, but its strength is low, and then black glue needs to be cured at high temperature
During the manual operation before the black glue is cured, due to the lack of high-strength mechanical fixation among the lasers, optical lens modules and optical fibers that make up the optical path, it is very easy to cause the optical lens module to deviate from the coupling position, resulting in poor coupling effect of the optical path

Abstract

The invention discloses an optical module. The optical module includes a PCB board, an optical element arranged on the PCB board, an optical fiber coupled with the optical element through an optical lens module, and a fixed bracket, which is detachable from the fixed bracket. A connected lens holder and an optical fiber holder detachably connected to the lens holder, the fixed holder is fixed on the PCB board, the optical lens module is arranged on the lens holder, and the optical fiber is arranged on the optical fiber holder The optical element is located between the fixed bracket and the lens bracket, the fixed bracket is provided with at least two positioning components, and the lens bracket is provided with positioning components that match the fixed bracket. To achieve the corresponding positioning parts of the detachable connection. Moreover, the coupling of optical paths is realized through mechanical fixation between multiple brackets, which simplifies the process, reduces the coupling cost, and improves the coupling consistency and accuracy.

Description

[0001] This patent application is a divisional application with the application number 2013101186130, the application date is April 8, 2013, and the invention title is "Optical Module and Its Optical Path Coupling Method". technical field [0002] The present invention relates to optical communication technology, in particular to an optical module. Background technique [0003] In existing optical communication technologies, optical signals are used as information carriers for high-speed, long-term, and reliable information transmission. As a core component in the field of optical communication, the coupling effect between the optical element and the transmission path (optical fiber) in the optical module greatly affects the optical signal strength and signal quality, and becomes one of the key factors affecting information transmission. [0004] At present, there are two methods of optical coupling between optical components and transmission fibers in optical modules: activ...
