Description

technical field [0001] The invention relates to the technical field of optical fiber optical path coupling, in particular to a multi-channel optical fiber synchronous automatic coupling device. Background technique [0002] At present, as a core component in the field of optical communication, the coupling effect of optical integrated components and optical fibers in optical modules greatly affects the strength and quality of optical signals, and thus becomes one of the key factors affecting information transmission. [0003] At present, there are two methods of optical coupling between optical devices and transmission fibers in optical modules: active coupling and passive coupling. The process of the active coupling method is: fix the laser as the light source on the PCB board, then control the laser to emit light, use the coupler adjustment to change the spatial position of the optical lens module used as the optical transmission path device, and detect the light passing t...
