Description

technical field [0001] The invention relates to the technical field of laser coupling, in particular to a center calibration device of a laser coupling table. Background technique [0002] At the beginning of using optical fiber for optical signal transmission, it is necessary to use a laser to input the optical signal into the optical fiber. When inputting the optical signal, the output end of the laser needs to be aligned with the optical fiber to ensure that the optical signal enters the optical fiber accurately. The optical signal emitted by the laser There are usually two ways to enter the optical fiber: direct coupling and lens coupling. Direct coupling refers to directly attaching the optical fiber to the output end of the laser, while lens coupling refers to adding a lens between the laser and the lens to converge the optical signal. Then enter the fiber. [0003] However, in the prior art, the traditional coupling device is difficult to adapt to direct coupling and...
