The invention discloses a novel four-piece optical fiber coupling and alignment platform and its use method. The coupling and alignment platform includes a coupling platform bottom plate and a first XY-axis adjustment platform, a first Z-axis adjustment platform and a first Z-axis adjustment platform arranged on the coupling platform bottom plate. The second XY axis adjustment table, wherein: the ferrule assembly clamping tool is set on the first XY axis adjustment table; the TO CAN clamping tool is set on the first Z axis adjustment table; the second XY axis adjustment table is set on the second The second Z-axis adjustment table is provided with a shell clamping tool on the second Z-axis adjustment table. Compared with the prior art, the positive effect of the present invention is that the present invention can simultaneously adjust the ferrule assembly, housing assembly (lens), transition ring, and TO CAN four components, and the housing (lens) can move three-dimensionally. The ferrule assembly can move two-dimensionally, and the TO CAN can move one-dimensionally, so as to achieve the best coupling effect even when the coupling optical path has polarized light, and to maximize power efficiency.
Description
technical field [0001] The invention relates to a novel four-piece optical fiber coupling alignment table and its application method. Background technique [0002] The optical device has a lens structure, which converts the optical path through the lens to achieve the required size and photoelectric index. In the three-piece coupling, when the precision of the structural parts is insufficient and the assembly error causes the optical path to not be completely parallel, and there is a deviation of more than 0.1mm, it is difficult for the lens to adjust the optical path, which will cause the optical path coupling efficiency to decrease or even fail to meet the requirements. power requirements. To solve this problem, a four-piece coupling is required to adjust the optical path so that the optical path passes through the center of the lens to achieve the best coupling efficiency. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the ...
