Problems solved by technology

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

Abstract

The invention discloses a novel four-piece optical fiber coupling alignment table and a use method thereof. The coupling alignment table comprises a coupling table bottom plate and a first XY axis adjusting table, a first Z axis adjusting table and a second XY axis adjusting table which are arranged on the coupling table bottom plate, and an insertion core assembly clamping tool is arranged on thefirst XY axis adjusting table; a TO CAN clamping tool is arranged on the first Z-axis adjusting table; a second Z-axis adjusting table is arranged on the second XY-axis adjusting table, and a shell clamping tool is arranged on the second Z-axis adjusting table. Compared with the prior art, the beneficial effects of the wave absorber are that the device can achieve the simultaneous adjustment of the ferrule assembly, the housing assembly (lens), the transition ring and the TO CAN, can achieve the three-dimensional movement of the housing (lens), the two-dimensional movement of the ferrule assembly and the one-dimensional movement of the TO CAN, can achieve the optimal coupling effect when a coupling optical path has polarized light, and achieves the maximization of 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 ...
