An angle-adjustable fc connector assembly and assembly method thereof

Abstract

The invention relates to an angle-adjustable FC connector assembly and an assembly method thereof. The assembly includes an outer ferrule, a ferrule, a middle connection assembly, a tail sleeve, a protective sleeve and a polarization-maintaining optical fiber. The polarization-maintaining optical fiber passes through the protection In the bushing, and one end of the protective sleeve extends into the boot from the end of the boot away from the middle connecting component, and connects with one end of the ferrule after passing through the middle connecting component, and the other end of the ferrule extends into the outer ferrule. The outer ferrule is engaged with the other end of the middle connecting component, and the outer ferrule and the middle connecting component can rotate relatively, and the surface of the outer ferrule is provided with a positioning key. The invention adjusts the relative rotation of the outer ferrule and the middle connecting component to adjust the angle between the positioning key on the outer ferrule and the panda eye of the polarization-maintaining optical fiber, the angle error is small, and the extinction ratio is guaranteed to meet the requirements and the FC connector Excellent performance, simple structure, solves the problems of low efficiency when assembling polarization-maintaining optical fibers into FC connectors, and the problem that the protective sleeve cannot completely protect the optical fibers, which is beneficial to prolonging the service life.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an angle-adjustable FC connector assembly and an assembly method thereof. Background technique [0002] With the rapid development of optical communication technology, polarization maintaining optical fiber is widely used in various fields of national economy such as aerospace, aviation, navigation, industrial manufacturing technology and communication. [0003] Polarization-maintaining fiber transmits polarized light. In practical application scenarios, it will be connected with FC connector in most cases. The extinction ratio is its most important performance index. In order to obtain the maximum extinction ratio, the panda eye of polarization-maintaining fiber needs to be connected with FC connector. The positioning key is at a specific angle (0° or 90°), the smaller the error of the angle, the better the extinction ratio index. [0004] In the prior art, ...
