Angle-adjustable FC connector assembly and assembling method thereof

Abstract

The invention relates to an angle-adjustable FC connector assembly and an assembling method thereof. The assembly comprises an outer clamping sleeve, an insertion core, a middle connection assembly, atail sleeve, a protection sleeve and a polarization maintaining optical fiber. The polarization maintaining optical fiber is arranged in the protective sleeve in a penetrating manner. One end of theprotective sleeve extends into the tail sleeve from one end, far away from the middle connecting assembly, of the tail sleeve. One end of the insertion core is inserted into the middle connecting assembly and connected with one end of the insertion core after penetrating through the middle connecting assembly, the other end of the insertion core extends into the outer clamping sleeve, the outer clamping sleeve is clamped with the other end of the middle connecting assembly and can rotate relative to the middle connecting assembly, and a positioning key is arranged on the surface of the outer clamping sleeve. The outer clamping sleeve is adjusted to rotate relative to the middle connecting assembly. The FC connector can adjust the angle between the positioning key on the outer clamping sleeve and the panda eye of the polarization maintaining optical fiber, the angle error is small, it is ensured that the extinction ratio meets the requirement, the performance of the FC connector is ensured, the structure is simple, the problems that the efficiency is low when the FC connector is assembled by the polarization maintaining optical fiber, and the optical fiber cannot be completely protected by the protection sleeve are solved, and the service life is prolonged.

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, ...
