Abstract

The invention discloses an optical fiber twisting equipment, and belongs to the technical field of optical fiber manufacturing. The optical fiber twisting equipment includes a rotating disc and a first limit member and a second limit member which are symmetrically arranged over and below the rotating disc. The first limit member is provided with a first through hole for introducing an optical fiber, and the second limit member is provided with a second through hole for leading the optical fiber out. The rotating disc is provided with at least a pair of third through holes which are symmetricalwith each other relative to the center of the rotating disc. The optical fiber passes through one of the third through holes. The first through hole, the second through hole and the third through holes are provided with smooth inner walls. The optical twisting device is provided with a driving assembly. The rotating disc rotates around the center of the rotating disc driven by the driving assembly so as to twist the optical fiber. The optical fiber twisting device provided by the invention can reduce polarization mode dispersion, can avoid damages to the surface of the optical fiber, and is simple in structure and convenient in adjustment and maintenance.

Description

technical field [0001] The invention relates to the technical field of optical fiber manufacturing, in particular to an optical fiber twisting device. Background technique [0002] Polarization Mode Dispersion refers to the polarization dispersion in single-mode fiber, referred to as PMD (Polarization Mode Dispersion), which is the dispersion caused by the tiny asymmetry of the cross-section of the fiber. speed spread. If the polarization mode dispersion is large, it will cause waveform degradation in the signal light transmitted in the optical fiber, making it difficult to separate adjacent pulses and causing problems such as limited transmission capacity. Therefore, it is desirable to suppress the polarization mode dispersion as small as possible . In addition, the main factor of the slight asymmetry of the cross-section of the optical fiber is that the cross-sectional shape of the optical fiber is an elliptical cross-section. In the case of a method of manufacturing a ...
