Optical fiber wringing equipment

Abstract

The invention discloses optical fiber wringing equipment. The equipment comprises a frame, a swing wheel device fixedly arranged on the frame, a front vibration-stopping wheel, and a rear vibration-stopping wheel, wherein the front vibration-stopping wheel and the rear vibration-stopping wheel are rotatingly arranged on the frame, and the rotation axes of the front vibration-stopping wheel and the rear vibration-stopping wheel are in a parallel relationship; the swing wheel device comprises a Z-shaped component, which is driven to rotate by a power device fixedly arranged on the frame; the Z-shaped component comprises two crank handles, wherein the rotation axes of the two crank handles are overlapped, one of the two crank handles is connected to the power device, a swing wheel shaft, whose two ends are respectively connected to the two crank handles, and a swing wheel fixedly arranged in the middle position of the swing wheel shaft; and the axis of the swing wheel shaft intersects with the rotation axis of the crank handles. When using the optical fiber wringing equipment, optical fibers carry out complete vibration between the front vibration-stopping wheel and the swing wheel, and between the swing wheel and the rear vibration-stopping wheel; thus the vibration buffering zone of optical fibers is increased, the wringing force on optical fibers is more even, the non-roundness degree of optical fiber is optimized, the reject rate caused by layering and damage of optical fibers is largely reduced, PMD of optical fibers is reduced, and the actual production speed of optical fibers is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of optical fiber production, and more specifically, relates to an optical fiber twisting device. Background technique [0002] In recent years, the telecommunications market has developed rapidly, and the number of residential users and business users has increased significantly, which has also promoted the construction of optical fiber networks. [0003] Optical fiber communication systems are developing toward large capacity, high speed, and long distances, making optical fiber performance defects such as polarization mode dispersion (Polarization Mode Dispersion, abbreviated as: PMD), which were originally negligible for low-speed systems, become the main reason for limiting transmission distances. factor. The internal factors that cause the PMD instability of the single-mode fiber include the non-circularity of the fiber core and the consistency of the expansion coefficient of the fiber material.

Problems solved by technology

[0005] However, since the optical fiber will be rubbed and squeezed by the two twisting wheels during the twisting process, it is easy to cause damage, delamination and other adverse effects on the optical fiber

[0006] Secondly, when using the above-mentioned equipment to twist the optical fiber, if the drawing speed is increased, the adverse effects such as fiber damage and delamination will be aggravated, so the drawing speed of the optical fiber is limited to a relatively low level, generally 1400 meters per minute

This production speed has been difficult to meet the market demand for optical fiber
