Optical fiber processing method

Abstract

The invention discloses an optical fiber processing method, which comprises a gas line detection process, wherein the gas line detection process comprises the following steps: 1) transmitting a laser beam perpendicular to an optical fiber to the optical fiber through a laser transmitter, and receiving the laser beam through a laser receiver; 2) when the intensity of the signal received by the laser receiver changes suddenly, judging that the optical fiber has a gas line, recording the initial position of the gas line, and controlling winding equipment to reduce a winding speed; and 3) when the intensity of the signal received by the laser receiver is recovered, judging that the optical fiber has no gas line, recording the end position of the gas line, and recovering the winding speed of the winding equipment after the gas line section of the optical fiber is completely wound on a winding disc. According to the optical fiber processing method, by setting the additional gas line detection process, the appearance position and the end position of the gas line can be detected online, so that the gas line section can be conveniently processed in the later period, the winding speed of the winding equipment can be controlled to be reduced when the gas line is detected, the tension of the optical fiber is reduced, and the optical fiber is prevented from being broken due to the gas line.

Description

technical field [0001] The invention relates to the field of optical fiber preform rods, in particular to an optical fiber processing method. Background technique [0002] An optical fiber is obtained by heating and drawing an optical fiber preform rod. The existing optical fiber production process generally includes a melting process, a cooling process, a coating solidification process and a winding process. When there are air bubbles in the optical fiber preform, air lines will appear in the optical fiber during drawing. The performance of the optical fiber with air lines cannot meet the requirements and the strength will decrease. When the original drawing speed is maintained, the optical fiber is easy to break. Contents of the invention [0003] Aiming at the above problems, the present invention proposes an optical fiber processing method. [0004] The technical scheme that the present invention takes is as follows: [0005] A processing method for an optical fiber,...
