Problems solved by technology

[0003] The optical fiber aging test is aimed at the service life of the sheath during long-term use. Today, the optical fiber test usually requires deuterium treatment, hydrogen aging treatment, and attenuation performance tests before and after treatment. Hydrogen aging is often done by immersing the optical fiber in water. In the process of actual testing, the two ends of the optical fiber are often connected to the circuit, and then the data is detected through sequential processing. However, during the test process, the circuit will be short-circuited due to the breakage of the optical fiber and cause damage to the electronic equipment. Often due to time and space intervals, the attenuation of the effect of the previous step is uncontrollable, which will affect the accuracy of the actual test

Abstract

The invention discloses a method for testing optical fiber aging performance. The device comprises a test box, a box door is arranged at one end of the test box, and a visible window is arranged at the middle position of the box door, and both sides of the inside of the test box are provided with There is a fixing mechanism, and the optical fiber cable to be tested is detachably connected between the two fixing mechanisms, the length of the middle position of the optical fiber cable to be tested is greater than the distance between the two fixing mechanisms, and the test box is equipped with a temperature control mechanism The method includes the following steps: open the box door and place the optical fiber cable to be tested between the fixed plate and the positioning plate at both sides, and make the two ends of the optical fiber cable clamped and fixed by the silica gel pad by fastening the fixed plate and the positioning plate , close the door and start the temperature control mechanism. The present invention keeps the overall stability of the test box by interval spraying and blowing air to reduce the loss error, calculates and infers the anti-aging performance of the cable through the breaking time, and improves the convenience and effectiveness of the actual test.

Description

technical field [0001] The invention relates to the technical field of optical fiber testing, in particular to a method for testing optical fiber aging performance. Background technique [0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic and can be used as a light transmission tool. The commonly used optical fiber cable is to encapsulate tiny optical fibers in a plastic sheath for laying and connection. It is used as For long-distance information transmission, the aging test of the sheath is often required in the process of optical fiber production. [0003] The optical fiber aging test is aimed at the service life of the sheath during long-term use. Today, the optical fiber test usually requires deuterium treatment, hydrogen aging treatment, and attenuation performance tests before and after treatment. Hydrogen aging is often done by immersing the optical fiber in water. In the process of actual testing, the two ends of the o...
