Optical fiber sealing tooling and method for optical fiber sealing

Abstract

The invention discloses an optical fiber sealing tooling and a method for optical fiber sealing. The optical fiber sealing tooling comprises a soldering clamp for soldering the optical fibers and a metal bushing, refrigeration devices arranged on two sides of the soldering clamp, and clamping grooves are formed on the top of the refrigeration device for accommodating the optical fibers. The optical fiber sealing tooling provided by the invention, in the soldering process, melts the solder by transmitting the heat to the metal bushing through the soldering clamp and conducting the heat to the solder. On two sides of the soldering clamp, the refrigeration devices are installed in proximity to the metal bushing to realize cooling of the optical fibers, protect the optical fiber coating layer from burning, improve the reliability of the optical fiber and thus reduce the risk of losing efficacy of the product. The invention also discloses an optical fiber sealing method, comprising steps of heating the metal bushing in order to solder the optical fibers with the metal bushing, and, in the meantime, cooling the portions on the optical fibers positioned outside the metal bushing and in proximity to the end portion of the metal bushing. The method is beneficial for improving the reliability of the optical fiber and reducing the risk of losing efficacy.

Description

technical field [0001] The present invention relates to the technical field of optical fiber sealing, and more specifically, relates to an optical fiber sealing tool, and also relates to an optical fiber sealing method. Background technique [0002] With the rapid development of modern science and technology, optical communication technology has become a major communication method for global communication. In optical communication, the signal transmitted by the laser is transmitted to the detector through the optical fiber, and the detector receives the signal transmitted by the optical fiber. Since both the laser and the detector are very sensitive to humidity, it is necessary to seal the laser and the detector after they are coupled to the optical fiber, so as to avoid the influence of humidity on the laser and the detector. [0003] In the prior art, the most common process for sealing the optical fiber is to seal the optical fiber in a metal tube with low-temperature gl...

Problems solved by technology

[0005] Because the coating layer of the optical fiber beyond and close to the two ends of the metal sleeve 101 loses the protection of the coating layer under the action of high temperature, it is easy to cause fiber breakage during the reliability tensile test, thereby causing the product to fail
