Device and method for improving reliability of trunk optical fiber communication network

Abstract

The invention discloses a device and method for improving the reliability of a trunk optical fiber communication network, and the device comprises a fusion splicer body and two sliding blocks, and thetwo sliding blocks are slidably connected to the fusion splicer body. According to the invention, the matched optical fiber cables and the optical fiber patch cords used by the optical signal receiving end are selected according to the distance between the optical signal transmitting end and the optical signal receiving end and the amount of information needing to be transmitted; the influence ofthe transmission channel of the trunk optical fiber on the optical fiber signal and the transmission speed of the optical fiber signal is avoided; meanwhile, optical signal amplification equipment isadditionally arranged on the trunk optical fiber; the condition of serious optical signal loss caused by an overlong trunk optical fiber line is avoided; the anti-vibration layer and the moisture-proof layer are wrapped on the trunk optical fiber cable, so that the influence of environment high-frequency vibration and moisture on optical signal transmission is reduced, the situations of pollution, axial dislocation, end face gaps, break angles, refractive index difference and the like at the welding joint of the two optical fibers are avoided, and the reliability of the main optical fiber communication network is improved.

Description

technical field [0001] The invention relates to the technical field of backbone optical fiber communication networks, in particular to a device and method for improving the reliability of the backbone optical fiber communication network. Background technique [0002] Optical fiber communication refers to the way of transmitting information by using light and optical fiber, which is a kind of wired communication. Light is modulated to carry information. Optical fiber communication systems have revolutionized the telecommunications industry since the early 1980s and have also played a very important role in the digital age. The advantages of optical fiber communication, such as large transmission capacity and good confidentiality, make optical fiber communication the most important wired communication method today. Optical fiber communication network can be divided into digital optical fiber communication system and analog optical fiber communication system according to the ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the main fiber is fused, there is pollution at the core of the main fiber and the connector of the fiber jumper, resulting in impurities in the main fiber, which will affect the transmission speed of the signal in the main fiber;

[0005] 2. When welding the backbone optical fiber, the diameters of the two fiber cores do not match, and there are axial misalignment, end face gaps, bending angles, and refractive index differences at the connection between the backbone optical fiber and the optical fiber jumper;

[0006] 3. The trunk optical fiber line is too long, resulting in serious loss of optical fiber signal in the trunk optical fiber;

[0007] 4. The influence of the transmission channel of the backbone optical fiber on the optical fiber signal;

[0008] 5. Interference caused by high-frequency vibrations to optical fiber signals in the backbone optical fiber communication network;

[0009] 6. In the process of welding two optical fibers, the current optical fiber fusion splicer puts the two optical fibers in the V-shaped groove of the fiber support arm, and then uses the optical fiber clamp to fix the two optical fibers in the fixture on the fusion splicer. During welding, the jig moves horizontally from side to side, bringing the two ends of the two optical fibers into contact, and the electrode rod releases an arc to fuse the two optical fibers together. However, when the jig drives the two optical fibers to move left and right, it cannot drive the two If the opposite end of the optical fiber moves back and forth, there will be an axial misalignment of the two horizontally moving optical fibers, resulting in the spliced ​​optical fiber not meeting the requirements
