In the current general optical fiber cabling network, because the technology and quality of the optical fibers used in the wiring are generally stable, the characteristics of the optical fibers composed of optical fibers and various optical fiber connectors, jumpers, pigtails and other components are relatively stable. And in the actual use of wiring, they are relatively fixed, so most of the reasons that may actually affect the stability of the optical fiber network are concentrated in the connection technology of the optical fiber.

Fiber optic cables have now become an indispensable part of network cabling design. They have the advantages of large communication capacity, strong anti-interference performance, and strong security performance. They are widely used in cabling networks. Facing market demand, fiber optic systems have also entered the level. and desktop applications.

In the current general optical fiber cabling network, because the technology and quality of the optical fibers used in the wiring are generally stable, the characteristics of the optical fibers composed of optical fibers and various optical fiber connectors, jumpers, pigtails and other components are relatively stable. And in the actual use of wiring, they are relatively fixed, so most of the reasons that may actually affect the stability of the optical fiber network are concentrated in the connection technology of the optical fiber. Below, we analyze and discuss the most commonly used fiber optic connection technologies:

1. The way of cold splicing or field grinding fiber optic connector

Anyone who has been engaged in factory manufacturing and production of optical fiber products should be very aware of this. On-site grinding and factory manufacturing are two completely different methods that are incomparable. The factory uses a special grinding machine. Craftsmanship, on-site is manual grinding that cannot adjust the pressure and cannot maintain consistency.

Maybe in the traditional low-speed network in the past, even if the insertion loss and return loss exceed the standard, the connection is unstable, etc., it may be acceptable for network applications, because the optical fiber has enough surplus to absorb the impact of these factors. However, in today's increasingly high-performance network, many indicators and parameters are extremely sensitive, because the link fails to meet the design requirements or is time-consuming and labor-intensive, which makes designers or constructors troubled, and the loss exceeds the network design. Requirements, test failures, etc. occur from time to time.

2. Welding method

Optical fiber fusion splicing is a connection method that is widely used at present. Relatively speaking, fusion splicing is a method with high success rate and connection quality. One of the main factors, because in the process of use and maintenance, the maintenance operation of the equipment is necessary, so its safety is a problem that we must consider. Under normal circumstances, the fusion splicing can obtain a small connection loss, generally below 0.2dB, but the return loss is not easy to control. At the same time, in the process of optical fiber fusion, there are many external factors that affect the quality of fusion. If the current domestic There are not many multi-core ribbon fiber connectors such as MTP, and the ribbon fiber fusion splicer cannot avoid the reality of excessive loss of individual fibers during the fusion splicing process.
