The optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic outer skin. There is no metal such as gold, silver, copper and aluminum in the câble optique.
La structure de base du câble optique est généralement composée d'une âme de câble, fil d'acier de renforcement, remplissage et gaine, etc.. En outre, il y a une couche imperméable, couche tampon, insulated metal wire and other components as needed.
Le projet de câblage intégré est un projet relativement complexe, so it is impossible to ensure zero faults in the construction of the project. Cependant, it is relatively easy to minimize the faults and mistakes. There are four major reasons for the failure of fiber optic cable lines.
The Impact of Lightning
Les composants blindés du câble optique sont tous des conducteurs métalliques. If the power line is short-circuited or the lightning strikes the metal parts, a strong current will be generated to damage the optical cable line equipment. And even serious casualties will occur.
The Insulation of the Optical Cable Is Not Good
If the optical cable line is not well insulated, the operating strength of the optical cable will be greatly reduced due to stress corrosion and static fatigue. After the splice box enters the water or is wet, et le câble optique se brisera dans les cas graves.
The Influence of External Forces
Line faults are often caused by external forces. Since many optical cable lines are laid in the field, the general burial standard is deep below the stratum. So the damage of many external factors to the optical cable line cannot be effectively avoided
Défaut au niveau du connecteur de ligne
Les défauts sont plus susceptibles de se produire au niveau des joints de ligne. This is because the optical fibers at the joints no longer have the protection power to the original optical cable structure or the protection power has been significantly weakened. Ainsi, les travaux quotidiens d'exploitation et de protection ne peuvent être effectués qu'en s'appuyant sur la boîte à joints.. La probabilité d'échec est considérablement augmentée.
Optical fiber cable is a new generation of transmission medium. Compared with copper medium, optical fiber has greatly improved in terms of security, reliability and network performance. En outre, the bandwidth of optical fiber transmission greatly exceeds that of copper cables. And about the maximum connection distance, it supports is more than two kilometer. And it is an inevitable choice for building larger-scale networks. Because the fiber optic cable has the advantages of good electromagnetic interference resistance, strong confidentiality, fast speed, and larger transmission capacity. Its price is also relatively expensive, and it is rarely used in household occasions.
