It is widely used in telecommunication, power, broadcasting and other departments of signal transmission, will gradually become the main body of the future communication network. The following describes the cause of failure in the use of communication cable analysis?

First, the impact of lightning

The armored components of the optical cable are metal conductors, if the power line produces a short circuit or lightning strikes the metal, it will produce a strong current to destroy the optical cable line equipment, and even cause casualties in serious cases.

Second, the insulation of optical cable lines is poor

If the communication cable line is not properly insulated, then after the connector box is flooded or in the case of moisture, the operating strength of the cable will be greatly reduced due to stress corrosion and static fatigue, and in serious cases, the cable will be broken.

Third, the influence of external forces

In many cases, line faults are caused by external forces. Because many communication optical cable lines are laid in the field, the general buried standards are deep below the ground, so it can not effectively avoid the damage of many external factors to the optical cable lines.

Four, the fault of the line junction

It is most likely to fail in the place of the line connector, because the optical fiber at the junction has no protective force for the original cable structure or the protective force has been significantly weakened, so the daily operation protection work can only rely on the connector box, which leads to a great increase in the probability of failure.
