Optical fiber, to put it bluntly, is glass, which is very fragile. It is easy to be damaged in daily use, or other reasons cause the failure of fiber optic cable lines. This is very common. So what are the reasons for the failure of communication fiber optic cable lines?

Communication fiber optic cable line failure reasons:

First: the impact of lightning

The armored components of the optical cable are all metal conductors. If the power line is short-circuited or the lightning strikes the metal parts, a strong current will be generated to destroy the optical cable line equipment, and even serious casualties will occur.

Second: the insulation of the optical cable line is not good

If the communication 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, and the optical cable will break in severe cases. .

Third: the shadow of external forces

Line faults are often caused by external forces. Since many communication 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.

Fourth: fault at the line connector

Faults are most likely to occur at the line joints. 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. Therefore, the daily operation and protection work can only be carried out by relying on the joint box. The probability of failure is greatly increased.

The above is the reason for the failure of the communication fiber optic cable line. I hope it can help everyone to prevent the failure of the communication fiber optic cable line in advance. Once a failure occurs, it can also be dealt with in time according to the cause of the failure.
