Reasons for communication fiber optic cable failure:

1. The impact of lightning

The armoring components of the optical cable are all metal conductors. If the power line produces a short circuit or lightning strikes the metal parts, a strong current will be generated to damage the optical cable line equipment, and even casualties may occur in severe cases.

Second, the insulation of the optical cable line is poor

If the communication fiber optic cable line is not well insulated, the operating strength of the fiber optic cable will be greatly reduced due to stress corrosion and static fatigue after the connector box is in water or when it is wet. In severe cases, the fiber optic cable may break. .

3. The influence of external forces

In many cases, line faults are caused by external forces. Since many communication optical cable lines are laid in the field, and the general burying standards are deep below the ground, it cannot effectively avoid the damage of many external factors to the optical cable lines.

Fourth, the fault at the line joint

Faults are most likely to occur in the line joints. This is because the optical fibers at the joints no longer have the protective power of the original optical cable structure or the protective power has been significantly weakened, so the daily operation protection work can only rely on the joint box. The probability of causing failures is greatly increased.
