Four major reasons for the failure of communication fiber optic cable lines

Four major reasons for the failure of communication fiber optic cable lines.

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 may occur.

Second: poor insulation of optical cable lines

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 closure enters the water or is wet, and the optical cable will break in severe cases. .

Third: the influence 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, so the daily operation and protection work can only be carried out by relying on the splice closure. The probability of failure is greatly increased.
