As we all know, the integrated cabling project is a relatively complex project, so it is impossible to guarantee zero errors and zero failures during construction. However, it is relatively easy to minimize the failures and errors in the cabling project. Today, here and everyone analyze the four major reasons for the failure of communications fiber optic cable.
First: The impact of lightning
The sheathed components of the optical cable are all metal conductors. If the power line is short-circuited or lightning strikes the metal parts, a strong current will be generated to destroy the optical cable equipment. In severe cases, even casualties will occur.
Second: Insufficient insulation of optical cable
If the communication optical fiber cable is not insulated properly, the strength of the optical cable will be greatly reduced due to stress corrosion and static fatigue after the joint box is filled with water or under damp conditions. In severe cases, the optical cable may break. .
Third: Influence of External Forces
Line faults are caused by external forces in many cases. Since many communication cable lines are laid in the field, the general burial standards are deep below the ground, so it is not possible to effectively avoid the destruction of the optical cable lines caused by many external factors.
Fourth: fault at the line connector
Faults are most likely to occur at the place where the line connector is located. This is because the optical fiber at the connector has no protection to the original cable structure or the protection force has been significantly weakened. Therefore, the daily operation and protection work can only rely on the joint box. The chance of causing a failure has greatly increased.
