Four Major Causes of Communication Fiber and Cable Failures

The four major reasons for the failure of communication fiber optic cable lines are as follows. First: The impact of the lightning cable The sheathed components of the cable are all metal conductors. If a short circuit occurs in the power line or a lightning hits a metal part, a strong current will be generated to destroy the cable. Line equipment, even in serious cases, personnel casualties.

Second: Insufficient insulation of optical fiber cable If the 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 cable will break.

Third: Influence of External Force Line failure is caused by the influence of external force in many cases. Since many communication optical fiber cables 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: The fault at the line joint is most likely to fail at the line joint. This is because the optical fiber at the joint has no protection to the original cable structure or the protection force has been significantly weakened, so daily operation protection work can only be performed. Relying on the splice box, this leads to a great increase in the probability of failure.

Street Lighting Pole

We started to manufacture Lighting Pole from 2001 and exported from 2003. We got CE certificate for Lighting pole from 2015.
