With the development of network, optical fiber, as a medium for data transmission in integrated cabling system, has the advantages of high transmission speed and long distance, and is more and more used by people. As we all know, the optical fiber is non-conductive, not affected by the impact current, the optical cable also has good protective performance, the metal parts in the optical cable to the ground insulation value is high, lightning current is difficult to enter the optical cable, but the optical cable has a strengthened core, especially the directly buried optical cable with armor layer, the optical cable will be burned or damaged by lightning.
The main measures of optical fiber lightning protection in integrated cabling project.
1, the lightning protection of the linear optical cable line: ① The local grounding method, the metal parts of the optical cable should be connected at the junction, so that the strengthening core, moisture proof layer and armor layer of the trunk section of the optical cable are connected. ② According to the provisions of YDJ14-91, the moistureproof layer, armored layer and strengthening core at the cable junction should be electrical disconnection treatment, and are not grounded, and are in a state of insulation to the ground, which can avoid the accumulation of optical cable induced lightning current, and can also avoid the impedance difference between the lightning protection drainage line and the optical cable metal component to the ground circuit and lead to the introduction of optical cable from the grounding device.
2, overhead cable: overhead cable should be electrically connected, grounding every 2 kilometers, grounding can be directly grounded, can also be grounded through the appropriate surge protection device. The suspended wire has the protective effect of overhead ground wire.
After the cable enters the terminal box, the terminal box should be grounded. After the lightning current enters the metal layer of the cable, the grounding of the terminal box can quickly release the lightning current and play a protective role. The directly buried optical cable is equipped with armor layer and reinforced core, and the outer sheath is PE(polyethylene) sheath, which can effectively prevent corrosion and rodents.
