What problems occurs when the transportation and installation of fiber optic cable

Fiber optic cable products is very fragile thing, need to be more specific protection, therefore, fiber optic cable in the transport, laying and installation process should note the following:

  • With the cable tray cable tray should be marked on the side surface direction scroll, scroll, from not too long, usually not more than 20 meters, rolling should be taken to avoid damage to barrier packaging board.
  • Cable should be used forklifts and other handling lifting equipment or special stage, non-optical disc directly from the car rolling or throwing.
  • Prohibited the cable tray with cable or flat stacked, the cable tray in the car need to be fortified wood.
  • Cable should not be set back several times, so the integrity of the internal structure of fiber optic cable, fiber optic cable laying should be carried out before the appearance of inspections and check specifications, quantity, length and attenuation test inspection and acceptance of a single plate, each plate with cable in nursing board with factory test certificate (should be properly kept for future reference), when the demolition of cable shield to guard against damage to the cable.
  • In the construction process should be noted that fiber optic cable bend radius not less than construction requirements, fiber optic cable does not allow excessive bending.
  • Laying overhead cables, through pulley traction, overhead cable to avoid buildings, trees and other facilities friction, avoid sharp mopping the floor or other hard objects with friction and damage to cable sheath, as necessary, installation of protective measures. After the pulley is strictly prohibited forced out of the traction cable, fiber optic cable has been crushed to prevent damage.
  • In the design of optical cable and then the building should be easy to find as much as possible to avoid, such as can not be avoided, cable fire protection measures should be taken.
  • In the relatively long section of cable laying construction, for back plate, cables must comply with Doon “8” dial up. It completely twisted cable status.
  • Fiber Optic Cable box selection must meet the standards of qualified YD/T814-1996 connector box to ensure fiber in the connector box of the radius of curvature of not less than 37.5MM, fiber remaining in the joint box length is not less than 1.6M, cable reinforcements firmly fixed in the connector box, cable and connector box does not occur between the twist, the joint box sealing performance, can prevent moisture from entering.
  • In the splice, the joint bi-directional OTDR attenuation should be based on the average test subject
  • Fiber optic cable laying completed, if not promptly follow treatment, fiber optic cable ends should be sealed to prevent moisture against the fiber.
  • In the splice, if not continue down several times, and then follow a recommended cut off (due to construction of the cable ends may be subject to mechanical damage).
  • Splice completed, should be set aside in the amount of cable connector box at both ends of the cable, and more than a solid plate in the cable rack.
  • Cable network project in one of the important role, not yet come in handy if there are problems before, resulting in economic losses can not be ignored, so the main points of the content of this article we want to focus, to avoid losses and waste.
