In optical fiber cable product is fragile, need more special protection, therefore, optical fiber cable in the transportation, installation and the installation process should pay attention to the following:
1. Equipped with optical fiber cable tray should be according to the direction of plate side panel is marked by the rolling, rolling, distance shoulds not be too long, and should not be commonly more than 20 meters, prevent damage of barrier packaging should be paid attention to when rolling plate.
2. Loading and unloading of cable should be used when the forklift truck and other lifting equipment or special steps, it is strictly prohibited to cable tray direct rolling down from the car, or left.
3. It is strictly prohibited to cable tray with cable flat or stacked, cable plate must fortify wood around a car.
4. The cable is unfavorable plate for many times, in order to avoid the internal structure of the fiber optic cable integrity, cable should be done before laying appearance inspection, check the specifications, quantity, and attenuation single plate test and acceptance test length, every dish cable on guard attached product delivery inspection certificate (should be properly kept, so that the query in the future), remove the cable guard watch the damaged cable.
5. Bending radius of cable should be paid attention to in construction process should not be less than the construction rules, flexion cable is not allowed.
6. Cloth overhead cables should be through the pulley traction, aerial cable to avoid friction and buildings, trees and other facilities, avoid to mop the floor or friction and damage cable sheath, and other sharp hard objects should install protective measures when necessary. After it is forbidden to cable out of pulley traction, forced to prevent damage of fiber optic cable get squashed.
7. The optical cable circuit design should try to avoid Yi Ran buildings, such as inevitable, cable fire protection measures should be taken.
8. During the construction of long comparison of fiber cloth, if you need plate, fiber optic cable must follow such "8" carriage. The cable in torsion condition completely.
9. The selection of cable connector box must meet the requirements of the standard YD/T814-1996 qualified connector box, ensure that the optical fiber connector box inside the curvature radius of not less than 37.5 MM, length of optical fiber remaining within the connector box is not less than 1.6 M, fiber reinforcement of firmly fixed on the connector box, optical cable and connector box won't analyzed.moreover, connector box sealed performance is good, can prevent moisture from entering.
When the optical coupling attenuation, the bi-directional OTDR test average shall prevail
11. Cable laying is completed, if cannot be handled in a timely manner in, should be sealed on both ends of the cable, in order to prevent moisture violations of the optical fiber.
12. When optical fiber, if succeeded not down for many times, suggest cut again after a period of succeeded (due to the construction of cable end possible mechanical damage).
13. Optical completed, should be reserved the right amount of optical cable, optical cable joint box at both ends and solid plate in the cable on the shelf.
Cable is one of the important role of network engineering, if the problems haven't come in handy before, should not ignore the economic losses caused by, so, in this paper, in the hope that we can focus on key points, the content of the waste to avoid loss.
