Optical cable is an important communication cable in today’s society. The information transmission of all sides is inseparable from optical cable. However, the raw material fiber in the structure of optical cable is particularly fragile, which is not only easy to cause loss or even break during construction. There is a certain probability that the operation failure of the personnel will cause the fiber to be unreachable. Therefore, when the optical cable is shipped from the factory, the regular optical cable manufacturer will conduct the disk test on the optical cable, so as to be responsible to the customer. In addition to these two factors, the optical cable is particularly important in the distribution, then the cable distribution What are the aspects that need our attention? Let’s take a look together.
What are the aspects that need attention when the cable is Delivery and installed? It is very important for the construction personnel to understand this knowledge. The difference between fiber optic cable and cable is very large. This includes recyclable properties. Since the fiber is a fragile fiberglass, the internal space requires stricter precision. So if it causes damage, the repair is unrealist.
1. When loading and unloading the optical fiber cable, use lifting equipment such as a forklift or special steps. It is strictly forbidden to roll or drop the fiber optic cable tray directly from the vehicle.
2. It is forbidden to lay or stack the fiber optic cable trays with optical cables. The optical cable trays in the compartments must be protected with wooden blocks.
3. It is not advisable to rewind the fiber cable several times to avoid the integrity of the internal structure of the optic cable. Before the fiber optic cable is laid, it should be inspected and checked for specifications, quantity, test length and attenuation. Each disk is attached to the panel. There is a factory inspection certificate (should be kept in a safe place for future reference), and be careful not to damage the cable when removing the cable guard.
4. During the construction process, it should be noted that the bending radius of the optical cable should not be less than the construction regulations, and the optical cable is not allowed to be excessively bent.
5, the overhead optical cable should be pulled through the pulley, the overhead optical cable to avoid friction with buildings, trees and other facilities, to avoid mopping the floor or rubbing with other sharp hard objects to damage the cable sheath, and if necessary, install protective measures. It is forbidden to forcibly pull the cable out of the pulley to prevent the cable from being crushed and damaged.
6. When designing the optical cable line, try to avoid the easy building search. If it is unavoidable, the optical cable should adopt fire protection measures.
7. In the cable laying construction in which the segment length is compared, if the disk needs to be reversed, the cable must be placed in the “8” plate. Make its cable completely twisted.
8. The selection of the cable connector box must meet the requirements of the YD/T814-1996 standard to ensure that the radius of curvature of the fiber in the connector box is not less than 37.5MM, and the remaining length of the fiber in the connector box is not less than 1.6M. The reinforcing member is firmly fixed on the joint box, and no twisting occurs between the optical cable and the joint box, and the joint box has excellent sealing performance and can prevent moisture from entering.
9. When the optical cable is connected, the joint attenuation should be based on the average OTDR two-way test.
10. After the cable is laid, if it cannot be processed in time, the two ends of the cable should be sealed to prevent water and gas from invading the fiber.
11. When the optical cable is connected, if it is not connected repeatedly, it is recommended to cut off one section and then continue (because the cable end may be damaged by mechanical damage during construction). 12. The optical cable is connected and should be reserved at both ends of the cable connector box. 2. The right amount of fiber optic cable, and a firm disk on the remaining cable rack.
12. After the optical cable is connected, it is advisable to reserve an appropriate amount of optical cable at both ends of the cable connector box, and the solid disk is on the remaining cable frame.
13. The cable tray with optical cable should be rolled and rolled according to the direction indicated by the side panel surface of the disc. The distance should not be too long. Generally, it should not exceed 20 meters. When rolling, care should be taken to prevent obstacles from damaging the packaging board.Optical cable communication can be said to have become the main mode of network transmission nowadays. Every link in network engineering needs to be treated with caution. This will ensure the long-term quality of our projects.
