Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic outer skins. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value. Huge waste. So what problems should be paid attention to during the transportation and installation of optical cables?
1. The optical cable reel equipped with optical cable should be rolled in the direction marked on the side panel of the reel. The distance should not be too long, generally not more than 20 meters. When rolling, care should be taken to prevent obstacles from damaging the packaging board.
2. Lifting equipment such as forklifts or special steps should be used when loading and unloading optical cables.
3. It is strictly forbidden to lay or stack the optical cable reels with optical cables, and the optical cable reels in the carriage must be fortified with wooden blocks.
4. The optical cable should not be reversed multiple times to avoid the integrity of the internal structure of the optical cable. Before laying the optical cable, a visual inspection, check the specifications, model, quantity, test length and attenuation, etc., should be carried out for single-reel inspection and acceptance. There is a product factory inspection certificate (should be kept in a safe place for future inquiries), and be careful not to damage the optical cable when removing the cable shield.
5. During the construction process, it should be noted that the bending radius of the optical cable shall not be less than the construction regulations, and the optical cable is not allowed to be excessively bent.
6. The overhead optical cable should be pulled by pulleys. The overhead optical cable should avoid friction with buildings, trees and other facilities, avoid dragging the floor or rubbing with other sharp and hard objects and damage the cable sheath. If necessary, protective measures should be installed. It is strictly forbidden to forcibly pull the optical cable after jumping out of the pulley to prevent the optical cable from being crushed and damaged.
7. When designing the optical cable line, try to avoid the easy building. If it is unavoidable, the optical cable should take fire protection measures.
8. In the construction of optical cable laying with comparative section length, if it needs to be reversed, the optical cable must be placed in accordance with the "8" dial. Leave the cable fully twisted.
9.The selection of optical cable splice boxes must meet the requirements of YD/T814-1996 standard and qualified splice boxes to ensure that the curvature radius of the optical fibers in the splice box is not less than 37.5MM, the remaining length of the optical fibers in the splice box is not less than 1.6M, and the length of the optical cable The reinforcing piece is firmly fixed on the splice box, the optical cable and the splice box will not twist, and the splice box has excellent sealing performance, which can prevent the entry of water vapor.
