Precautions for installation of outdoor single-mode dual-core butterfly fiber optic cable

Outdoor single-mode twin-core butterfly fiber optic cable is a signal transmission carrier for modern communications. It is mainly produced by the four steps of coloring, plastic sleeve (loose sleeve and tight sleeve), cabling and sheathing. Once it is not properly protected during construction on site, it will cause great losses if damaged. So what problems should be paid attention to during the installation of optical cables?

Outdoor fiber optic cable

1. The optical cable reel with optical cable should be rolled in the direction marked on the side panel of the reel. The rolling 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, checking 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 optical 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 single-mode double-core butterfly optical fiber cable should be pulled by pulleys when laying overhead. The overhead optical cable should avoid friction with buildings, trees and other facilities, and avoid damage to the outer skin of the optical cable due to dragging the floor or friction with other sharp and hard objects. Install protective measures. 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. In the design of optical cable lines, flammable objects should be avoided as much as possible. If it is unavoidable, the optical cable should take fire protection measures.

8. In the construction of laying optical cables with relatively long lengths, if they need to be reversed, the optical cables must be placed in accordance with the "8" dial. Leave the cable fully twisted.

9. The selection of the optical cable splice box must meet the requirements of the YD/T814-2004 standard. Make sure that the curvature radius of the optical fiber in the splice box is not less than 37.5mm, and the remaining length of the optical fiber in the splice box is not less than 1.6m. 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.
