The fiber optic splice closure, the new structure, is fixed by multiple stainless steel screws, and is sealed at home and abroad. The fiber optic splice closure is used in harsh environments. Its sealing performance is determined by the quality of the sealing strip, the design of the cable inlet and the fasteners. When selecting, it depends on whether they can meet the airtightness requirements. Can you continue again? Due to the variety of fiber optic splice closures, the use of various connection boxes is different, and only the correct use can ensure the safety and reliability of the cable connection. Let's take a look at the simpler method of fixing the cable. as follows:
1. The steel wire in the cable is the main force point of the cable and the connection box. It must be fastened. If the wire clamp or screw hole is large enough, a few wires should be left as much as possible to enhance the tension and bend the wire head after tightening. Improve the tensile strength.
2. Since the outer layer of the fiber optic splice closure cable is not fixed horizontally, the outer cable must be fixed after fixing the steel wire, otherwise the optical cable will be pulled and the optical fiber inside the disk will be driven to damage or break the optical fiber.
3. The bundle of the inner tube of the optical cable should be used in the tray. It should not be too short or too long. Otherwise, it will slide out of the tray or the beam tube on both sides due to the expansion and contraction of the external force, so that the fiber is broken and the head of the tube is not suitable. In the small bottom hole of the tray, otherwise the beam head will hit the edge of the small hole due to the above reasons, causing the fiber to break.
