The structure of the optical cable is to insert a 250 μm optical fiber into a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The center of the core is a metal phosphating steel reinforcing core. The structure needs to be in the outer layer of the MDPE material. The casing is twisted around the center reinforcing core to form a compact and round core. The gap in the core is filled with water. Fill or cover the water-blocking strip, use a two-layer double-coated plastic strip and add a layer of steel strands to surround and then extrude a layer of HDPE protective sleeve.
Features
1. Specially designed compact cable structure to meet mechanical properties such as cable stretching and flattening;
2. The loose tube material has good hydrolysis resistance and high strength, and fully protects the optical fiber in the cable;
3, using wrinkle double-sided plastic coated steel belt and HDPE sheathed cable, to meet the direct buried in the soil construction;
4, a layer of steel wire strands effectively prevent the bites of ants and mice, ensure that the cable is safe to use in specific occasions, does not damage the cable, is an effective environmental protection against cockroaches, bite protection measures;
5. Full cable core filling measures are taken to ensure the waterproof performance of the cable after it is buried.
