Description
Service drop wire are also called waterproof cable, it adopt one or more single-core fiber optic cable around a central strength member to strand, the longitudinally wrap plastic composite tape and water blocking yarns, outside squeeze PE cable jacket, if multi fibers, there will be colored coating inner sheath like blue, orange, green, brown to distinguish.
Features of Service Drop Wire 4 Core
- Waterproof tape around the package, good at water blocking, suitable for outdoor harsh environments;
- High strength steel to enhance tensile strength, good ground performance;
- Easy to install, simple and reliable, suitable for various connectors;
- More single-core cable design.
