1. Features ● Small diameter, light weight, easy construction ● ● fiber excess length control and stability after a cable, fiber additional attenuation near zero dispersion value change ● Excellent environmental performance 2. Application Laying ● Overhead ● wear 3. buried pipe ● ● central loose tube structure of a coated optical fiber protection ● Fiber cable concentrated in the center, to strengthen both sides of pieces distributed in the cable sheath ● has a water-repellent layer between the strip and the cable core ● Two-sided plastic coated corrugated steel - PE outer sheath ● Two wire bonding parallel strengthening of 4. Features ● excellent water-repellent layer, with good water permeability capability ● adhesive strip the outer sheath and metal reinforcement, Tension excellent performance ● Impact beam tube design, optical fiber cable in the resistance to lateral forces suffered minimize Note: according to user requirements and design a row of non-metallic structures such as: GYFXTW 5. Scope ● long-distance communications, office Communication between, more suitable for the southern region
