Characteristics: 1. Precisely design and control fiber excess length in tube and cable lay length to optimum to ensure excellent strain property in tensile strength and temperature property. 2. Tube material with good temperature property and high Young's modulus, tube filled with compound of non-detectable separated hydrogen to ensure the long term stability in transmission for two long wavelength windows. 3. Following measures taken to ensure cable moisture-proof and corrosion-proof properties: I. High Young's modulus phosphide steel wire as central strength member. II. Tubes and all interstices of cable core filled with moisture-proof and water blocking compound ensure no longitudinal water penetration. III. Two side coated aluminum tape closely bonding to PE sheath ensure radial moisture-proof IIII. Wo side coated corrugated steel tape armoring with close bonding at overlap and water swollen tape longitudinal folded inside steel tape ensure not only the crush resistance of cable but also no longitudinal water penetration and radial moisture-proof 4. Rigorous process and raw materials control and ensure stability of fiber optic cable over 30 years.
