Detailed introduction
The product description
The fibers, 250μm, are positioned in a loose tube made of a high modulus material. The tubes are filled with a waterproof compound. At the center of the cable core is a metal reinforcing core. For some cables with a certain number of cores, a layer of polyethylene (PE) is added to the metal reinforcing core. The loose tube (and filler) is twisted around the central reinforcement core to form a compact and round cable core. The gaps in the cable core are filled with water-blocking filler. The cable is longitudinally coated with PSP and then squeezed with PE sheath.
· Product features · Excellent mechanical properties and temperature characteristics · The loose tube material itself has good water resistance and high strength · The pipe is filled with special oil to provide critical protection for the optical fiber · Specially designed tight structure of the cable Effective prevention of casing retraction · Good compressive resistance and flexibility · PE sheath has good uv radiation resistance · The following measures are adopted to ensure the waterproof performance of the cable: - single wire center to strengthen core - pine casing fill special waterproofing compound - completely fill - cable core Double-sided plastic-coated steel strip (PSP) improves moisture permeability of fiber optic cables. Product Standard GYTS fiber optic cables comply with YD/T 901-2001 and IEC 60794-1 standards
