GYTC8S / GYXTC8S Fiber Optic Cable

GYTC8S / GYXTC8S Fiber Optic Cable


The cross-section of GYTC8S/GYXTC8S Cable's is in the shape of "8". The steel strand is suspended, and the double-sided plastic-coated corrugated steel belt forms excellent flattening resistance. With self-supporting overhead steel strand, much installation time and cost is saved. 


As one of the professional optical fibre manufacturing companies, TUOLIMA has been manufacturing fiber optic cable including gytc8s or gyxtc8s cable for over 10 years with ISO, UL, RoHS, REACH certificates. The reliable quality of TUOLIMA products has won its popularity across five continents and the spread is growing. You can check the details of our GYTC8S / GYXTC8S Fiber Optic Cable on this page.  Or you can consult us directly, if you have any questions about TUOLIMA GYTC8S / GYXTC8S Fiber Optic Cable.

Features

The structure of the standard figure-eight self-supporting stranded optical cable is that multimode or single mode fiber optic cables are sheathed in a loose tube made of high modulus plastic, and the tube is filled with a water blocking compound. The center of the cable core is a metal reinforced core. For certain fiber optic cables, a layer of polyethylene needs to be squeezed outside the metal-reinforced core. The loose tube (and filler rope) is twisted around the central reinforced core to form a compact and Round cable core, the gap in the cable core is filled with water blocking filler. The cable core is longitudinally wrapped with steel-plastic composite tape, and placed in parallel with the steel strands while extruding a figure-eight sheath into a cable.

Advantages of GYTC8S / GYXTC8S Fiber Optic Cable

  • Use high-quality optical fiber to ensure that the optical cable has excellent transmission performance

  • Accurately control the excess length of the outdoor fiber optic cable to ensure that the optical cable has excellent mechanical and high/low-temperature characteristics

  • Full-section water-blocking structure to ensure good water-blocking and moisture-proof performance

  • The loose tube is filled with special grease to protect the optical fiber critically

  • The longitudinally clad steel tape strengthens the resistance to lateral pressure of the optical cable
