Fig-8 Self-supporting Fiber Optic Cable GYTC8A

General Details

The fiber optic cable consists of a bundle of glass threads (fiber core), each of which is capable of transmitting messages modulated onto light waves. featured with the following advantages compared with traditional copper cable: Fiber optic cables have a much greater bandwidth to carry data than copper cables. Fiber optic cables are less susceptible than copper cables to interference. Fiber optic cables are much thinner and lighter than copper wires.

The 250um bare fiber are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.

Installation method

IEC 60794-1

  • High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost.
  • Good mechanical and temperature performance
  • High strength loose tube that is hydrolysis resistant
  • Special tube filling compound ensure a critical protection of fiber
