Structure

The GYFTA53 is an armored fiber optic cable with a loose tube design.
It has a central strength member made of metal materials, providing high tensile strength and crush resistance.
The loose tubes containing the optical fibers are made of materials like polypropylene (PP) or other suitable plastics.
The loose tubes are filled with water-blocking materials to prevent moisture intrusion.
The cable has an armored layer, typically made of corrugated steel tape, for additional protection against external factors.
The outer sheath is made of polyethylene (PE) for environmental protection.
Central strength member (CSM): Fiber glass plastic FRP
Tube: Thermoplastic material, containing up to 12 optical fibres fil ed with a low viscosity, thixotropic, non-melting gel ful y compatible with fibre coating and tube material
Stranding: The required numbers of elements (tubes and fil ers) are SZ stranded around the central strength member
Reinforcing Armored : Corrugated steel tape and Aluminum steel tape
Sheath: UV stabilised polyethylene in
