The GYTA53 fibre optic cable is constructed by placing a 250µm fibre optic cable in a high modulus material pine tube, which is filled with a waterproof compound. At the centre of the core is a metal reinforcement core, which for some cores is also extruded with a layer of polyethylene (PE). The loose sleeving and filler rope are twisted around the central reinforcement to form a compact and rounded core with gaps filled with a water-blocking filler. Plastic coated aluminium tape (APL) is wrapped longitudinally and then extruded with a layer of polyethylene.

Ideal for overhead installation along high-voltage power transmission and distribution networks.
Suitable for railway communication networks and electrified rail infrastructure.
Applications in petrochemical plants, power stations, and high-voltage industrial environments.
Cost-effective solution for extending fiber networks to remote areas using existing infrastructure.
