GYTA53 cable

GYTA53 fiber optic cable is a reinforced version of GYTA cable, specially designed for outdoor installations in demanding environments. Unlike standard GYTA, which offers a simple outer sheath, The GYTA53 features steel strip armor and a double protective sheath, giving it excellent mechanical resistance, protection against humidity and perfect adaptation to direct buried installation. It is ideal for long distance networks, industrial zones and high-stress environments.

Advantages of GYTA53 fiber optic cable

Reinforced mechanical protection

The double-layer shielding structure (steel belt + aluminum-plastic belt) effectively resists lateral pressure, à l'extrusion et aux dommages causés par les rongeurs.

High tensile and compressive strength

Short-term tensile/compressive strength can reach 3000 N, ce qui peut garantir la stabilité du signal même lorsqu'il est directement enterré.

Excellentes performances d'étanchéité à l'humidité

Waterproof internal glue, le ruban aluminium-plastique et l'armure métallique fonctionnent ensemble pour empêcher l'humidité, suitable for high humidity or underground environments.

Reliable long distance transmission

G.652 single-mode optical fiber, attenuation ≤ 0,36 dB/km, suitable for long distance backbone networks.
