GYTA53 Armored Stranded Loose Tube Cable

Structure
The GYTA53 armored stranded loose tube cable provides exceptionally reliable performance, and this starts with a proven loose tube design. 250μm fiber units are arrayed within each gel-filled, high-modulus buffer tube, and many buffer tubes and filler rods are stranded around a central steel wire to form a compact and circular cable core. The cable core is protected with water blocking material, and aluminum polyethylene laminate (APL) is then used to wrap the cable core longitudinally. Finally, PE inner sheath, PSP (plastic-steel-plastic) layer and PE outer sheath are applied one by one.

For some armored fiber optic cables with specific fiber count, a PE layer shall be applied outside the metallic central strength member.

Characteristic
1. Our armored stranded loose tube cable has high tensile strength and unsurpassed resistance to temperature variation because of its precisely controlled excess fiber length.

2. As mentioned above, the gel-filled loose tube offers critical protections for optic fibers, and the tube itself is constructed by a kind of special material which has good hydrolysis resistance and pretty high strength.

3. The PE sheath enables our outdoor optical fiber cable to have extraordinary flexibility and crush resistance.

4. We take advantage of the following measures to protect both single mode and multimode fiber cables from water ingress.
a. Single steel wire as the central strength member
b. Special water blocking material inside and between loose tubes
c. APL and PSP layers
