The structure of GYTA33 optical cable enhances waterproof and crush resistance functions based on the GYTA cable structure. It involves placing optical fibers in a loose tube made of high-modulus polyester material, filled with waterproof compound. The center of the cable core is a metal strengthening core. For certain fiber count cables, an extruded layer of polyethylene (PE) is added outside the metal strengthening core. The loose tube is twisted around the central strengthening core to form a compact circular cable core, filled with waterproof filler. After being longitudinally wrapped with aluminum tape, an extruded layer of PE inner sheath is applied, followed by longitudinal wrapping with single or double layers of fine round steel wire armor, and finally extrusion of a PE outer sheath to form the cable.
Product features:
Effective protection of optical fibers.
Tight cable structure design.
Excellent mechanical performance and temperature characteristics.
Strong water-blocking and moisture-proof performance.
The circular steel wire armor provides strong tensile and lateral pressure resistance for the cable.
