Self-supporting ASS optical cable with 48 cores

48-core self-supporting optical cables, such as GYXTC8Y and GYTC8S, are designed for aerial and outdoor installations with a figure-8 structure, integrating fiber cores and metal or dielectric strength members for high tensile performance.

Overview

A 48-core self-supporting optical cable is typically used for long-haul outdoor communications, aerial deployment between poles or buildings, and can also be installed in ducts or buried environments. These cables combine the fiber core and supporting structure into a figure-8 design, eliminating the need for separate suspension wires and hooks, which improves installation efficiency and reduces costs .

Construction Features

• Core and Tube: Fibers are housed in loose tubes made of high-modulus plastics, often filled with water-blocking compounds to prevent moisture ingress .
• Strength Members:
  • Metallic: Stranded steel wires provide tensile strength and self-supporting capability for aerial installations (GYXTC8Y, GYTC8S), .
  • Dielectric: ADSS cables use fiber-reinforced plastic (FRP) and aramid yarns as non-metallic strength members for environments where electrical insulation is required .
• Jacket Materials: Options include PE, HDPE, steel-LSZH, or double jackets for enhanced environmental protection . Some variants include corrugated steel tape for crush and gunshot resistance .
• Waterproofing: Loose tubes and interstitial spaces are filled with water-blocking compounds, and some designs include PSP moisture barriers .

Mechanical and Environmental Performance

• High tensile strength ensures the cable can span long distances without sagging .
• Hydrolysis-resistant loose tubes protect fibers from environmental degradation .
• Small diameter and light weight make installation easier and reduce load on supporting structures .
• Low dispersion and attenuation maintain signal quality over long distances .

Installation Advantages

• Self-supporting: No need for additional suspension wires; the figure-8 design integrates support and fiber core .
• Versatile deployment: Suitable for aerial, duct, or buried installation .
• Efficient and safe: Reduced installation time and lower labor costs due to integrated support structure .

Common Variants

• GYXTC8Y: Central loose tube, steel wire strength member, PE jacket, suitable for aerial installation .
• GYTC8S: Stranded loose tube, steel wire strength member, corrugated steel tape armored, PE jacket, excellent moisture and crush resistance .
• ADSS 48-core: All-dielectric, FRP central strength member, aramid yarn reinforcement, PE or anti-tracking outer sheath, ideal for electrically sensitive areas . These 48-core self-supporting optical cables provide a reliable, mechanically robust, and environmentally resistant solution for high-capacity outdoor fiber optic networks.
