Home>Products>Special Optical Cable>Figure-8 Steel Tape Armored (STA) Optical Cable
The GYTC8S optical cable structure involves placing 250μm optical fibers into loose tubes made of high-modulus material, with the tubes filled with waterproof compound. The core''''s center is a metallic strength member, which for certain fiber counts is additionally coated with an extruded layer of polyethylene (PE). The loose tubes (and filler rods) are stranded around the central strength member to form a compact circular core, with interstices filled with water-blocking material. A longitudinally applied double-sided plastic-coated steel tape (PSP) is integrated with a steel wire strand into a figure-8 polyethylene sheath.

1. The steel wire strand provides extremely high tensile strength, facilitating self-supporting aerial installation and reducing deployment costs.
2. Excellent mechanical and temperature characteristics.
3. High hydrolysis resistance and superior strength of the loose tube material.
4. Critical fiber protection provided by specialized thixotropic gel filling.
5. The following measures ensure water resistance:
?· Loose tubes filled with specialized waterproof compound
?· Complete cable core filling
?· Double-sided plastic-coated steel tape (PSP) enhances moisture penetration resistance
