Overhead Optical Cable (GYTS)

Category:
Product Description: The structure of GYTS optical cables involves embedding single-mode or multi-mode optical fibers within loose tubes made from high-modulus polyester material, with the tubes filled with a water-resistant compound. At the cable's center lies a metallic strength member; for certain cable configurations, an additional layer of polyethylene (PE) is extruded over the metal strength member. These loose tubes (along with filling strands) are twisted around the central strength member to form a compact, circular cable core, and the gaps within the core are completely filled with a water-blocking filler. Finally, the cable is completed by longitudinally wrapping it with double-sided chrome-plated plastic-coated steel tape (PSP), followed by extruding a protective polyethylene jacket over the entire assembly.
Product Standard: YD/T 901-2018
Applicable to: Pipelines, overhead structures
Product features:
Precisely controlled fiber slack ensures that the optical cable exhibits excellent tensile performance and temperature characteristics.
The loose-tube material itself boasts excellent hydrolysis resistance and high strength, while the tube is filled with a special gel that provides critical protection for the optical fibers.
Good lateral pressure resistance and softness;
The polyethylene (PE) jacket possesses excellent resistance to ultraviolet radiation;
Employ the following measures to ensure the waterproof performance of the optical cable:
- Single-strand steel wire central reinforcement;
- The loose tube is filled with a special waterproof compound;
- Fully cable core-filled;
