Central Tube W-Sheath Optical Cable (GYXTW)
The GYXTW optical cable features a structure where single-mode or multi-mode optical fibers are encased within loose tubes made from high-modulus polyester material, with the tubes filled with a water-resistant compound. Outside the loose tubes, double-sided chromium-plated and plastic-coated steel tapes are longitudinally wrapped around the assembly. A water-blocking material is added between the steel tapes and the loose tubes to ensure both the cable's compactness and longitudinal water resistance. Finally, two parallel steel wires are placed on either side before the entire assembly is extruded with a polyethylene (PE) jacket, forming the finished cable.
Fiber Optic Cable for Pipelines (GYTA)
The GYTA optical cable features a structure where single-mode or multi-mode optical fibers are encased within loose tubes made from high-modulus polyester material, which are then filled with a water-resistant compound. At the center of the cable core sits a metallic strength member; for cables with certain fiber counts, an additional layer of polyethylene (PE) is extruded over the metal strength member. The 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 a plastic-coated aluminum tape (APL) followed by extruding a polyethylene jacket over the entire assembly.
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 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.
Directly Buried Optical Cable (GYTA53)
The GYTA53 optical cable features a structure where single-mode or multi-mode optical fibers are housed within loose tubes made from high-modulus polyester material, with the tubes filled internally with a water-resistant compound. At the center of the cable core is a metallic strength member; for certain cable configurations, an additional layer of polyethylene (PE) is extruded over the metal strength member. The 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 a plastic-coated aluminum tape, followed by extruding a polyethylene inner sheath. A double-sided chrome-plated plastic-coated steel tape (PSP) is then longitudinally wrapped around the assembly, after which a polyethylene outer jacket is extruded to finalize the cable construction.
"8"-Shaped Self-Supporting Optical Cable (GYTC8S)
The GYTC8S optical cable features single-mode or multi-mode fiber ribbons housed within loose tubes made from high-modulus polyester material, with the tubes filled internally with a water-resistant compound. At the cable’s center lies a metallic strength member, around which the loose tubes (along with filling strands) are twisted to form a compact, circular cable core. Gaps within the core are completely filled with water-blocking materials, and the assembly is then longitudinally wrapped with plastic-coated steel tape (PSP). Finally, the entire structure is integrated into an 8-shaped polyethylene jacket along with steel wire strands, making it ideal for self-supporting aerial installations.
