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.

Overhead Optical Cable (GYTS)

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.

Butterfly-Type Fiber Optic Cable GJXFH

GJXFH optical cable features a central fiber core, with two parallel non-metallic strength members placed on either side, encased in a low-smoke, halogen-free, flame-retardant sheath produced via extrusion.

Butterfly-Type Fiber Optic Cable GJXH

The GJXH optical cable features an optical fiber positioned at the center, with two parallel steel wires placed on either side as reinforcing elements, encased in a low-smoke, halogen-free, flame-retardant sheath produced via extrusion.

Self-supporting butterfly-type indoor optical cable GJYX(F)CH

The product is compact in size, lightweight, and features a streamlined, space-saving design. It incorporates a unique groove system that allows for easy stripping of optical cables without the need for tools, making installation exceptionally convenient.

Pipeline Butterfly-Type Optical Cable GJXFHA

The mechanical and physical properties of the jacket meet the requirements of relevant standards; the butterfly optical cable, using G.657 bend-insensitive fiber, exhibits excellent resistance to bending.

Standard All-Dielectric Self-Supporting Optical Cable (ADSS)

ADSS optical cables feature a loose-tube stranded structure. The optical fibers are encased within loose tubes made from high-modulus polyester material, and these tubes are filled with a water-resistant compound. The loose tubes (along with filling strands) are tightly twisted around a non-metallic FRP central strength member, forming a compact cable core. Any gaps within the cable core are completely filled with water-blocking gel. Finally, a polyethylene (PE) inner sheath is extruded over the cable core, followed by two layers of aramid yarn spirally wrapped in opposite directions for added strength, and topped off with either a polyethylene (PE) outer jacket or an anti-corrosion (AT) jacket designed to withstand electrical erosion.

Optical Fiber Composite Overhead Ground Wire (OPGW)

OPGW optical cables place optical fibers within the ground wire of overhead high-voltage transmission lines, creating a fiber-optic communication network along the transmission line. This structural design combines the dual functions of a ground wire and communication capability.
