ASEAN Gydta Optical Cable

GYDTA optical cables are high-capacity, durable outdoor fiber optic cables designed for long-distance communication networks, supporting up to 576 fiber cores.

Structure and Design

GYDTA cables feature a stranded loose tube design where multiple fiber ribbons (4, 6, 8, or 12 fibers per ribbon) are placed inside loose tubes made of high-modulus plastic (PBT) and filled with a waterproof compound to protect the fibers from moisture and mechanical stress . The central core is reinforced with a metal strength member, typically steel, sometimes coated with polyethylene (PE) for additional cushioning . Loose tubes and filler ropes are twisted around the central core to form a compact, circular cable core, with gaps filled by water-blocking compounds. The cable is then wrapped with a plastic-coated aluminum tape and extruded with a PE outer sheath for environmental protection .

Key Features

• High Capacity: Supports 72 to 576 fiber cores, making it suitable for large-scale communication networks .
• Durability: Resistant to harsh weather, extreme temperatures, moisture, and rodent damage, ideal for outdoor applications .
• Flexibility: The stranded loose tube design allows easier installation in ducts, aerial, or trench environments .
• Mechanical Protection: Aluminum tape armor and steel core provide excellent tensile strength and bending performance .
• Temperature Range: Operates effectively between -40°C and +70°C .

Applications

GYDTA cables are widely used in metropolitan area networks, wired access networks, interoffice communication, and outdoor access networks. They are suitable for duct, aerial, and trench installations, providing high-capacity transmission for long distances while maintaining fiber integrity . The ribbon loose tube design is particularly effective for segments requiring large fiber counts.

Advantages

• High fiber density with small diameter and lightweight design .
• Strong water-blocking and moisture-proof performance .
• Excellent UV and abrasion resistance due to PE outer sheath .
• Enhanced compressive strength and rodent resistance for outdoor deployment . In summary, ASEAN GYDTA optical cables are robust, high-capacity fiber optic solutions optimized for outdoor communication networks, offering durability, flexibility, and protection for large-scale data transmission.
