Stranded Loose Tube GYTA Underground Steel Tape Armored Direct Buried Fiber Optic Cable Wire

The structure of GYTA optical cable involves inserting 250µm optical fibers into a loose tube made of high modulus material, which is filled with a waterproof compound. The center of the cable core features a metal reinforced core. For specific core numbers, a layer of polyethylene (PE) is extruded outside the metal core. The tube is twisted around the central strength member into a compact cable core, with gaps filled with water-blocking material. A plastic-coated aluminum strip (APL) is applied longitudinally before the PE sheath extrusion.

Key Performance Features:

• Excellent mechanical and temperature characteristics.
• High strength loose tube material with hydrolysis resistance.
• Special tube filling grease provides critical protection for fibers.
• Compact structure prevents sleeve retraction.
• PE sheath offers superior UV radiation resistance.
• Multiple waterproof measures including single steel wire reinforcement and water-blocking filler.

Complies with YD/T 901 and IEC 60794-1 standards. Storage and use temperature: -40ºC to +70ºC.
