Single Mode Multimode 2-288 Cores All-Dielectric Non-Metallic GYFTY Fiber Optic Cable for Outdoor Use

The All-Dielectric Outdoor GYFTY Fiber Optic Cable is a non-metallic, non-armored loose tube cable engineered for aerial, direct burial, and duct installations. It is specifically designed for environments with severe electromagnetic interference (EMI), power transmission systems, high-voltage corridors, and lightning-prone areas.

The GYFTY cable supports fiber capacities ranging from 2 fibers up to a maximum of 288 fibers.

• G — Outdoor communication optical cable (Group)
• Y — Loose tube structure
• F — Non-metallic central strength member made of fiberglass-reinforced plastic (FRP)
• T — Loose tube design filled with gel
• Y — Polyethylene inner or outer protective layer

• All-Dielectric Non-Metallic Structure — FRP strength member provides complete electrical isolation.
• High Resistance to Electromagnetic Interference (EMI) — Ensures reliable signal protection in high-voltage environments.
• Excellent Moisture and Water Proofing — Double-barrier defense with gel filling and water-blocking elements.
• High Tensile Strength and Mechanical Stability — Stranded design delivers dependable performance under tension.
• Durable PE Outer Sheath — UV protection for long-term outdoor exposure.
• Lightweight and Flexible Construction — Low mass for easier handling and installation.

Material: Fiber Reinforced Plastic (FRP) rod.

Function: Positioned at the exact geometric center, it acts as the primary load-bearing backbone. It resists axial tension during pulling and prevents the cable from buckling or shrinking under extreme temperature changes. Because it is plastic-fiber based, it provides complete electrical isolation.

Material: Single-mode (typically G.652.D) or multimode glass cores.

Function: The actual data transmission medium. Fibers are placed loosely within the buffer tubes with excess length to ensure they suffer no physical strain when the outer cable stretches under tension.

Material: High-modulus plastic (usually PBT — Polybutylene Terephthalate).

Function: Protects the delicate glass fibers from external lateral crush forces. If the fiber count of the cable is low, solid plastic fillers (dummy tubes) are used to maintain a perfectly round, symmetrical layout around the central FRP.

Material: Waterproof, jelly-like petroleum compound (loose tube filling compound and cable filling compound).

Function: Fills the interior space of the loose tubes. It cushions the fibers, allows them to move smoothly as the cable bends, and acts as the primary defense line against water or moisture vapor penetrating to the glass surfaces.

Material: Water-blocking yarn or tape, held together by a polyester binding thread.

Function: The tubes and fillers are SZ-stranded (twisted alternatingly clockwise and counterclockwise) around the FRP. The entire bundled core is wrapped in water-swellable materials. If water ever breaches the outer jacket, these elements instantly swell to block axial water migration down the length of the cable.

Material: Medium or High-Density Polyethylene (PE).

Function: The outermost defensive armor layer. Black PE provides highly rugged resistance to solar UV radiation, environmental stress cracking, abrasion, and outdoor weathering.
