Non-metallic Non-Armored Cable GYFTY

The GYFTY fiber optic cable is a non-metallic, non-armored outdoor cable designed for installations in environments with strong electromagnetic interference and frequent lightning activity. Featuring an all-dielectric structure with FRP strength members, GYFTY cable provides stable optical transmission without the risks associated with metallic components.

It is widely used in power transmission systems, aerial installations, duct networks, and telecom backbone applications where electrical isolation is essential.

What Is GYFTY Fiber Optic Cable?

GYFTY is an all-dielectric stranded loose tube fiber optic cable designed for outdoor communication networks. Unlike armored or metallic cables, it contains no metal components, making it highly resistant to electromagnetic interference (EMI) and lightning-induced currents.

The cable structure typically includes:

• Optical fibers inside loose tubes
• FRP (Fiber Reinforced Plastic) central strength member
• Water-blocking materials and filling compound
• PE outer sheath for outdoor protection

👉 This design makes GYFTY ideal for high-voltage and high-EMI environments.

GYFTY Cable Structure Explained

🔹 FRP Central Strength Member

Provides tensile strength while remaining non-conductive.

🔹 Stranded Loose Tube Design

Loose tubes protect fibers from mechanical stress and environmental changes.

🔹 Water Blocking System

Gel filling and water-blocking yarn prevent moisture penetration.

🔹 PE Outer Jacket

UV-resistant polyethylene sheath ensures long-term outdoor durability.

👉 The structure is optimized for safe operation near power infrastructure.
