It is widely used in modern telecom and power communication networks, and its performance can be better understood through the following four aspects: Structure & Design, Applications, Advantages, and FAQs.

1. Structure & Design

GYFTY fiber cable is a fully non-metallic loose tube fiber optic cable designed for outdoor duct installation.

• Central strength member: FRP (Fiber Reinforced Plastic)
• Loose tube: High-modulus plastic material, filled with water-blocking gel
• Water blocking system: Gel or water-blocking yarn to prevent moisture penetration
• Fillers (if needed): To maintain round cable structure
• Outer sheath: UV-resistant PE jacket
• Metal-free design: No steel or aluminum components, fully dielectric structure

This construction ensures excellent mechanical balance while maintaining complete electrical insulation.

2. Applications

GYFTY cable is widely used in environments where electrical safety and EMI protection are important.

• Outdoor duct installations in telecom networks
• Areas near high-voltage power lines
• Suburban and rural backbone networks
• Electrical substations and power utility communication systems
• FTTH feeder and distribution networks in interference-prone zones

It is especially suitable for environments where metallic cables cannot be used.

3. Advantages

• Fully dielectric structure: No metal components, safe for high-voltage areas
• Lightning resistant: Eliminates risk of electrical induction damage
• Anti-electromagnetic interference (EMI): Stable signal transmission
• Lightweight design: Easier installation and handling
• Good mechanical strength: FRP provides strong tensile support
• Corrosion-free: Ideal for humid or chemically aggressive environments
• Flexible installation: Suitable for duct and aerial use (depending on design)

4. FAQs

Q1: What does GYFTY stand for?

GYFTY is a type of non-metallic loose tube fiber optic cable where “F” indicates a fully non-metallic (FRP) strength member.

Q2: Can GYFTY cable be used in high-voltage areas?

Yes. Since it contains no metal, it is highly suitable for installations near power lines and electrical substations.

Q3: Is GYFTY suitable for direct burial?

It is mainly designed for duct and aerial installation. For direct burial, armored versions like GYTA53 are recommended.

Q4: What is the main difference between GYFTY and GYTS?

GYFTY is non-metallic (FRP), while GYTS contains steel tape armor. GYFTY is better for lightning protection and EMI resistance.

Q5: Does GYFTY support long-distance transmission?

Yes. It supports standard single-mode fiber transmission for long-distance telecom backbone networks.
