Gyts optical cable and GYFTZY optical cable

GYTS is a metal-armored outdoor fiber optic cable for duct and aerial use, while GYFTY is a non-metallic, water-blocked cable designed for power line and electrically sensitive environments.

GYTS Optical Cable

Structure and Features:

• GYTS cables use loose tube stranding technology, allowing fibers to have secondary excess length for stress-free movement under longitudinal stress .
• The central strength member is typically metallic (steel or FRP), providing excellent tensile strength .
• Corrugated steel tape (CST) armor and a PE outer sheath offer crush resistance, gunshot resistance, and protection against mechanical stress .
• Tubes are filled with a water-resistant compound to prevent moisture ingress .
• Fiber counts can go up to 144 cores, making it suitable for high-capacity backbone networks . Applications:
• Ideal for duct and aerial installations.
• Suitable for long-haul communication, LANs, and environments requiring high lateral pressure resistance .

GYFTY Optical Cable

Structure and Features:

• GYFTY is a non-metallic (metal-free) optical cable, often partially metal-free, designed to prevent electrical interference .
• Uses loose tube construction with water-blocking materials to protect fibers.
• The cable is lightweight and flexible, suitable for environments where metal armoring is not desired.
• Fiber counts are generally lower than GYTS, and the cable is designed for simpler installation environments . Applications:
• Primarily used along 10kV and 35kV power lines, where electrical insulation and thunder protection are critical .
• Suitable for non-metallic duct or aerial installations where electromagnetic interference must be minimized.

Key Differences

Both cables are designed for outdoor use, with PE sheaths for UV and chemical resistance, and loose tube designs to protect fibers from mechanical stress and environmental factors . Choosing between GYTS and GYFTY depends on whether metallic reinforcement is acceptable and whether the installation environment involves high-voltage power lines or potential electrical interference.
