GYFTA cable is a type of outdoor, non-metallic reinforced, loose tube duct fiber optic cable designed for aerial installations. It features a gel-filled tube to protect fibers from moisture, non-metallic strength members for support, and a PE outer jacket. With no metallic components, it avoids corrosion and electrical conductivity, making it suitable for environments sensitive to EMI and requiring lightweight, yet durable cabling solutions. This innovative cable design combines advanced materials science with optimized engineering to deliver a lightweight, yet robust, alternative for optical fiber transmission.
GYFTA stands for "Non-metallic Strength Member, gel-filled, yarn-layered, fiber optic Cable." Unlike traditional armored cables, GYFTA omits metal components in its reinforcement, substituting them with non-metallic materials. This design choice significantly impacts the cable's weight, flexibility, and resistance to environmental factors such as corrosion and electromagnetic interference.
Non-metallic Strength Members: At the core of GYFTA fiber cables lie non-metallic fibers or synthetic rods that provide tensile strength. These members ensure the cable can withstand pulling forces during installation without deformation, all while maintaining a lightweight profile.
Gel Filling: Each loose tube housing the delicate optical fibers is filled with a gel-like substance. This gel acts as a barrier against moisture ingress, preventing signal degradation and enhancing the longevity of the cable.
Yarn Layering: Surrounding the gel-filled tubes are layers of aramid yarn or similar materials. These layers add additional protection against mechanical stress and abrasion, reinforcing the cable's overall durability.
Outer Jacket: A rugged, UV-resistant jacket encapsulates the entire assembly, safeguarding the cable from environmental hazards like sunlight, temperature fluctuations, and physical damage.
Lightweight & Flexible: The absence of metallic elements makes GYFTA optic cables lighter and more flexible than armored counterparts, facilitating easier handling and installation, especially in confined spaces.
Corrosion Resistance: Non-metallic construction renders these cables impervious to rust and corrosion, extending their lifespan in humid or chemically aggressive environments.
Electromagnetic Interference (EMI) Immunity: By avoiding metal components, GYFTA optical cables do not conduct electricity, making them ideal for installations near power lines or in EMI-sensitive areas.
Cost-Efficiency: Reduced material costs and simplified installation procedures contribute to overall cost savings compared to armored cables.
GYFTA cables find extensive use in various sectors, including:
Telecommunication Networks: Perfect for last-mile connectivity in FTTH (Fiber to the Home) deployments due to their ability to traverse challenging terrains without heavy-duty support structures.
Aerial Installations: Their light weight and self-supporting characteristics make them suitable for aerial deployments where weight-bearing capacity is a concern.
Underground Deployments: In situations where rodent resistance is less critical, GYFTA offers a viable alternative to metal-armored cables for underground installations.
The Non-metallic Strength Member Non-armored Cable GYFTA represents a significant advancement in fiber optic technology, offering a versatile solution that balances performance, durability, and cost-effectiveness.
