Abstract: GYFTY is a type of optical fiber cable widely used in the telecommunications industry. This article provides a detailed explanation of GYFTY from four aspects: its structure, advantages, applications, and installation process.
GYFTY (Gel-Filled Loose Tube Fiber Optic Cable) consists of several layers that provide protection and support to the optical fibers within. The innermost layer is the gel-filled loose tube, which houses the individual fibers. This gel acts as a water-blocking element, preventing moisture from penetrating into the cable and causing damage to the fibers.
The loose tube is surrounded by strength members made of aramid yarns or fiberglass rods. These strength members provide mechanical support to protect the fibers against external forces such as tension or bending.
The next layer is an armored steel tape or corrugated steel tape that provides additional protection against rodent attacks and physical damage. Finally, an outer sheath made of polyethylene (PE) or polyvinyl chloride (PVC) encloses all these layers to complete the cable's structure.
Gyfty cables offer several advantages over other types of optical fiber cables:
a) Water Resistance: The gel-filled loose tube design ensures excellent water resistance properties, making GYFTY suitable for outdoor installations where exposure to moisture is inevitable.
b) High Fiber Count: GYFTY can accommodate a high number of fibers in each cable due to its loose tube design. This makes it ideal for long-distance communication networks that require multiple fiber connections.
c) Rodent Protection: The armored steel tape or corrugated steel tape provides effective protection against rodent attacks, ensuring uninterrupted communication even in areas prone to rodent infestation.
Gyfty cables find extensive use in various applications within telecommunications networks:
a) Long-Haul Networks: Due to their high fiber count capacity and robust construction, Gyfty cables are commonly deployed in long-haul networks spanning across cities or countries where large amounts of data need to be transmitted over long distances efficiently.
