ADSS (All-Dielectric Self-Supporting) cable and GYFTA (Gel-Filled Tube Armored) fiber cable are both types of fiber optic cables used for data transmission, but they differ in construction and application.
ADSS cable is a type of aerial fiber optic cable that is designed for installation in overhead power line environments. It features a central strength member made of aramid yarns or fiberglass reinforced plastic (FRP) and a dielectric outer sheath made of materials such as polyethylene or polypropylene. The cable is designed to be self-supporting, meaning that it does not require any additional support structures like a messenger wire. ADSS cables are typically used for long-distance communication in areas with high wind and ice loads, such as high-voltage power lines.
GYFTA cable, on the other hand, is a type of underground or buried fiber optic cable that is designed for direct burial or installation in ducts. It consists of multiple fibers housed in gel-filled tubes, which are surrounded by a central strength member made of steel wire or FRP. The cable is then armored with a layer of steel tape or aluminum tape for protection. GYFTA cables are typically used for local communication networks in urban areas, such as in buildings or campuses.
In summary, while both ADSS and GYFTA cables are used for fiber optic data transmission, ADSS cables are designed for aerial installations in high-voltage environments, while GYFTA cables are designed for underground or buried installations in urban areas.
