Description

GYFTY cables are all-dielectric, non-metallic fiber optic cables designed for outdoor installations requiring immunity to lightning, electromagnetic interference (EMI), and corrosion. Featuring a loose tube structure, central FRP (Fiber Reinforced Plastic) strength member, and UV-resistant PE sheath, they are ideal for aerial, duct, or direct burial deployments in power grids, telecom networks, and high-risk environments.
