The GYFTS04-48F B1.3 is a 48-core, single-mode outdoor fiber optic cable engineered for reliable performance in aerial, duct, and direct-burial installations. It features a stranded loose tube design with PBT tubes filled with water-resistant gel to protect optical fibers from moisture ingress. A non-metallic FRP (Fiber Reinforced Plastic) central strength member provides high tensile strength while eliminating the risk of lightning-induced damage.
The cable core is wrapped with corrugated steel tape (PSP) for enhanced mechanical protection and moisture resistance, and completed with a durable PA12 nylon outer sheath that offers termite-proof, rodent-proof, and bird-proof protection. This cable complies with IEC 60794-1-2 and ITU-T G.652D standards, ensuring world-class quality for long-distance and local area network communication
