Gyxtw4-core optical cable

The GYXTW 4-core optical cable is a robust, outdoor armored fiber optic cable designed for aerial, duct, and direct burial applications, featuring a central loose tube, steel wire reinforcement, and water-resistant protection.Structure and ComponentsThe GYXTW cable has a central loose tube design containing 4 optical fibers, which can be single-mode (G.652D, G.657A2) or multimode (OM2/OM3/OM4) depending on network requirements . The loose tube is filled with a water-blocking gel to protect fibers from moisture. Two parallel steel wires run along the cable for tensile strength, mechanical support, and resistance to wind load . The outer sheath is made of UV-resistant black polyethylene (PE), providing durability for outdoor environments and direct burial without additional conduit .Mechanical and Environmental PropertiesTensile Strength: Steel wire reinforcement ensures high resistance to stretching and mechanical stress .Temperature Range: Operates reliably from −40 °C to +70 °C .Flexibility and Crush Resistance: Loose tube and filling compound provide cushioning and protection against compression .Moisture Protection: Gel-filled tubes and optional PSP (plastic-coated steel tape) enhance water resistance .ApplicationsThe GYXTW 4-core cable is suitable for:Telecom backbone networksFTTX/FTTH access networksLAN connections and urban communication systemsAerial, duct, or direct burial installations without additional conduit . It supports high-bandwidth data transmission (1G, 10G, 40G, 100G) and is compatible with major networking equipment brands like Cisco, Huawei, and Mikrotik .Installation AdvantagesLightweight and compact for easy handling and deployment .Armored design allows direct burial and pole mounting without extra protection .Customizable fiber types and core counts for specific project needs .SummaryThe GYXTW 4-core fiber optic cable is a versatile, durable, and high-performance solution for outdoor fiber networks. Its combination of steel wire reinforcement, water-blocking gel, and PE sheath ensures mechanical strength, environmental protection, and reliable data transmission in harsh conditions, making it ideal for telecom operators, ISPs, and large-scale network installations .
