Gydta type optical cable

GYDTA is an outdoor, metal-reinforced, loose tube optical cable with ribbon fiber organization, designed for high-density communication networks.OverviewThe GYDTA optical cable is a layered, circular, non-self-supporting outdoor cable primarily used in communication networks for backbone or long-distance transmission . It features optical fiber ribbons housed in loose tubes, which are filled with water-blocking compounds to protect the fibers from moisture and environmental hazards . The cable is reinforced with a metal strength member, typically a steel strand, providing tensile strength and structural stability .Structure and MaterialsFiber Organization: The optical fibers are arranged in ribbons, allowing for high-density fiber counts and efficient mass fusion splicing .Loose Tube: High-modulus plastic loose tubes encase the fiber ribbons, filled with thixotropic water-blocking gel to prevent hydrolysis and moisture ingress .Central Reinforcement: A metal core (steel or aluminum) forms the skeleton of the cable, around which loose tubes and filling ropes are helically stranded .Sheathing: The cable is wrapped with aluminum tape and a polyethylene (PE) outer sheath, providing mechanical protection, UV resistance, and durability in outdoor environments .Tensile and Environmental Protection: The design ensures good tensile performance, temperature resistance, and moisture protection, making it suitable for direct burial or duct installation .ApplicationsOutdoor Communication Networks: Ideal for backbone networks, long-distance fiber deployment, and high-density fiber routing .Direct Burial or Ducts: The metal reinforcement and protective sheathing allow installation in underground ducts or direct burial scenarios .High-Density Fiber Management: Ribbon fiber organization supports mass fusion splicing and efficient network expansion .Key FeaturesHigh fiber density with ribbon configurationLoose tube design with water-blocking gelMetal strength member for tensile supportAluminum-polyethylene sheath for environmental protectionSuitable for outdoor, duct, or buried installationsCompatible with standard ribbon fusion splicers and closures In summary, GYDTA cables are robust, high-performance outdoor optical cables designed for reliable communication in demanding environments, combining metal reinforcement, loose tube ribbon fiber organization, and protective sheathing to ensure durability and efficient network deployment.
