Description
GDTA optical cable integrates optical and electrical transmission for efficient network connectivity. Colored optical fibers are housed in a loose tube made of high-modulus, water-resistant material, filled with moisture-blocking gel for optimal fiber protection. A central metal strength member provides structural support, while insulated copper conductors and the loose tube are helically twisted around it to form a compact, circular cable core. The interstices are filled with water-blocking material for enhanced durability. The cable core is longitudinally wrapped with coated aluminum tape and finished with a polyethylene outer sheath, offering robust performance and reliability for modern access networks.
