Double Jacket Armored Direct Buried Fiber Optic Cable GYTA53 GYTS53
GYTA53 aluminum armored fiber optic cable is designed for underground duct and direct burial applications. 250µm fibers are placed in high-modulus loose tubes filled with water-blocking compound. Tubes are stranded around a central steel wire strength member to form a compact core. An APL moisture barrier and PSP armor provide excellent water and mechanical protection. The cable is finished with PE inner and outer jackets for long-term outdoor durability.
