Armored stranded loose tube outdoor fiber optic cable with metallic central strength member (steel wire), APL moisture barrier, PSP/steel tape armor, and double PE sheath for duct and direct-buried routes.
GYTA53 is an outdoor armored stranded loose tube fiber optic cable with a metallic central strength member (usually steel wire), APL moisture barrier, PSP / steel tape armor, and double PE sheath.
A typical structure includes stranded loose tubes around a metallic central strength member (usually steel wire), tube filling or water-blocking materials, APL moisture barrier, inner PE sheath, PSP / steel tape armor, and outer PE sheath. Fiber count, sheath material, armor structure, and mechanical performance should be confirmed according to final cable design and project requirements.

What is GYTA53 fiber optic cable?
GYTA53 fiber optic cable is an outdoor armored stranded loose tube cable with a metallic central strength member (usually steel wire), an APL (aluminum-polyethylene laminated tape) moisture barrier, corrugated steel tape / PSP armor, and a double PE sheath. It is designed for direct burial, outdoor duct, feeder, and backbone routes where high mechanical protection against crush, rodents, and moisture ingress is required. MapleArashi manufactures GYTA53 cables with 4-144 fibers, G.652D or G.657 fiber types, and customizable sheath, armor, and water-blocking options based on project requirements.
