Product Description
Factory Supply GYTA53 Fiber Optic Cable 36–288 Core | Aluminum Armored, Singlemode, Direct Burial & Duct Outdoor Cable
GYTA53 Aluminum Armored Direct Burial Fiber Optic Cable is designed for long-distance, high-capacity communication networks. Built with S-Z stranded loose tubes filled with water-blocking gel, this cable provides superior moisture resistance and excellent tensile strength.
Available in 36 to 288 cores, the GYTA53 cable supports singlemode G.652D or G.657A1 fibers, making it ideal for FTTH backbone, metropolitan networks, data centers, and telecom infrastructure.
Its corrugated aluminum armor offers exceptional crush resistance and rodent protection, ensuring reliable performance even in harsh outdoor environments. Suitable for direct burial, duct laying, and underground installations, this cable delivers low attenuation and stable transmission over long distances.
✅ Key Benefits:
-
High fiber count (36–288 cores) for scalable network capacity
-
Aluminum tape armor + PE outer jacket for maximum durability
-
Water-blocking design prevents moisture ingress
-
Easy installation in direct burial or duct routes
-
Compliant with ITU-T G.652D / G.657A standards
Key Features
-
Superior Mechanical & Thermal Stability
Engineered for consistent performance under extreme weather and temperature variations, ensuring long-term reliability.
-
-
Water-Blocking Loose Tube Design
Loose tubes are made from high-strength, water-resistant polymers and filled with thixotropic gel, protecting fibers from moisture and mechanical stress.
-
-
High Axial Stability
S-Z stranded construction and compression-resistant design minimize longitudinal stress and maintain cable integrity during installation and operation.
-
-
UV & Environmental Protection
Outer sheath is made of UV-resistant black polyethylene (PE) to prevent sunlight damage and shield against water ingress.
-
-
Reinforced Structure for Harsh Environments
-
Central steel strength member for superior tensile strength
-
Water-blocking filling compound in loose tubes
-
Fully filled cable core to block longitudinal water migration
-
Laminated aluminum-polyethylene (APL) armor for moisture barrier and rodent protection
Applications
Perfect for direct burial installation, as well as underground ducts, long-haul backbone networks, metropolitan area networks, data center interconnects, and telecom infrastructure projects. Ideal for projects requiring high fiber counts (36–288 cores) and low attenuation singlemode transmission.
