HOC Launches Rugged 48core Fiber Optic Cable for Harsh Conditions

Imagine maintaining stable communication lines in extreme weather conditions and complex geological environments. HOC's newly released 48-core CST (Corrugated Steel Tape) armored fiber optic cable is specifically designed to meet these challenges. Featuring multi-layer protection, this cable provides robust support for indoor and outdoor communication networks in demanding conditions.

HOC has announced the launch of its latest innovation—the 48-core CST armored fiber optic cable. The cable employs a loose tube stranded structure containing four loose tubes and two filler ropes, reinforced with glass fiber yarn. At its center lies an FRP (Fiber Reinforced Plastic) strengthening component. The outermost layer features corrugated steel tape armor, with customizable sheath materials such as PE or LSZH available based on customer requirements.

This 48-core cable stands out for its exceptional protection capabilities and environmental adaptability:

• High-Strength Armor Protection: The corrugated steel tape armor provides superior mechanical protection against external impacts, crushing, and rodent damage, ensuring fiber integrity in challenging environments.
• Multi-Layer Waterproof Design: Internal water-blocking materials and water-swellable glass fiber yarn prevent moisture intrusion, maintaining stable fiber performance.
• Outstanding Tensile Resistance: The combination of central FRP reinforcement and high-strength loose tubes delivers excellent tensile strength, accommodating long-distance installation and complex terrain stresses.
• Broad Environmental Compatibility: Customizable outer sheaths adapt to various applications—PE for outdoor direct burial, LSZH (Low Smoke Zero Halogen) for fire-resistant indoor environments.
• Flexible Core Options: Beyond the 48-core version, HOC offers configurations from 12 to 288 cores to accommodate diverse communication network scales.

The 48-core CST armored cable incorporates carefully engineered components to ensure optimal performance under harsh conditions:

Fibers reside in loose tubes filled with gel, providing cushioning against external stress. These tubes spiral around the central reinforcement for a compact, stable core.

The high-strength, lightweight FRP component enhances tensile resistance and rigidity, preventing bending or deformation during installation and use.

Water-resistant gel and yarn prevent longitudinal moisture penetration, protecting fibers from humid conditions.

The tightly wrapped corrugated steel layer offers robust mechanical protection while maintaining flexibility through its wave-like design.

The customizable protective outer layer utilizes materials like weather-resistant PE for outdoor burial or fire-safe LSZH for indoor applications.

HOC's 48-core CST armored cable serves diverse sectors with its reliability and performance:

• Outdoor Networks: Supports metropolitan, access, and backbone networks with stable fiber transmission links.
• Indoor Infrastructure: Enables high-capacity fiber channels for data centers and office buildings.
• Extreme Environments: Ensures reliable operation in mines, tunnels, deserts, and marine settings.
• Direct Burial: Eliminates need for additional conduit protection, reducing installation costs and complexity.

The cable supports multiple fiber types including G.652, G.655 single-mode and 50/125μm, 62.5/125μm multimode fibers with these optical characteristics:
