73 kilometers of 24-core optical fiber cable

A 73-kilometer 24-core optical fiber cable is a high-capacity, armored, outdoor-rated cable suitable for long-distance data transmission and backbone networks.

Cable Structure and Specifications

A typical 24-core optical fiber cable, such as the GYTY53 type, consists of 24 individual fibers arranged in loose tubes filled with a water-resistant gel. The fibers are usually single-mode, compliant with ITU-T G. 652.

D or G. 657. A1 standards, ensuring low attenuation, high bandwidth, and good bending performance for long-distance transmission.

The cable includes a central strength member, often a steel wire, around which the loose tubes and fillers are stranded into a compact, circular core. This core is protected by water-blocking tape, an inner polyethylene (PE) sheath, a corrugated steel tape armor (PSP), and an outer PE sheath, providing double-layer mechanical and moisture protection. The steel tape armor enhances crush resistance, rodent protection, and strain performance, making it suitable for direct burial, tunnels, or duct installations.

Mechanical and Environmental Features

Load capacity: Typically designed to withstand longitudinal stress and repeated bending without fiber breakage. Impact resistance: Can endure hammer impacts and twisting cycles without damage. Moisture protection: Gel-filled loose tubes and water-blocking tapes prevent water ingress, ensuring long-term reliability.

Temperature and U

V resistance: Outer PE sheath protects against environmental extremes, suitable for outdoor deployment.

Applications

A 24-core optical fiber cable over 73 kilometers is ideal for: Long-haul backbone networks connecting data centers or telecom nodes.

Outdoor LA

Ns and metropolitan area networks requiring high-capacity transmission. Direct-buried or duct installations where mechanical protection is critical. High-demand communication environments, including 5G backhaul and intercity fiber links.

Summary

This 24-core optical fiber cable provides high-capacity, reliable, and durable transmission over long distances. Its armored, gel-filled, and double-sheathed design ensures protection against mechanical stress, moisture, and environmental hazards, making it suitable for 73 km deployments in outdoor or underground networks. It supports single-mode fibers for long-distance, low-loss communication, making it a robust choice for modern telecom and data infrastructure.
