In the current rapid development of communication network construction, the choice of optical fiber cables as transmission media is crucial. Especially in the deployment of 5G networks and other high-speed communication networks, operators need to consider various factors such as cost, performance, and installation convenience. ASU and ADSS cables, as two common types of aerial cables, have fundamental differences in many aspects. This report will compare and analyze ASU and ADSS cables to help decision-makers better understand their advantages and application scenarios.

Introduction to ASU Cable

ASU (Aéreos Auto-Suppentados Tubo único) cable is a self-supporting aerial cable, inspired by communication needs in South America, combining the advantages of stranded and central tube cables. The core design of the ASU cable uses two rigid fiber-reinforced plastics (FRP) and a loose tube mixed and twisted to form a stable twist unit. This structure enhances the mechanical and bending performance of the cable, while also reducing the diameter and weight, lowering costs and installation difficulty.

Introduction to ADSS Cable

ADSS (All-Dielectric Self-Supporting) cable is a type of all-dielectric self-supporting cable widely used near or with power lines. Its characteristic is the ability to withstand long spans (up to 1000 meters) without intermediate support, thanks to its strong tensile strength and good dielectric properties. ADSS cables typically use a multi-layer protective structure to adapt to complex external environments.

Comparative Analysis

1. Cost-effectiveness:

• Due to its simple structure and efficient use of materials, ASU cable costs less to manufacture and install compared to ADSS cable. The lightweight design of ASU cable reduces the load on poles, thereby lowering pole rental fees.
• Although ADSS cable performs well in long-span installations, its complex structure and high-performance materials result in relatively higher costs.

2. Performance Comparison:

• ASU cable focuses on practicality and cost-effectiveness, suitable for short-span applications (typically between 50m-250m), especially in urban and rural access network electrification.
• ADSS cable, with its excellent tensile strength and good dielectric properties, is more suitable for long-span installations, especially near power lines.

3. Installation Convenience:

• Due to its lighter weight and flexibility, ASU cable is relatively easy and quick to install, requiring less skill from the installation team and allowing rapid deployment.
• ADSS cable, suitable for long spans and with a more complex structure, requires more expertise and skill for installation, leading to higher installation costs.

4. Adaptability to Application Scenarios:

• Due to its cost-effective nature, ASU cable is more suited for cost-sensitive scenarios with lower span requirements, such as urban and suburban communication network construction.
• ADSS cable, with its unique dielectric properties and long-span capability, is better suited for environments near high-voltage power lines or where large spans are needed.

Conclusion

Both ASU and ADSS cables have their advantages, and the choice between them depends on the specific project requirements and environmental conditions. For cost-sensitive projects that require rapid deployment, ASU cable offers an economical and efficient choice. In environments requiring long spans, especially near electrical infrastructure, ADSS cable becomes the preferable option due to its unique properties. Operators should consider cost, performance, and installation convenience comprehensively to achieve the optimal network deployment strategy.
