Product Description

1. Product Overview

The 24-Core ADSS (All-Dielectric Self-Supporting) Optical Fiber Cable is an all-dielectric, self-supporting aerial fiber optic solution widely used in medium to long-distance telecom and power utility networks. It features a non-metallic design, making it suitable for high-voltage environments, and can be installed without lashing or messenger wires. The cable is typically applied for distances ranging from 100m to 600m, with custom options available for longer spans depending on equipment and environmental conditions.

4. Application Scenarios

• Telecommunications backends deployed over poles.

• Broadband access (FTTH) for institutions and users in remote areas.

• High-voltage power line communication systems.

• Information transmission for oil & gas and railway industries.

• Areas where excavation is impractical, such as mountains and forests.

5. Price-Influencing Factors

5.1 Span Length and Mechanical Design

Cables for longer spans (e.g., 200m, 300m, 500m) require enhanced strength and additional aramid cord, resulting in higher costs.

5.2 Fiber Type and Brand

• G.652D: Standard type with cost-effectiveness.

• G.657A1: Offers better bending performance but higher price.

• Premium-branded fibers may lead to increased costs.

5.3 Sheath Type

• PE sheath: Suitable for voltage below 110kV, more affordable.

• AT (anti-tracking) sheath: Designed for voltage above 110kV, higher cost due to specialized materials.

5.4 Installation Environment

Harsher environments (e.g., ice zones, deserts) require customized cables with heavy-duty jackets or enhanced mechanical protection, increasing the price.

5.5 Standards Compliance

Compliance with international standards (IEC, ISO, etc.) and certifications such as RoHS, as well as adherence to national power grid standards, may add to manufacturing and testing costs.

5.6 Order Quantity and Packaging

• Bulk purchases can achieve a more favorable price per unit length.

• Standard packaging options include 2000m – 4000m per drum, unwrapped reels, or steel drums.

6. Selection Guidelines

1. Confirm the installation span length and the specifications of poles/towers.

2. Select the appropriate sheath type based on the voltage level of the application environment.

3. Verify test reports and compliance certificates of the product.

4. Consider potential natural hazards such as strong winds, ice, and UV exposure.

5. Choose products from manufacturers with relevant certifications (e.g., ISO9001, ISO14001).
