Double Steel Wire Armored Fiber Cable

This cable is a reinforced fiber optic cable with APL moisture protection + double steel wire armor structure, designed for environments that require both high mechanical protection and long-term reliability. It can be customized for medium to very high fiber counts, making it ideal for backbone and large-scale communication networks.

Structure & Design

Key Design Features:

• Aluminum moisture barrier (APL) for excellent water resistance
• Double steel wire armor for maximum mechanical protection
• High tensile strength for long-distance installation
• Excellent crush resistance for underground and underwater environments
• Supports medium to very high fiber counts (customizable)
• Suitable for backbone communication systems

Applications

Double Steel Wire Armored Fiber Optic Cable is widely used in:

• River crossing communication projects
• Lake and reservoir fiber optic networks
• Underground backbone communication systems
• Coastal and marine communication infrastructure
• Industrial park backbone networks
• High-risk direct burial environments
• Long-distance telecom trunk lines
• Smart city and metro network infrastructure

Advantages

Extremely High Mechanical Strength

Double steel wire armor provides superior protection against crushing, pulling, and external impact.

Excellent Water Resistance

APL layer effectively blocks moisture penetration and ensures long-term stability.

High Fiber Capacity

Supports large core counts for backbone and metro network applications.

Suitable for Harsh Environments

Ideal for underwater, rocky soil, and high-pressure underground installations.

Long Service Life

Designed for durable and stable operation in demanding environments.

FAQs

1. What is the difference between single SWA and double steel wire armored cable?

Single SWA has one layer of steel wire armor, while this cable has two layers, providing significantly higher mechanical strength and protection.

2. Can this cable be used underwater?

Yes. It is suitable for river, lake, and reservoir crossings where high mechanical protection is required.

3. What is the maximum fiber count?

The cable can be customized from low fiber counts up to high-capacity designs such as 144, 288, or even higher depending on project requirements.

4. What fiber type is used?

Typically G.652.D single-mode fiber is used, with optional customization available.

5. Is this cable suitable for direct burial?

Yes. It is designed for direct burial in harsh soil conditions and high mechanical stress environments.

6. How does APL improve performance?

APL (Aluminum Polyethylene Laminate) acts as a moisture barrier, preventing water ingress and improving long-term reliability.
