A Figure 8 fiber optic cable is a type of fiber optic cable that has a distinctive "8" shape in its cross-section.

A Figure 8 fiber optic cable is a type of fiber optic cable that has a distinctive "8" shape in its cross-section. This design integrates the optical fiber(s) within one part of the "8" and a strength member (often made of steel or aramid yarn) in the other part. The strength member provides additional tensile strength, making the cable more durable and easier to install, especially in aerial applications.

Key Features:

1. Dual Structure: The upper part of the "8" typically contains the optical fibers, while the lower part houses the strength member.

2. Aerial Installation: Figure 8 cables are often used for aerial installations because the integrated strength member allows them to be easily strung between poles without the need for a separate messenger wire.

3. Durability: The design provides excellent resistance to environmental factors such as wind, ice, and UV radiation.

4. Ease of Installation: The integrated strength member simplifies the installation process, reducing the need for additional support structures.

Applications:

- Telecommunications: Commonly used in long-distance communication networks.

- CATV (Cable Television): Used for distributing cable television signals.

- Broadband Networks: Suitable for high-speed internet services.

Advantages:

- Cost-Effective: Reduces the need for additional support structures, lowering installation costs.

- High Tensile Strength: Suitable for long-span aerial installations.

- Environmental Resistance: Designed to withstand harsh environmental conditions.

Types:

- ADSS (All-Dielectric Self-Supporting): Contains no metallic elements, making it immune to electrical interference.

- Figure 8 with Metallic Strength Member: Includes a metallic strength member for added tensile strength.

In summary, Figure 8 fiber optic cables are a versatile and robust solution for various telecommunications and broadband applications, particularly in scenarios requiring aerial installation.
