Aluminum stranded fiber optic cable

Aluminum stranded fiber optic cables are durable, flexible, and water-resistant cables designed for high-speed network backbones and harsh outdoor environments.Construction and Design

Aluminum stranded fiber optic cables typically feature multiple loose tubes filled with water-blocking jelly, which house up to 144 fiber strands, providing protection against moisture and environmental stress . The cables include metallic or non-metallic FRP strength members for tensile strength, and an aluminum tape with a PE outer sheath for mechanical, ultraviolet, and environmental protection . Some designs also incorporate steel tape armor for enhanced crush resistance and rodent protection . The stranded structure ensures flexibility and ease of handling during installation.

Key Features

• Water and Moisture Resistance: Gel-filled tubes and water-blocking yarns prevent water ingress .
• Mechanical Protection: Aluminum and steel tape armor protect fibers from impact, crushing, and external forces .
• Tensile Strength: Central strength members and armored layers allow for high pulling forces, suitable for aerial and duct installations .
• Environmental Durability: PE outer sheath and aluminum layers provide UV resistance and protection against harsh outdoor conditions .
• Flexibility and Versatility: Suitable for direct burial, long-distance communication, trunk lines, LAN, and distribution networks .

Applications

Aluminum stranded fiber optic cables are widely used in:

• Telecom and Backbone Networks: For high-speed, long-distance data transmission .
• Direct Burial Installations: Underground deployment requiring high mechanical strength .
• Duct and Aerial Installations: Overhead or conduit installations with high tensile demands .
• Industrial and Harsh Environments: Power grids, remote network expansions, and areas prone to mechanical stress or rodent activity .

Variants

These cables come in various fiber counts (e.g., 12, 24, 48, 144 fibers) and armoring options (aluminum tape, steel tape, or combined) to meet specific network requirements . Customization is available for fiber per tube, sheath materials, and delivery lengths, making them suitable for both short and long-distance communication systems . Aluminum stranded fiber optic cables combine robust mechanical protection, water resistance, and flexibility, making them ideal for backbone networks and challenging outdoor installations.
