Loose Tube Fibre Optic Cable
Loose tube fibre optic cable is designed for harsh outdoor environments, where it protects fibre optic cores by housing them in a central, semi rigid tube that is larger than the fibres themselves. The fibers are free to move within the tube, which is filled with a water-blocking gel or has a dry, water-resistant internal layer, preventing stress fractures and moisture damage. These cables are typically constructed with a strength member and a robust outer jacket for added protection against environmental factors and physical stress.
Features
- Construction: Contains one or more tubes, each housing multiple fiber cores loosely packed inside.
- Protection: The “loose” design allows fibers to move freely, which protects them from thermal expansion/contraction and physical stress.
- Water resistance: Uses a water-repellent gel or a dry internal layer to protect the fibers from moisture ingress.
- Strength: Includes a strength member, such as aramid yarn, for structural integrity.
- Durability: Features an outer jacket that is resistant to UV radiation and designed for use in rugged, external environments, with options for rodent protection in certain applications.
Applications
- Long-distance telecommunications and campus networks.
- Outdoor installations in ducts, underground, or aerial.
- Mixed indoor/outdoor applications where protection from the elements is required.
