Underground Double Armored Direct Buried Fiber Optic Cable For Outdoor Use
Description
This cable design provides protection for single-mode or multi-mode fibers within a sturdy loose tube
made from high modulus plastic, bolstered by a water-resistant compound. In cables with higher fiber
counts, a steel wire, sometimes coated with polyethylene, serves as the central strength member. Th-
ese tubes and fillers are intricately arranged around this core, forming a tight circular cable core. A PSP
(Parallel Steel Tape) is applied lengthwise over this core, filled with a protective compound to resist wa-
ter ingress. Finally, the entire assembly is enveloped in a PE sheath, offering an additional layer of saf-
eguarding.
Application
* Outdoor-Ready Reliability: Tailored for outdoor use, this cable is engineered to endure diverse outdoor
conditions, ensuring dependable performance for outdoor distribution requirements.
* Adaptable Installation Versatility: Its compatibility with aerial installations, pipeline laying, and direct burial
offers versatile deployment options, simplifying installation across various environments.
* Versatility in Communication: Whether for long-distance transmissions or local area networks, this cable
facilitates efficient data transfer across different distances, catering to a broad spectrum of communication
needs and applications.
Characteristic
1 Reliable Mechanical & Temperature Performance: Operates reliably across various temperatures and
mechanical stress levels.
2 Hydrolysis-Resistant High-Strength Tubes: Ensures durability, even in moist conditions.
3 Specialized Fiber Protection: Guards enclosed fibers from potential damage.
4 Balanced Crush Resistance & Flexibility: Offers resilience while staying flexible under pressure.
5 PE Sheath with UV Protection: Shields against UV radiation, maintaining cable integrity.
