Spiral Steel Tube Armored Fiber Optic Cable 1-12 Core Single Tube With Tight Buffered Fiber
Product Overview
The Spiral Armored Fiber Optic Cable with a single tube structure is an ultra-rugged, highly flexible solution engineered for harsh environments that demand maximum mechanical protection. This specialized optical cable features a micro-diameter stainless steel spiral tube armor, providing unmatched crush resistance while maintaining an incredibly small form factor and exceptional bend flexibility.
Inside the protective steel armor, the cable accommodates from 1 to 12 core tight buffered fibers (900μm). This compact design is the ultimate choice for challenging indoor and outdoor routing where standard cables would easily pinch, crush, or be destroyed by rodents. It is widely used for heavy-duty patch cords, industrial automation links, and field deployments.
Key Performance Advantages
-
Stainless Steel Spiral Armor: A flexible, interlocking steel tube provides 360-degree protection against extreme crushing forces and physical punctures.
-
Rodent & Pest Proof: The tough metallic spiral layer acts as an absolute physical barrier against rats, mice, and other chewing pests.
-
1 to 12 Core Scalability: Highly customizable configuration housing up to 12 color-coded tight buffered fibers within a single compact tube.
-
High Flexibility & Anti-Twist: Unlike rigid corrugated steel armor, the spiral design allows the cable to bend naturally around tight corners without kinking or micro-bending signal loss.
-
Aramid Yarn Strength: Integrated high-tensile aramid yarn provides excellent pull strength during difficult cable pulling installations.
