Armored Fiber Optic Cable

Armored fiber optic cable’s composition consists of several key components. A 250μm optical fiber is securely housed within a high modulus loose tube, further reinforced with a waterproof compound for environmental protection.

At the cable’s core is a non-metallic FRP (Fiber Reinforced Plastic) central core, providing structural stability.

To create a compact, rounded cable core, the loose tube and filler rope are carefully twisted around the central reinforcing core, ensuring the cable’s shape and integrity.

Gaps within the cable core are diligently filled with a water-blocking filler, safeguarding the optical fibers from moisture.

Additionally, a longitudinally applied corrugated plastic-coated steel tape (PSP) enhances the cable’s resistance to external forces and environmental conditions. The cable is sealed with a polyethylene sheath, adding further protection and insulation.
