Rodent Resistant Fiber Optic Cable

The cable’s core features a non-metallic central core made of Fiber Reinforced Plastic (FRP), providing structural stability. To maintain a compact and circular cable core, the loose tube and filler rope are precisely helically wound around this central reinforcing core, ensuring the cable’s shape and integrity.

Gaps within the cable core are meticulously filled with a water-blocking filler, effectively shielding the optical fibers from moisture.

Furthermore, a longitudinally applied corrugated plastic-coated steel tape (PSP) enhances the cable’s resilience against external forces and environmental conditions. The cable is then enclosed with a polyethylene sheath, adding an extra layer of protection and insulation.

To bolster defense against rodent damage, an anti-rodent glass yarn is longitudinally wrapped around the cable. This protective element is expertly extruded into a cable with a durable polyethylene sheath, providing an additional shield against external factors that could compromise the cable’s integrity.
