The cable’s core features a non-metallic central core made of Fiber Reinforced Plastic (FRP), which provides 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.
Any 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.
Furthermore, to add an extra layer of defense against rodent damage, an anti-rodent glass yarn is longitudinally wrapped around the cable. This protective element is then expertly extruded into a cable with a durable polyethylene sheath, offering an additional shield against external factors that could compromise the cable’s integrity.
