Kevlar Yarn Strengthen Aerial Fiber Optic Cable 4 6 8 12 24 Core GYFTY
Description
Thin fibers housed within a flexible tube made of high-strength plastic, filled with a water-resistant compound.
In the core sits a Fiber Reinforced Plastic (FRP), a non-metallic strength component. Tubes and fillers are ar-
ranged around this core to form a tight, circular structure. To prevent water ingress, the cable core is filled with
protective gel. Kevlar yarn surrounds the cable core, serving as a reinforcing strength member. Finally, the cable
is enclosed with a PE sheath for overall protection.
