The cable consists of a single tube containing 2 to 24 fibers, either filled with water-blocking gel or using a gel-free, dry water-blocking design. When the cable contains more than 12 fibers, they are divided in two groups. A colored thread identifies each group. Physical protection and tensile strength are provided by aramid or fiberglass yarns stranded around the tube.
A wide range of jacket and armoring options is available: UV-stabilized PVC, FR-LSZH (HFFR) materials, PE, corrugated anti-rodent steel, sealed aluminum moisture barrier tape, dielectric armor etc.. A ripcord is located under the jacket to facilitate its removal.
A Fig-8 self-supporting cable is available in all fiber-counts for aerial applications.
