These cables are constructed with multiple tubes filled with waterblocking jelly with a fibre count up to 144 fibre strands. They form the backbone of high speed networks and give flexibility and versatility to Non metallic FRP strength members in the cable give it good tensile strength, water blocking jelly in the tube and tape over the tube gives it excellent water and moisture resistance. A corrugated steel armouring and two PE sheath gives this cable excellent tensile strength, mechanical, rodent, ultraviolet and environmental protection. They come in larger delivery length, so can also be used in long distance communication system, building interconnections, trunk lines, LAN and distribution networks.
