Self-supporting drop optical cable includes central optical fiber(s) with 2 parallel steel wires as the strength members placed on both sides,and an additional strength member(steel wire). Finally a LSZH jacket is extruded outside.
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member （FRP) to form the cable core. Then the cable core is filled with the cable jelly to protect it from water penetration. Finally a PE jacket is extruded.
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the metallic strength member to form the cable core filled with water blocking compound. Then the steel tape (CST) is longitudinally armored over the cable core and a PE inner jacket is extruded. Finally the cable is completed with a blue flame-retardant PVC jacket.
Equipped with the most advanced fiber drawing towers, high-speed proof testers,and other optical and mechanical testing facilities, CROFC is capable of producing 15 million core kilometres fibers and cables with superior performance.
