TUBE CABLE FOR AIR BLOWN INSTALLATION AND TUBE FOR THE SAME

摘要

An air-blown tube and a tube cable for the air-blown tube are provided to increase an amount of the air-blown tube enclosed by the tube cable by decreasing a contact size between an optical fiber unit and an inner wall of the tube. A tube cable for the air-blown tube is used to enclose air-blown tubes therein. The tube cable includes at least one tube(102) and a cable sheath(100). A through-hole(104) is formed, such that an air-blown optical fiber unit is inserted into the tube in a horizontal direction through the through-hole. A cross-section of the tube has a polygonal shape. The cable sheath encloses the tubes.
