Abstract
A fiber optic cable assembly with enhanced flexibility and reduced installation cost in contrast to conventional multiple duct systems. The fiber optic cable assembly comprises a central innerduct adapted to provide a pathway for installing conventional cable by pulling of the cable therethrough. A plurality of air blown fiber (ABF) tubes are positioned around the circumference of the central innerduct for installing air blown optical fiber bundles therethrough, and a plurality of strength elements are provided around the circumference of the central innerduct and interposed among the plurality of air blown fiber (ABF) tubes. A layer of water-blocking material is provided between an outer jacket and the air blown fiber (ABF) tubes and strength members.
