Abstract
A fiber optic cable (10) having a core tube (14) with a stack of optical fiber ribbons (12) therein, a jacket (20), and strength sections (30). Jacket (20) includes a non-uniform profile with close profile sections (22) and extended profile sections (26). Strength sections (30) comprise extended profile sections (26), dielectric strength rods (32), and ripcords (34) disposed between the strength rods. When it is desired to prepare fiber optic cable (10) for a cable pulling operation, portions of extended profile sections (26) are removed thereby exposing strength rods (32) and grip surfaces (22a) for receiving a pulling-grip (40). The compact size, flexibility, and light-weight construction of fiber optic cable (10) makes it a craft-friendly cable which is easy to route through cable passageways during the cable pulling operation.
