Abstract

A fiber optic cable (10) having a tube assembly (20) therein. Tube assembly (20) includes an optical fiber group (22) in a tube (21). Optical fiber group (22) comprises a medial optical fiber subgroup (23) and lateral optical fiber subgroups (24a,24b;25a,25b;26a,26b) adjacent thereto. Subgroups (24a,24b;25a,25b;26a,26b) define a step-like profile for maximizing optical fiber packing density of tube assembly (20) and/or defining a high fiber count cable (10). In an exemplary embodiment, fiber optic cable (10) can include strength assemblies (30) on opposing sides of tube assembly (20) for defining a preferential bend plane in fiber optic cable (10).
