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).
Claims23
A fiber optic cable having a tube assembly, said tube assembly comprising:
- a tube;
- and
- an optical fiber group disposed within said tube, said optical fiber group comprising at least one medial optical fiber subgroup, said medial optical fiber subgroup being flanked by at least two optical fiber subgroups on opposing sides thereof defining first lateral optical fiber subgroups, said first lateral optical fiber subgroups being flanked by respective second lateral optical fiber subgroups;
- said first lateral optical fiber subgroups comprising respective optical fiber counts that are less than an optical fiber count of said medial optical fiber subgroup;
- said group constructed such that sliding contact exists between at least two of said optical fiber subgroups for permitting adjustment of said optical fiber group during cable bending.
A fiber optic cable comprising:
- a set of optical fibers having a gradually decreasing optical fiber count profile comprising at least four optical fiber subgroups surrounded by a tube, said profile being generally symmetrical about a medial optical fiber subgroup of said profile, at least two of said optical fiber subgroups being constructed such that sliding contact exists between at least two of said optical fiber subgroups for permitting adjustment of said optical fiber group during cable bending.
A fiber optic cable comprising:
- a group of optical fibers having a gradually decreasing optical fiber count profile comprising at least two optical fiber subgroups, at least a first one of said subgroups comprising at least one optical fiber ribbon with a ribbon separation feature therein, an edge of a second optical fiber subgroup being aligned with said ribbon separation feature in said first subgroup.
