Abstract
A protective covering system for optical cables includes a plurality of links which may be coupled together to form a two-layer barrier to protect optical fiber positioned with the coupled links. Each link includes a first portion and a wider second portion. The first portion of a first link is insertable in the second portion of a second link such that the first portion of the first link and the second portion of the second link overlap one another radially. The ends of each portion include oppositely extending flanges, at least one of which is temporarily deformable when the first link is inserted into the second link. When the first and second links are secured to one another, the coupled links are free to move axially and to tilt relative to each other.

A protective covering system for an optical fiber comprising:
- a plurality of links that are coupleable together, wherein each link includes:
- a first cylindrical portion defined about a central axis, the first cylindrical portion including an receiving end of the link;
- a second cylindrical portion defined about the central axis, the second cylindrical portion including an insertion end of the link, wherein the second cylindrical portion has a lesser diameter than the first cylindrical portion;
- a base extending radially outwardly relative to the central axis from the second cylindrical portion to the first cylindrical portion, the base including an outer wall facing toward the insertion end of the link and an inner wall facing toward the receiving end of the link;
- a rear flange defined at the receiving end of the link and extending inwardly toward the central axis;
- a front flange defined at the insertion end of the link and extending outwardly away from the central axis;
- wherein, when adjacent links, including a forward link and a rearward link, of the plurality of links are coupled together:
- (i) the rear flange of the forward link is positioned axially between the outer wall of the rearward link and the front flange of the rearward link, and
- (ii) the front flange of the rearward link is positioned axially between the inner wall of the forward link and the rear flange of the forward link;
- wherein the front flange of each link includes a first surface facing the base;
- wherein the front flange of each link is tapered such that a second surface of the front flange extends away from the first surface toward the central axis;
- wherein the front flange of each link includes a third surface extending between the first surface and second surface;
- wherein the rear flange of each link includes a fourth surface facing the base;
- wherein the rear flange of each link is tapered such that a fifth surface of the rear flange extends away from the fourth surface and away from the central axis;
- wherein the rear flange of each link includes a sixth surface extending between the fourth surface and fifth surface;
- and
- wherein the sixth surface is nearer to the central axis than is the third surface.
