ROLLABLE RIBBON FIBERS WITH WATER-SWELLABLE COATINGS
First Claim
1. A fiber-optic cable, comprising:
- optical fibers arranged as a rollable ribbon;
a water-swellable material applied directly to rollable ribbon;
a tube surrounding the rollable ribbon;
a dielectric strength member positioned external to the tube, the dielectric strength member aligned substantially parallel to the tube;
a jacket surrounding the tube; and
a ripcord located in the jacket and positioned along a substantial length of the jacket.

Abstract
A fiber-optic cable having optical fibers that are arranged as a rollable ribbon. Water-swellable material (e.g., superabsorbent liquid, superabsorbent powder, superabsorbent adhesive, etc.) is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials. The rollable ribbon is surrounded by a tube, with a dielectric strength member positioned external to the tube and substantially parallel to the tube. A jacket, with a ripcord along a substantial length of the jacket, surrounds the tube. Also taught is a process for manufacturing a rollable-ribbon fiber-optic cable, in which a water-swellable material is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials.
