First Claim
Patent Images
1. An optical fiber cable comprised of:
- a single, hollow buffer tube with a first water blocking gel-like compound and at least one optical fiber disposed therein;
at least one layer of yarn adhesively bonded to an outer portion of said buffer tube;
a second water blockable gel-like compound impregnating said at least one layer of yarn;
a tape layer applied over said at least one layer of yarn and said second water blockable gel-like compound;
a sealant compound applied over said tape layer;
a plastic jacket which encapsulates said tape layer and bonds to said sealant compound; and
two longitudinally extending strength members adjacent said tape layer and at least partially embedded in said jacket approximately 180 degrees apart.

Abstract
The optical fiber cable has a plurality of centrally located optical fiber ribbons. Carrying the optical fiber ribbons is a gel-filled plastic buffer tube. An adhesive layer is applied along the outside of the buffer tube and yarns extend in a contra-helical pattern over the adhesive. The yarns are impregnated with a gel for lubricating the contact points between the yarns and a longitudinally applied mylar tape layer. The mylar tape layer is coated with a thin layer of sealant which permits application of final polyethylene outer jacket provided for additional cable protection. Embedded within the outer jacket is a pair of diametrically opposed, longitudinally extending strength members.
