Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
A fiber optic cable comprising: (a) a plurality of free standing composites composed of an optical fiber circumscribed by a wax, each composite circumscribed by a tube-shaped member; and, (b) a jacket, circumscribing said tube shaped members, delimiting a space in which said tube shaped members are disposed.
Claim 2
Dependent Claim
48 words
A fiber optic cable comprising: (a) a plurality of free standing composites composed of an optical fiber circumscribed by a wax, each composite circumscribed by a tube-shaped member; and, (b) a jacket, circumscribing said tube shaped members, delimiting a space in which said tube shaped members are disposed.
Claim 3
Dependent Claim
30 words
The fiber optic cable of claim 1 further including an organic flooding compound disposed in at least a part of said space not otherwise occupied by said tube shaped members.
Claim 4
Dependent Claim
17 words
The fiber optic cable of claim 1 wherein the wax of each free standing composite is colored.
Claim 5
Dependent Claim
31 words
The optical fiber cable of claim 3 further including an organic filling compound in said tube shaped member in which the wax of the free standing composites is essentially non dispersible.
Claim 6
Dependent Claim
115 words
An all dielectric fiber optic cable comprising a plurality of buffer tubes at least one of which contains one or more optical fibers and a jacket of dielectric material circumscribing said plurality of buffer tubes, wherein each buffer tube containing an optical fiber has a sidewall, said sidewall has first and second zones, said first zone comprising a dielectric material essentially free of elongated strength members delimiting a cavity in which said optical fibers are disposed and said second zone is integral with said first zone, circumscribes said first zone, and is comprised of elongated strength members embedded in a dielectric material and at least some of said optical fibers are circumscribed by a wax.
Claim 7
Dependent Claim
115 words
An all dielectric fiber optic cable comprising a plurality of buffer tubes at least one of which contains one or more optical fibers and a jacket of dielectric material circumscribing said plurality of buffer tubes, wherein each buffer tube containing an optical fiber has a sidewall, said sidewall has first and second zones, said first zone comprising a dielectric material essentially free of elongated strength members delimiting a cavity in which said optical fibers are disposed and said second zone is integral with said first zone, circumscribes said first zone, and is comprised of elongated strength members embedded in a dielectric material and at least some of said optical fibers are circumscribed by a wax.
Claim 8
Dependent Claim
12 words
The fiber optic cable of claim 5 wherein the wax is colored.
Claim 9
Dependent Claim
25 words
The fiber optic cable of claim 6 further including an organic filling compound in said buffer tubes in which said wax is essentially non dispersible.
