Abstract
Abstract Fiber optic cable containing, (a) a core of S-Z stranded strands composed of first and second alternatingly repeating and essentially equal first and second sections, each of the first sections having a common direction and degree of lay substantially equal to but opposite to that of the second sections and (b) a sheath circumscribing the fibers containing marks on its outermost surface essentially transversely co-extensive with that portion of the optical fiber where the first section joins the second section.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
84 words
A fiber optic cable comprising: (a) a core containing S-Z stranded strands containing optical fibers having first and second alternatively repeating essentially equal first and second sections, each of the first sections having a common direction and degree of lay substantially equal to but opposite to that of the second section; and, (b) a sheath circumscribing the core containing on its outermost surface at least one indicator essentially transversely co-extensive with that portion of the strands wherever the first section joins the second section.
Claim 2
Dependent Claim
84 words
A fiber optic cable comprising: (a) a core containing S-Z stranded strands containing optical fibers having first and second alternatively repeating essentially equal first and second sections, each of the first sections having a common direction and degree of lay substantially equal to but opposite to that of the second section; and, (b) a sheath circumscribing the core containing on its outermost surface at least one indicator essentially transversely co-extensive with that portion of the strands wherever the first section joins the second section.
Claim 3
Dependent Claim
25 words
The fiber optic cable of claim 1 wherein one or more of the strands comprise at least one optical fiber loosely circumscribed by a tube.
Claim 4
Dependent Claim
24 words
The fiber optic cable of claim 1 wherein one or more of the strands comprise an optical fiber snugly circumscribed by a plastic jacket.
Claim 5
Dependent Claim
19 words
The fiber optic cable of claim 1 wherein the indicator is a mark on the surface of the sheath.
Claim 6
Dependent Claim
13 words
The fiber optic cable of claim 4 wherein the indicator circumscribes the sheath.
Claim 7
Dependent Claim
16 words
the fiber optic cable of claim 4 wherein the mark is a word or a symbol.
Claim 8
Dependent Claim
16 words
The fiber optic cable of claim 1 wherein the indicator is an indentation in the sheath.
Claim 9
Dependent Claim
13 words
The fiber optic cable of claim 7 wherein the indicator circumscribes the sheath.
Claim 10
Dependent Claim
15 words
The fiber optic cable of claim 7 wherein the mark is a word or symbol.
Claim 11
Dependent Claim
22 words
A fiber optic cable of claim 1 wherein the core contains a strength member about which the S-Z stranded strands are disposed.
Claim 12
Dependent Claim
58 words
A fiber optic cable comprising: (a) a core containing S-Z stranded strands containing optical fibers having first and second alternatingly repeating first and second sections; and, (b) a sheath containing the core having at least one indicator on the exterior surface of the sheath to indicate the location of each junction between a first and second strand section.
Claim 13
Dependent Claim
58 words
A fiber optic cable comprising: (a) a core containing S-Z stranded strands containing optical fibers having first and second alternatingly repeating first and second sections; and, (b) a sheath containing the core having at least one indicator on the exterior surface of the sheath to indicate the location of each junction between a first and second strand section.
Claim 14
Dependent Claim
18 words
A fiber optic cable as recited in claim 11 wherein the strands are non-adherently disposed within the sheath.
