Abstract
Abstract A light waveguide cable includes a compartment holding at least two side-by-side stacks of light waveguide ribbons. The cable is so dimensioned that the order of the ribbons within any stack, and the relative positions of the stacks with respect to each other within any compartment, do not change under normal cable handling conditions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
A cable comprising a compartment loosely holding at least two stacks of light waveguide ribbons, said stacks abutting each other in a side-by-side relation, wherein the relative order of the light waveguide ribbons within any stack does not change under normal cable handling conditions and the compartment and stacks of light waveguide ribbons are so dimensioned that the relative position of the stacks of light waveguide ribbons in the compartment does not change during normal cable handling conditions.
Claim 2
Dependent Claim
78 words
A cable comprising a compartment loosely holding at least two stacks of light waveguide ribbons, said stacks abutting each other in a side-by-side relation, wherein the relative order of the light waveguide ribbons within any stack does not change under normal cable handling conditions and the compartment and stacks of light waveguide ribbons are so dimensioned that the relative position of the stacks of light waveguide ribbons in the compartment does not change during normal cable handling conditions.
Claim 3
Dependent Claim
60 words
A cable comprising a compartment loosely holding at least two units abutting each other in a side-by-side relation, each unit comprising a thin layer of thermoplastic extruded over a stack of light waveguide ribbons, wherein the compartment and units are so dimensioned that the relative position of the units int he compartment does not change under normal cable handling conditions.
Claim 4
Dependent Claim
60 words
A cable comprising a compartment loosely holding at least two units abutting each other in a side-by-side relation, each unit comprising a thin layer of thermoplastic extruded over a stack of light waveguide ribbons, wherein the compartment and units are so dimensioned that the relative position of the units int he compartment does not change under normal cable handling conditions.
Claim 5
Dependent Claim
81 words
A cable comprising a compartment holding at least two stacks of light waveguide ribbons each bounded by a helically wrapped tape or thread, said stacks abutting each other in a side-by-side relation, wherein the relative order of the light waveguide ribbons within any stack cannot change under normal cable handling conditions and the compartment and ribbons are so dimensioned that the relative position of the stacks of light waveguide ribbons in the compartment does not change during normal cable handling conditions.
Claim 6
Dependent Claim
81 words
A cable comprising a compartment holding at least two stacks of light waveguide ribbons each bounded by a helically wrapped tape or thread, said stacks abutting each other in a side-by-side relation, wherein the relative order of the light waveguide ribbons within any stack cannot change under normal cable handling conditions and the compartment and ribbons are so dimensioned that the relative position of the stacks of light waveguide ribbons in the compartment does not change during normal cable handling conditions.
