Abstract
A cable comprises a plurality of conductors arranged in one or more units of a predetermined number of conductors, with each unit having one or more groups of conductors, the conductors of each group having a common color code arranged so that an outer layer of the conductors in a unit presents a predetermined color impression to identify gauge size of the conductors. The invention is particularly applicable to telecommunication cables having a plurality of twisted pairs of conductors, arranged in one or more units each of one or more groups, one conductor of each pair in a group having a common color and the other conductor having a color code indicative of twist type. The cable conductors can readily be separated into readily identified groups, for use in modular splicing for example, and the units are made up so that the outer layer has a color dominance, by the conductors having a common color in a group, to indicate the gauge of the conductors. The units can be identified by a colored binder.
