Cable design with limited color coding

Claim 2

A telecommunications cable comprising: a plurality of insulated conductors where each conductor has some color identification on its insulation and where said conductors are twisted into conductor pairs, each pair having a first and second conductor with said conductors within each said pair being visibly distinguishable from each other by color; said conductors being assembled into at least one group having a center layer of nonmarker pairs and at least one layer of pairs surrounding said center layer, where each said surrounding layer comprises at least one marker pair having a unique color combination in said group, and other nonmarker conductor pairs having repeating color combinations in said group and being arranged with respect to said marker pair so that each repeating color combination pair can be uniquely identified by its position with respect to said marker pair; and where at least said nonmarker pairs or said center layer pairs and said repeating color combination pairs comprise first conductors having a commonality in visible color characteristics identifying them as first conductors and not second conductors, and second conductors having a commonality in visible color characteristics identifying them as second conductors and not first conductors, to thereby render said cable substantially amendable to routine random splicing of pairs with quick and ready visual identification of first and second conductors.

Claim 3

A multipair multiunit telecommunications cable comprising a cable core comprising: a plurality of units arranged in layers in said core, each unit being identifiable by cable layer and the unit's position in said cable layer; each said unit comprising a plurality of subunits with each subunit being uniquely identifiable in said unit; each said subunit comprising a plurality of insulated conductors, where each said conductor has some color identification on its insulation, and where said conductors are twisted in pairs to form various color combinations, each pair comprising first and second conductors with said conductors within each said pair being visibly distinguishable from each other by color; each said subunit comprising a center layer of pairs and at least one layer of pairs surrounding said center layer, where each said surrounding layer comprises at least one marker pair having a unique color combination in said subunit, and other pairs having repeating color combinations and being arranged with respect to said marker pair so that each repeating color combination pair can be uniquely identified by its position with respect to said marker pair; and where at least said center layer pairs and said repeating color combination pairs comprise first conductors having a commonality in visible color characteristics identifying them as first conductors and not second conductors, and second conductors having a commonality in visible color characteristics identifying them as second conductors and not first conductors, to thereby render said cable substantially amendable to routine random splicing of pairs with quick and ready visual identification of first and second conductors.

Claim 4

A multipair multiunit telecommunications cable comprising a cable core comprising: a plurality of units arranged in layers in said core, each unit being identifiable by cable layer and the unit's position in said cable layer; each said unit comprising a plurality of subunits with each subunit being uniquely identifiable in said unit; each said subunit comprising a plurality of insulated conductors, where each said conductor has some color identification on its insulation, and where said conductors are twisted in pairs to form various color combinations, each pair comprising first and second conductors with said conductors within each said pair being visibly distinguishable from each other by color; each said subunit comprising a center layer of pairs and at least one layer of pairs surrounding said center layer, where each said surrounding layer comprises at least one marker pair having a unique color combination in said subunit, and other pairs having repeating color combinations and being arranged with respect to said marker pair so that each repeating color combination pair can be uniquely identified by its position with respect to said marker pair; and where at least said center layer pairs and said repeating color combination pairs comprise first conductors having a commonality in visible color characteristics identifying them as first conductors and not second conductors, and second conductors having a commonality in visible color characteristics identifying them as second conductors and not first conductors, to thereby render said cable substantially amendable to routine random splicing of pairs with quick and ready visual identification of first and second conductors.

Claim 5

The cable pursuant to claim 1 where each conductor pair having a repeating color combination is arranged adjacent only to pairs having different color combinations.

Claim 6

The cable pursuant to claim 1 where said center layer pairs and conductor pairs having repeating color combinations each comprises a first conductor with a solidly color-stained insulation and a second conductor with natural colored insulation, said second conductors being distinguishable from other second conductors by different stained color identifying marks or lack thereof occurring periodically on said insulation.

Claim 7

The cable pursuant to claim 1 where within each layer said nonmarker pairs have first conductors with identical visible characteristics and where the nonmarker pair first conductors in any layer are visibly distinguishable from the nonmarker pair first conductors in the adjacent layers.

Claim 8

The cable pursuant to claim 5 where said nonmarker pair first; conductors are solidly colored red, blue, or green.

Claim 9

The cable pursuant to claim 5 where said nonmarker pair second conductors are natural insulation, natural insulation with strips of orange stain, or natural insulation with strips of black stain.

Claim 10

The cable pursuant to claim 2 where in each said subunit, a conductor pair having a particular color combination is arranged adjacent only to conductor pairs having different color combinations.

Claim 11

The cable pursuant to claim 8 where in said cable core, each said unit is wrapped with a first binder for identifying the position of said unit in said cable layer and a second binder for identifying said layer in which said unit is located.

Claim 12

The cable pursuant to claim 9 where each said cable layer comprises one marker unit which is wrapped with a first binder having a unique color for said binders in said layer.

Claim 13

The cable pursuant to claim 10 where within each said cable layer, said marker unit is flanked on either side with a unit wrapped with two binders having colors identical to the binders of said other flanking unit.

Claim 14

The cable pursuant to claim 11 where said marker unit in each said cable layer is adjacent to said marker units in adjacent cable layers and where said binders used to wrap each said non-marker unit are of predetermined colors to form a cable core having an identifiable unit arrangement which is symmetrical about said marker units.
