Abstract
Bundled cables including a plurality of sub-cables, each sub-cable comprising a plurality of twisted pairs of insulated conductors. In one example, a bundled cable includes first, second and third sub-cables, each comprising a plurality of twisted pairs of insulated conductors that each has a unique twist lay. The first sub-cable has a first lay scheme, the second sub-cable has a second lay scheme that is different than the first lay scheme, and the third sub-cable has a third lay scheme that is different than the first and second lay schemes. The first, second and third sub-cables are twisted together about a longitudinal axis, and a delta in twist lay between a closing lay of any one twisted pair of the first plurality of twisted pairs and a closing lay of any one twisted pair of the second and third pluralities of twisted pairs is at least approximately 0.020 inches.
Claims (18)
