Abstract: An electrical cable has twenty or more twisted pairs of conductors therein formed into units of three twisted pairs and four twisted pairs, with a centrally located additional four pair unit. Dielectric film or tape partially surrounds either the three pair units or the four pair units or both to maintain separation of each unit from adjacent units. The conductors of the pairs in each unit have different twist lengths relative to the other conductors in the unit, and the units have different lay lengths, depending on the number of pairs in each unit.
