Telecommunications cable
DC CAFCFirst Claim
1. A telecommunications cable comprising a core having a plurality of pairs of twisted together individually insulated conductors with all of the conductors being of the same gauge and the maximum twist lay of the plurality of pairs being 2.00 inches with a first group of the plurality of conductor pairs having twist lays within a first range, the conductors of the first group having the same insulation thickness which is consistent with providing a nominal characteristic impedance for each conductor pair of the first group within desirable limits and an acceptable signal attenuation, and at least a second group of the plurality of conductor pairs having twist lays within a second range, the conductors of the second group having the same insulation thickness which is different from that for the first group and which is consistent with providing a nominal characteristic impedance for each conductor pair of the second group which is also within the desirable limits and an acceptable signal attenuation.

Abstract
High frequency cable with short twist lays with the insulation thickness of conductors being different from that of others, the thickness of insulation being dependent upon twist lay length so as to achieve a desired characteristic impedance and signal attenuation.
