Patent attributes
A communication cable can comprise twisted pairs of electrical conductors for transmitting electrical signals, such as for digital communication or data transmission. The pairs can be twisted to different tightness in connection with managing interference among the pairs. Within the cable, a separator having an economical polymeric composition can maintain the pairs in a desired orientation. The pairs can be insulated with polymeric materials that compensate for relaxed electrical characteristics of the economical polymeric composition of the separator. One or more pairs having relatively tight twist can be insulated with a premium polymeric material that provides a relatively high level of electrical performance. One or more pairs twisted less tightly can be insulated with another polymeric material providing somewhat lesser but still sufficient electrical performance.
