An unshielded twisted pair (UTP) cable minimizes skew delay of analog signals by enforcing a common electrical length among twisted pairs that carry those analog signals. By applying a different lay length and lay direction to the twisted pair that carries the digital signal, cross-talk from the digital signal onto the analog signals is minimized. A nonconductive filler provides a central core about which the twisted pairs are wound during the bundling process. The presence of the nonconductive core ensures that a minimum distance (i.e., the diameter of the core) is maintained between non-adjacent pairs for the length of the cable.
