Methods and apparatus for forming a cable media
First Claim
1. An apparatus for forming a cabling media using a wire pair including first and second conductor members, each of the first and second conductor members including a respective conductor and a respective insulation cover surrounding the conductor thereof, the apparatus including:
- a) a wire pair twist modulator adapted to impart a purposefully varied pretwist to the wire pair; and
b) a wire pair twisting device downstream of the wire pair twist modulator, wherein the wire pair twisting device is adapted to impart additional twist to the wire pair,wherein the apparatus is adapted to twist the first and second conductor members about one another to form a twisted wire pair having a twist length that purposefully varies along a length of the twisted wire pair, andwherein the twist length purposefully varies by no more than about +/−
0.05 inches from a mean twist length of the twisted wire pair.

Abstract
A method for forming a cabling media includes providing a wire pair including first and second conductor members. Each of the first and second conductor members includes a respective conductor and a respective insulation cover surrounding the conductor thereof. The first and second conductor members are twisted about one another to form a twisted wire pair having a twist length that purposefully varies along a length of the twisted wire pair. The method may include: imparting a purposefully varied pretwist to the wire pair using a wire pair twist modulator; and imparting additional twist to the wire pair using a wire pair twisting device downstream of the wire pair twist modulator.

12. An apparatus for forming a cabling media using a wire pair including first and second conductor members, each of the first and second conductor members including a respective conductor and a respective insulation cover surrounding the conductor thereof, wherein the apparatus is adapted to twist the first and second conductor members about one another to form a twisted wire pair having a twist length that purposefully varies along a length of the twisted wire pair,
wherein the apparatus is further adapted to twist the twisted wire pair and a second twisted wire pair about one another to form a twisted core having a length such that a twist length of the twisted core purposefully varies along the length of the twisted core.
