Abstract
The present disclosure describes manifold lay lengths for each twisted pair of conductors in a cable comprising at least one twisted pair of insulated conductors, reducing both internal and alien crosstalk. The lay length of each pair can be adjusted, either continuously or in discrete steps, between a shortest lay length and a longest lay length, such that each pair has each lay length at some longitudinal point along the cable. The lay lengths of each pair are staggered in their progression between shortest and longest lay length to avoid pairs having the same lay lengths for any significant length along the cable.
Claims23
A cable, comprising:
- at least two insulated conductors configured in a helical twist having a lay length of a first value at a first longitudinal position along the cable and a second value at a second longitudinal position along the cable.
A pair of insulated conductors, comprising:
- the pair of insulated conductors in a helical twist having a lay length of a first value at a first longitudinal position and a second value at a second longitudinal position.
A method of assembling a pair of insulated conductors, comprising:
- rotating, along an axis, the pair of insulated conductors at a first speed for a first predetermined amount of time resulting in the pair of insulated conductors having a lay length of a first value along a first longitudinal position;
- and
- rotating, along the axis, the pair of insulated conductors at a second speed for a second predetermined amount of time resulting in the lay length having a second value at a second longitudinal position.
A method of assembling a cable, comprising:
- disposing, within the cable, a first two insulated conductors, the first two insulated conductors configured in a helical twist, around a central axis of the cable, having a lay length of a first value at a first longitudinal position along the cable, and a second value at a second longitudinal position along the cable;
- disposing, within the cable, a second two insulated conductors, the second two insulated conductors configured in a helical twist, around the central axis of the cable, having a lay length of a first value at the first longitudinal position along the cable and a second value at the second longitudinal position along the cable;
- and
- the second value of the lay length of the second two insulated conductors the same as the first value of the lay length of the first two insulated conductors.
