A communications cable includes: a cable jacket; first, second, third and fourth twisted pairs of insulated conductors positioned within the jacket, the first, second, third and fourth twisted pairs having, respectively, first, second, third and fourth twist lengths, wherein a first difference between the first and third twist lengths and a second difference between the second and fourth twist lengths are greater than the difference between the twist lengths of any other combination of twisted pairs, and wherein a third difference between the third twist length and the fourth twist length is greater than the difference between the twist lengths of any other combination of twisted pairs except for the first and second differences; and a separator positioned between the third and fourth pairs. There is no separator present between the first and second pairs, the second and third pairs, and the first and fourth pairs. A cable of this configuration can provide adequate crosstalk performance while utilizing less material and experiencing improved burn performance over cables with more robust separators. |
