High Performance Telecommunications Cable

A telecommunications cable comprising:

• four twisted pairs of conductors;
• and
• a separator spline comprised of a principal dividing strip and a first subsidiary dividing strip attached longitudinally along a first side of said principal dividing strip and a second dividing strip attached longitudinally along a second side of said principal dividing strip, said spline separating said four twisted pairs such that they are arranged in a staggered configuration.

A telecommunications cable comprising:

• a plurality of twisted pairs of conductors arranged around and running along an axis;
• and
• a cable jacket surrounding said twisted pairs, said jacket comprising an outer surface wherein said outer surface defines a tube having a helical centre path arranged around and running along said axis.

A telecommunications cable comprising:

• a plurality of twisted pairs of conductors arranged around and running along a first axis;
• and
• a cable jacket surrounding said twisted pairs, said jacket comprising a protrusion arranged around and running along said jacket, wherein said protrusion is arranged helically around said first axis.

A telecommunications cable comprising:

• a plurality of in parallel twisted pairs of conductors, wherein each of said pairs has a constant twist lay and follows a helical path along said axis, said path having a variable pitch.

A telecommunications cable comprising:

• a plurality of parallel pairs of conductors arranged along an axis;
• a cable jacket, said jacket when viewed in transverse cross section comprising an oblong part surrounding said helical pairs and a protruding part extending from an outer surface of the jacket;
• wherein said oblong part rotates along said axis and said protruding part winds about said axis and further wherein a pitch of said winding protruding part is variable versus said rotation of said oblong part.

A telecommunications cable comprising:

• four twisted pairs of conductors arranged around and running along an axis;
• wherein, when the cable is viewed in transverse cross section, a first distance separating a first of said twisted pairs and a second of said twisted pairs, said second pair and a fourth of said twisted pairs, and said fourth pair and a third of said twisted pairs is greater than a second distance separating said first pair and said fourth pair and said second pair and said third pair and less than a third distance separating said first pair and said third pair.

A method for fabricating a telecommunications cable comprising the steps of:

• providing four twisted pairs of conductors;
• and
• placing a separator spline between said twisted pairs, said spline comprising a principal dividing strip and a first subsidiary dividing strip attached longitudinally along a first side of said principal dividing strip and a second dividing strip attached longitudinally along a second side of said principal dividing strip, said spline separating said four twisted pairs such that they are arranged asymmetrically.
