First Claim
Patent Images
1. A multi-pair cable, comprising:
- a) a cable core including a plurality of twisted pairs, each of the twisted pairs including a first conductor surrounded by an insulating layer and a second conductor surrounded by an insulating layer, the cable core defining a central axis;
b) an inner jacket surrounding the cable core, the inner jacket being made of an insulating plastic material, the inner jacket having an interior surface and an exterior surface, the inner jacket including channels formed in the interior surface of the inner jacket; and
c) an outer jacket surrounding the inner jacket, the outer jacket having an interior surface and an exterior surface, the interior surface of the outer jacket contacting the exterior surface of the inner jacket, the outer jacket including channels formed in the interior surface of the outer jacket;
d) wherein each of the inner and outer jackets is concentrically located in relation to one another.

Abstract
A multi-pair cable having a double jacket, including an inner jacket and an outer jacket. The inner and outer jackets each including channels formed on an inner surface. The channeled double jacket of the cable reducing the occurrence of alien crosstalk between adjacent cables by reducing the overall dielectric constant of the cable and increasing the center-to-center distance between adjacent cables. The channeled double jacket of the cable still accommodating existing standard cable connectors.
