Abstract
Twisted pair communication cables incorporating twisted pair separators are described. A cable may include at least one twisted pair of insulated conductors extending lengthwise. A dielectric separator may also extend lengthwise within the cable, and a cross-section of the separator may include at least two portions positioned at an angle to one another. The portions of the separator may form one or more cavities in which one or more corresponding conductors of the twisted pair may be positioned or situated. A jacket may then be formed around the twisted pair and the separator.
Claims24
A cable comprising:
- a twisted pair of insulated conductors extending lengthwise;
- a dielectric separator extending lengthwise with a cross-section comprising:
- a first portion positioned between the insulated conductors of the twisted pair, the first portion comprising a plurality of projections, each of the projections extending from the first portion towards one of the insulated conductors;
- and
- a plurality of additional portions extending at respective angles from the first portion so as to define respective cavities into which each of the insulated conductors is positioned;
- and
- a jacket formed around the twisted pair and the separator.
A cable comprising:
- a twisted pair of insulated conductors extending along a longitudinal length of the cable;
- a separator helically twisted with the conductors and extending along the longitudinal length of the cable, a cross-section of the separator comprising:
- a first portion positioned between the conductors;
- and
- a plurality of second portions extending at respective angles from the first portion,
- wherein the first portion and the plurality of second portions form respective cavities in which the insulated conductors are situated;
- and
- a carrier layer embedded in the first portion, the carrier layer comprising at least one of (i) one or more strength members, (ii) water swellable material, (iii) flame retardant material, (iv) smoke suppressant material, or (v) electrically conductive material;
- and
- a jacket formed around the twisted pair and the separator.
A cable comprising:
- a twisted pair of insulated conductors;
- a dielectric separator positioned between the insulated conductors of the twisted pair, the dielectric separator further defining longitudinally extending individual cavities in which each of the insulated conductors is positioned;
- and
- a jacket formed around the twisted pair and the separator,
- wherein the dielectric separator is either scored or notched at a plurality of locations along its longitudinal length.
