Abstract
Shielded twisted pair communication cables are described. A cable may include at least one twisted pair of insulated conductors, and an outer circumference may be defined by the twisted pair along a longitudinal length of the cable. A shield may be formed around the twisted pair, and a jacket may be formed around the shield. Additionally, a dielectric film may separate the insulated conductors of the twisted pair, and the dielectric film may extend beyond the outer circumference of the twisted pair and contact the shield.
Claims19
A cable, comprising:
- a twisted pair of insulated conductors, wherein an outer circumference is defined by the twisted pair along a longitudinal length of the cable;
- a shield formed around the twisted pair;
- a dielectric film separating the insulated conductors of the twisted pair, the dielectric film extending beyond the outer circumference of the twisted pair by a distance of at least approximately the diameter of one of the insulated conductors and said dielectric film comprising an end portion having a “T” or “L” cross-sectional shape that contacts the shield;
- and
- a jacket formed around the shield.
A cable, comprising:
- a twisted pair of electrical conductors;
- a shield formed around the twisted pair;
- a dielectric separator positioned between the electrical conductors of the twisted pair, the dielectric separator extending beyond the twisted pair and comprising an end portion having a “T” or “L” cross-sectional shape that contacts the shield, wherein a separation distance between the shield and the twisted pair is maintained by the dielectric separator;
- and
- a jacket formed around the shield.
A cable, comprising:
- a plurality of twisted pairs of conductive elements;
- a plurality of shield layers, each shield layer formed around a respective one of the plurality of twisted pairs;
- a plurality of dielectric films, each dielectric film positioned between the conductive elements of a respective twisted pair and extending beyond the twisted pair to provide separation between the twisted pair and its respective shield layer, wherein each dielectric film further comprises an end portion having a “T” or “L” cross-sectional shape that contacts the respective shield layer;
- and
- a jacket formed around the plurality of twisted pairs and the plurality of shield layers.
A cable, comprising:
- a plurality of twisted pairs of conductive elements;
- a separator positioned between at least two of the plurality of twisted pairs, the separator comprising one or more sections of electrically conductive material;
- a dielectric film separating the conductive elements of one of the twisted pairs, the dielectric film extending beyond an outer circumference of the twisted pair and comprising an end portion having a “T” or “L” cross-sectional shape that contacts the separator to maintain a separation distance between the twisted pair and the separator;
- and
- a jacket formed around the plurality of twisted pairs and the separator.
