Abstract
Alien crosstalk suppression cores are used to decrease alien crosstalk in communications channels. Electrical communication cables may be provided with alien crosstalk suppression cores. The alien crosstalk suppression cores, which may be ferrite suppression cores, are placed separately on some or all of the twisted pairs within a communication cable. The alien crosstalk suppression cores reduce ANEXT and AFEXT in high-frequency communications when communication cables are installed near one another. Alien crosstalk suppression cores may also be incorporated into other communication channel components, such as on a PCB within a communication jack.
Claims8
A printed circuit board for use in a communications connector, said printed circuit board comprising:
- a plurality of pairs of conductive traces;
- and
- at least one alien crosstalk suppressing film disposed proximate one of said plurality of conductive traces to reduce alien crosstalk between communication channels.
A communication cable comprising:
- a cable body containing a plurality of conductive pairs;
- and
- connectors terminating ends of the cable body;
- at least one of the cable body or connectors containing a plurality of alien crosstalk suppression cores, each of said alien crosstalk suppression cores surrounding at least one pair of the plurality of conductive pairs and being mounted within a housing that separates the alien crosstalk suppression cores;
- wherein each of the alien crosstalk suppression cores contains a plurality of sections installed around the respective conductive pair.
