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.
Claims12
A communication plug for connection to a communication cable having a plurality of twisted pairs of conductors, said plug comprising:
- a housing including a cavity for receiving the communication cable;
- a plurality of contacts at least partially within said housing;
- and
- a noise suppression core at least partially within said cavity, said noise suppression core including a plurality of pathways, each of said plurality of pathways adapted to at least partially surround a respective one of the plurality of twisted pairs of conductors.
A communication cord, comprising:
- a communication cable having a plurality of twisted pairs of conductors;
- a communication plug connected to said communication cable, said plug including a housing having a cavity for receiving said communication cable;
- a plurality of contacts at least partially within said housing and connected to respective said conductors;
- and a noise suppression core at least partially within said cavity, said noise suppression core including a plurality of pathways, each of said plurality of pathways adapted to at least partially surround a respective one of the plurality of twisted pairs of conductors.
A communication connector for connection to a communication cable having a plurality of twisted pairs of conductors, said connector comprising:
- a housing including a plurality of contacts at least partially within said housing and an aperture for receiving the communication cable;
- a printed circuit board at least partially within said housing and having a plurality of traces for connecting said plurality of twisted pairs of conductors with respective said plurality of contacts;
- and
- a plurality of noise suppression cores connected to respective said plurality of traces for suppressing noise on said twisted pairs of conductors.
The communication connector of claim 12, wherein said connector is at least one of a communication jack and a communication plug.
