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.
Claims6
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,
- wherein said plurality of pathways includes a first closed pathway, a second closed pathway and a web connecting said first closed pathway and said second closed pathway, and
- wherein said web includes a first open side and a second open side, said plurality of pathways further includes a third open pathway adjacent said first open side, said first closed pathway and said second closed pathway, and a fourth open pathway adjacent said second open side, said first closed pathway and said second closed pathway,
- said third open pathway and said fourth open pathway extending an entire length of said noise suppression core.
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
- wherein said plurality of pathways includes a first closed pathway, a second closed pathway and a web connecting said first closed pathway and said second closed pathway, and
- wherein said web includes a first open side and a second open side, said plurality of pathways includes a third open pathway adjacent said first open side, said first closed pathway and said second closed pathway, and a fourth open pathway adjacent said second open side, said first closed pathway and said second closed pathway,
- said third open pathway and said fourth open pathway extending an entire length of said noise suppression core.
