Crosstalk Performance: Cables, Connectors, Cords

Historical Crosstalk Performance: Historically, crosstalk was attributed primarily to the cables, but as LAN speeds increased and the cables improved, other channel components started to contribute to the crosstalk performance. The cumulative effect became known as Composite Crosstalk, and the primary channel components that contribute to this are the cords, connecting hardware and cable. It […]

The Methodology for Crosstalk Measurement

Cabling Crosstalk Measurement As mentioned in our previous blog, Crosstalk is probably the most important characteristic of copper cabling for high speed data applications. It can be described as the undesired energy appearing in one signal path as a result of coupling from other signal paths. Signals induced from crosstalk can also be significant enough […]
