What does the term “NEXT” mean?

Marco Thull | 5. July 2019

You are here:

The NEXT value indicates the extent to which the cross-talk between two neighbouring core pairs in a cable is suppressed. Cross-talk is due to electromagnetic fields that occur as a result of signal transmission and are induced into the other core pair. The Near End Crosstalk value indicates how strongly the signal of a core pair is induced into the other core pair. It is indicated as the logarithmised ratio of signal power in the sending core pair to the receive power in the receiving core pair in decibels (dB).
