powersum NEXT (PSNEXT)

The Powersum NEXT (PSNEXT) forms the power sum of the near-end crosstalk.

Relationship between PSNEXT and PSELFEXT

The PSNEXT value is the sum of all interference signals that are coupled into a conductor pair. PSNEXT is very close to the actual operation when data is transmitted over all pairs of conductors. This value is particularly important for four- and higher-pair balanced cables. With two-pair cables, PSNEXT corresponds to Near End Crosstalk (NEXT); with higher numbers of conductor pairs, the differences become greater and greater, since the interference signals from several conductor pairs are interspersed in a conductor pair.
