powersum FEXT (PSFEXT)

The Powersum FEXT (PSFEXT) forms the power sum of the far-end crosstalk. It is the sum of all interference signals that are coupled into a conductor pair. In the case of two-pair cables, the PSFEXT corresponds to the Far End Crosstalk (FEXT); with higher numbers of conductor pairs, the differences become greater and greater, since the interference signals from all conductor pairs are interspersed in a conductor pair.
