Behavior of Crosstalk Loss for Adjacent Pairs at Low Frequencies

Measurements at the Northern Electric cable plant in Lachine [2] and elsewhere [3],[4] showed that at low frequencies near-end crosstalk loss (NEXT) and far-end crosstalk loss (FEXT) for adjacent pairs do not have slopes of 15 dB/decade and 20 dB/ decade, respectively. In this paper an approximation predicts a slope of 5 dB/decade for NEXT and long cable and 10 dB/decade for FEXT.
