far end crosstalk

far end crosstalk
= far-end crosstalk; = FEXT
перекрёстные наводки на приёмном конце линии [кабеля на основе витых пар], параметр FEXT
определяется аналогично NEXT, но в формуле 10log РВЫХFEXT фигурируют мощности выходного и наведённого сигнала на другом конце линии. Вследствие затухания FEXT увеличивается при увеличении длины кабеля, т. е. для разных по длине отрезков кабеля одинакового качества значения FEXT будут различны. Поэтому значение FEXT не имеет смысла без указания затухания на отрезке кабеля, где оно было измерено
