FEXT stands for Far-End Crosstalk; how is it defined?

Explanation:
FEXT is the crosstalk that appears at the far end of a cable when a signal is transmitted on another pair. It is defined as the unwanted coupling observed at the far end, typically expressed as a ratio in decibels relative to the transmitted level. This distinguishes it from near-end crosstalk, which is measured at the transmitting side. The other terms aren’t standard or apply to different concepts: near-end would be Front-End Crosstalk; there isn’t a common term like Frequency Ext Crosstalk; and Fiber End Crosstalk would refer to fiber, not copper pairs. So the description of crosstalk measured at the far end due to signals on other pairs best defines FEXT.
