| magnitude of the signal power coupling from a disturbing symmetric pair at the near end, measured at the far end, to a disturbed symmetric pair measured at the far end where: is the output power of the disturbing pair at the far end (W); is the output power of the disturbed pair at the far end (W); is the input power of the disturbing pair at the near end (W); is the attenuation of the disturbing pair (dB).
Note 1 to entry: The equal level far-end crosstalk is related to far-end crosstalk by the attenuation of the disturbing symmetric pair in the measured cable length. Note 2 to entry: The equal level far-end crosstalk is expressed in dB. Note 3 to entry: The content of this terminological entry is based on IEC 61156-1:2023, 6.3.7. |
