This standard is applicable to the measurement of near-end crosstalk attenuation and far-end crosstalk defense of communication cables of manufactured length by comparative method. The test frequency is 0.8kHz ~ 1MHz, if the performance of the instrument allows, it is also applicable to a higher frequency range.
