IT3 Series High-Speed(10
Differential Far-End Crosstalk (FEXT)
Insertion-Loss-to-Crosstalk-Ratio (ICR) for FEXT
Low far-end crosstalk at the center pair from surrounding 8 aggressors is observed. Even lower crosstalk
can be achieved by skipping pins.
The insertion-loss-to-crosstalk-ratio (ICR) for 8-aggressor FEXT meets the extrapolated IEEE 802.3ap
specification up to 12GHz.
