Differential Insertion Loss
Differential Return Loss
Differential Near-End Crosstalk (NEXT)
The differential insertion loss is less than -2dB up to 12GHz.
The connector-only differential return loss for the center pair meets the extrapolated IEEE 802.3ap spec up to
12GHz. (The attenuation of PCB traces in the channel will give an even larger margin.)

The near-end crosstalk at the center pair from surrounding 8 aggressors is shown below. The NEXT is not as
critical because TX and RX can be grouped into separate wafers.
