3.1.1.1 Fully populated pin assignment

For fully-populated pin assignment, as shown in Figure 5, Ports 1-2 are grouped into Pair 1, and

Ports 3-4 are grouped into Pair 2, …, etc. Figure 6 shows the corresponding SDD for pair 8 (or

Ports 15-16), where the insertion loss (IL), return loss (RL), and crosstalk can be clearly seen, and

are summarized in Table 1.

The impedance and trace delay values for each of the 15 differential pairs are shown in Table 2.

Figure 7 shows the return loss (RL) comparison with the IEEE802.3ap spec for the center pair 8.

Figure 8 - Figure 11 show the power sum and insertion-to-crosstalk ratio (ICR) profile comparison

with the IEEE802.3ap spec of NEXT and FEXT, respectively.
