PRODUCTION DATA
For optimal AEQ performance and error free operation, the end-to-end transmission channel (Including cables, connectors, and PCBs) needs to meet insertion loss, return loss (impedance control), and crosstalk requirements given in Table 7-6 and Table 7-7. Poor impedance control or insertion loss of the transmission channel and poor channel to channel isolation (low IL / FEXT) may result in significant reductions in the maximum transmission distance.
