I presume you are talking about 4 wire Ethernet because we do GigE all the time on copper. GigE uses all 8 wires and has data flowing both directions.
100 Mbps E uses 4 wires (2 pair) with TX on one pair and RX on the other pair. GigE uses advanced modulation methods as well. Does that help? From: Jesse DuPont Sent: Monday, January 14, 2019 3:58 PM To: AnimalFarm Microwave Users Group Subject: [AFMUG] Ethernet 100M Copper Limit I figured this was the best place to ask this question: What is the primary reason for the 100M limit on copper Ethernet links? Is it related to bit errors/SNR or is there a timing element involved? Something else?
