SIlly topic. Will they negotiate to 100Mbit or is there a chance that they will negotiate to 1Gb?
I don’t see how they could negotiate 1gig with only half the connection present. There’s probably a balun or something that lets you try and cram a 1ghz differential signal across only four wires, but it’s probably cheaper to redo the run.
Nope. 1Gbps requires 4 pairs
You can get gigabit over a single pair but its not used in computing AFAIK. You’d need 4 pairs to negotiate gigabit.
Ethernet over twisted pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers.
Early Ethernet had used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and its successors 100BASE-TX, 1000BASE-T and 10GBASE-T, supporting speeds of 10, 100 Mbit/s and 1 and 10 Gbit/s respectively.[a]
All these standards us...
