I know about standard IEEE802.3af.
But this morning I had this idea:
Why not use AC.
And then for example 20kHz, and over each twisted pair, so it does not radiate.
In the switch we can have a simple ring core with windings with all the same
number of turns, one winding for each switch output, one for input, these
transformers would be bidirectional, so it makes no difference which input
is the feed as long as there is one.
Windings could be fitted with a fuse.
In the Ethernet appliance a transformer can then transform to any needed voltage.
So setup (and fuse scheme) a bit like a normal house wiring.
Of course there is a max current these little connectors can do, but how about
using say a 20KHz (above audio range) sine wave.
It is very easy to generate too.
