Re: XAUI rate on UTP CAT 5 transmission experiment.
Benny,
Just a thought. What is the EU equivalent of the FCC? What kind of
radiation might these cables generate?
I appreciate your provocative submission. Cables are of course one major
part of the equation. Connectors are also important. Have you tried this
with RJ-45 connectors? :-) What would you suggest which is a low cost
connector, in keeping with the CAT-5 thought?
