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?
