There are nice 10bT to fiber (fibre in the UK) converters in the BlackBox catalog (catalogue). You chould put these oh-so-close to the router or switch in the equipment space - maybe even braid the 10bT cables to confuse any listeners there. Then 10bF cards in the machines ensure no EMI emitted in the unsecure area. - Jy@ On Tue, 7 Sep 1999, David Miner wrote: > In regards to the other problem of EM from the UTP, have your uses given > thought to running the lines through shielded conduit.
