Here at RIT we have had the THICK Ethernet installed for some time.  We had
also been using (but are slowly phasing out) the IBM 327x type equipment
tied to controllers with RG 62 A/U cable.  I had always thought that this
cable was 50 Ohms, but after looking in a Belden catalog, the specs show
that the cable is in fact 48 Ohms or was it 48.? Ohms.  Well either way
I know that the Thin Ethernet cable is supposed to be 50 Ohms as is it's
bigger fatter brother.

Just about every office in our computer department has the RG62A/U running
from it to a patch panel in the CPU room.

I will probably try this out anyway, but am looking to see if anyone has
done this before.  That is using the RG62A/U cable for Thin Ethernet?

Will the slight difference in OHMS have a detrimental affect on the
Ethernet?

When looking for THIN ETHERNET supplies in catalogs, I have only
come across cable with stranded center conductor.  I am wondering if
there is any THIN ETHERNET around with a SOLID COPPER center
conductor as then I could use BNC "Fast Fit"/"Twist On" connectors.
