The problem with COAX is that it only supports 10 MBit Ethernet.
FTP/STP should not suffer under interference.
(foiled TP ... every pair is sourrounded by a metal foil
STP same as FTP + outer metal conductor around all pairs)
COAX is not used in the networking section for years.
The only advantage is that you can make a bus, and connect many stations
onto the same cable. (but beware ... they are all in the same collision
domain !!!!)
With TP you can either connect 2 hosts with a X-over TP cable, and use full
duplex (send and receive at the same time) or use a hub or switch to
connect them)
The hub is cheaper, but than all stations are still in the same collision
domain.

Sure ... they 100% prevent interference ... they work with light :)
BUT ... They are _EXTREMELY_ expensive !!!
You surely will not want to connect 486 with fibre, where the cableing +
the NICs will cost more than a new athlon 800 MHz system !!!
