A number of previous articles have pointed out various good strategies
for success with thin Ethernet. But two critical points have been left
unclear, at least in my mind:
1) The cable must be 50 ohm coax. (in our shop at least,
75 ohm cable is commonly used for video signals)
2) The cable MUST be terminated with 50 ohm resistors.
(some previous discussions have alluded to
leaving the cable open at the ends)
We have only used thin cable so far and we are getting good service
from it, but we are starting to see 2-3% of the packets have errors
now that we are running 400 feet of cable. Our other big lesson so
far is that connector construction is extremely critical. It must
be done well.
