>From what I have read about COAX I understand that COAX is better
than twisted pair because of the electronic shielding effect provided
by the outer conductor.  In some environments COAX must be used in
order to prevent inductive interference due to spurious RFI emissions
and other frequencies.  In the case of twisted pair, the more twists
the better when it comes to preventing interfering induction.

A drawback to COAX is that it tends to be persnickity over such things
as impedence mismatches when connecting to different types of of
COAX cables.  Usually this problem can be overcome by installing
some impedence transformers and such.  I must admit that I don't have
much knowledge and understanding in this matter at all.  I'm just
reporting on some stuff I have read.

Fiber-optics connections are an alterative to twisted pair and COAX.
They are said to be best for preventing inductive interference.

If anyone knows of an authoritative URL on this subject plese post.
