I'm searching for sources for Ethernet and/or 802.3 compatible network
hardware -- low-level stuff, specifically:
- coaxial cable
- coax connectors/terminators
- isolation transformers
- dc-to-dc converters.
Please email to me, if there is interest I will summarize and post.

IF you are looking for something small (i.e. to put on a circuit board) there is a DC converter by Reliability Inc. which is either +12 to -9 or +5 to -9 in a 28pin dip package. We have been using these for about 3 years now without any problem. Also we use a 16pin dip isolation transformer by Pulse Engineering. PE-64102 is the part we use. This is also second sourced by Nano Pulse Industries Inc. There is some really new neat stuff, very integrated by Fujikura America. It is a board mountable module about 1" square, which is an entire transciever (isolation, DC2DC and the Driver/Receiver chip, and oscillator also). I have tested these, and have had no problem, but have never used them in any application. There are 2 large manufacturers of cable and connectors, both have lots of kinds, and lots of prices. They are "Gore" and Pasternack Enterprises, Pasternack may actually just be a wholesale house for lots of other manufacturers. Address for all these places: Reliability Inc. Pulse Engineering Inc.
