Hi

Has anybody run Ethernet (10-100 Mega Bit) through any other connector,
other than the standard RJ45?

Thanks.

Well, you can run it on anything that meets the Cat-5 specs (and some
things that aren't, cf. the barbed wire discussion that comes up
frequently), but then it isn't Ethernet, is it?

What problem are you trying to solve? What's wrong with RJ45 in your
application? There are (for instance) weathertight RJ45 connectors...

Many PCMCIA ethernet cards use non-standard connectors, to connect the cable
to the card.

Well, if you were doing a lot of wiring, and wanted to save money, I
don't see why you couldn't use telephone type connectors. Just make
sure you are consistant and get the polarity correct. You might want
to avoid the center two contacts in case soembody plugged in a single
line phone. And make the next two contacts be the inbound signal. I
had thought of that so that I could wire my home with jacks, but then
decided I didn't care if I just had wires coming out of holes in the
walls. The official RJ45 wall jacks are a lot more expensive than
phone jacks.

If you really want to save money use four line phone jacks.
That is, ones that aren't Cat 5 certified but will probably
work fine for 10baseT, and if you are a little careful in
wiring them at 100baseTX.
