Such exists. It's called TOSLINK. It's used for digital audio but should be
adaptable to other sorts of digital optical communication.

Hello,
I am trying to configure motors in pncconf with 7i76 board,
I have selected the tab 'connector 2' and then selected a X-Axis StepGen
which shows a StepGen-A and DirGen-B, but testing the motor with the
panel it doesn'tg move. is this the right thing to do?
Thanks

Somewhere near the bottom of my junkbox is an envelope with a pair of

Indeed, and also means that the drive is probably ready to move, but
not seeing step-pulses.
With the test window open, open a terminal and type

I think this is the problem.

It is rarely necessary to make the step and space lengths as short as
possible, you tend to run into phy
If you can get the surface clean enough for it to stick, packing tape works
works ok for patching up holes a an old way cover. (for "temporary")

You are right the noise impunity could be VERY good. But I bet 99% of
users simply tie one end to ground and send

Years ago when I thought fiber might catch-on I grabbed some 62.5/120
plenum fiber at Boeing Surplus.
I got as far as connecting a 10-base2 card to a fiber converter fishing
out both ends of the fiber on the reel
and terminating with 3M (?) hot-melt end. It worked nicely but 10 Mhz
isn't straini
Fiber was 200 megabit, 100 each way. Had to have two fibers for full speed.
Then came 100 megabit full duplex wired Ethernet, matching the speed of fiber.
For some reason companies quit working on fiber to speed it up as an
alternative to Ethernet.
Then came gigabit, 2.5 gigabit, 5 and now 10 gi
