Does this cable exist ?

I'm trying to find a cable that has optical digital on one end, and coaxial digital on the other end.

I know there are converters, but I'd rather find a cable, if possible.

Thanks.

No, it's not possible for this to just be a cable. Digital optical is fiber, coaxial is metal wire. They don't work the same, which is why you actually need a device to receive one format, and output the other.

It requires electricity so at the very least you need a transformer plugged to the wall no matter how small you make it. If you cracked one open you could possibly use electrical tape to bind the circuitry tightly to a wire?

Can't happen. One is optical (light), the other electrical (wire). That's why they make "converters".


EDIT:
Also, they are not bidirectional. Compare the link above to the link below.

Okay.... there may be some that are bi-directional with a switch.


Just making the OP aware.


EDIT:
Surprised it wasn't pointed out that the labeling on the link above is not accurate.
Both coax and optical are S/PDIF.

Also keep in mind some are PCM (2ch music ) only whereas some others are 5.1, Hi-res sampling rates, etc..

True for S/PDIF to analog converters.

Not so sure about optical to coax or coax to optical. S/PDIF to S/PDIF should carry the PCM or bitstream signal supported at each end of the connections (S/PDIF compliancy of course.)

Thanks, but I am just trying to follow along. Would never have dreamed of an optical to a coax. Most of those converter type boxes are not worth a darn either, correct?

No, incorrect. They work.

I've been using one from Monoprice for quite a few years.

Cool. Just seems like it would not be possible to work. That is why I come here and learn something new every time.

But it is possible!


It's not a new gadget.



Ask before posting "???????????? "
It may be misinterpreted.

It's an incredibly simple circuit either way. ie O-C or C-O.

That why the prices are $10-15 USD. The plastic case and power supply are 85% of the cost.
