Default Optical and Coax cable length?

Do you feel that 1M of optical or coax digital cable is not long enough? Or is it too long already??? Please let me know and we will see about getting the cable with the "right" length in stock.

If you are interested in Analog Interconnects, you can also post and respond to the poll here too.

Regular optical - up to 10m
Quality optical - up to 15m
Coax - don't know but I've been using 10m for my PC-DAC connection and although it works - from time to time DAC generetas failures

Hummm, it is kinda odd that a post from another poster doesn't seem to show up...

Just to let everyone know, I vote for 1M myself :P

Ahhh, I see, I was just a little confused when I see the email notification without seeing anything on the thread.


Thanks

Will your next poll be about what ladder height is best?

I have a 1 m optical cable that is just too short (the cable only just makes it but with the strain the connectors are pulled slightly - intermittent loss of connection), and I can't move the components closer together. Here a 1.5 m length would be great, but I just have never got around to it. Using a coax currently. But for the fibre link, length should not be an issue, unless there is an interaction with the nominal wavelength of 650 nm & the maximum output power of the laser diodes. I have never looked at the standard re the TOSLink interfaces. Will be interesting to know what the limitations and recommended minimum and maximum lengths are.

Fibre can be too short, extra modes cause too much light to couple and the receiver overloads with pulse distortion.
1.5 to 2m is about right for general purpose

@davidsrsb - exactly. And reflections can occur at the coupling points. Though error correction should cater for that.
P.S. After looking at a brief synopsis of the standard, I see they say that the standard commercial product is a high quality plastic "pipe"; WT*! proper silica/glass is not expensive, and is a much better medium. The plastic material has an extremely high attenuation rate compared to plastic.
