How to choose a good fiber optic cable??


Does anyone have a handle on the science of what factors determine a good fiber optic cable for audio? I'd like to make use of both digital inputs on the Dlink III and recognize that the fiber input has more jitter than coax. What would the checklist of features be to get the best possible outcome out of a fiber optic interconnect purchase?

Glass is best but I've never heard a toslink that could stand up to a decent SPDIF cable.

Coressence: The glass toslink is flexible but dont get crazy with any sharp bends. A gentle "C" or "S" shape will suffice. Do not step on them either. Only buy as much as you need ...so measure carefully. Great for HDTV audio out cable.
Since I don't have any audio equipment I can use fiber with, I was wondering what types of connectors and fiber is used with audio gear. Is it similar to data as in 62.5 or 50 micron? I figure it must be since it's so readily available. If you're concerned about bend radius, just get armored fiber and you won't be able to exceed the bend radius.
For what it's worth, I tried one of those uniqueproducts cables. I got it on ebay and paid $29 for it shipped and that was a deal. It blew the $80 cable that I got at my local boutique shop out of the water with more detail and better mids. I will be ordering more.

I'm sure that there are better out there, but I don't know about them and ignorance can be bliss.
