I have always found AT&T ST to perform the best. There is not a lot of money to be made in selling glass cables. Glass was perfected years ago. If you can not find a cable. Call your local electronics supplier. Tell him what you want (multi or single mode fiber) with ST connectors. Request a hot fusion and the best polish that they can do. It will cost a lot less than you might expect.
What Ever Happened to ST Optical?
Based on the hype several years ago, I opted for the AT&T "ST" optical connection between my CD transport and processor. I've generally been satisfied with it over the years, but damage to the cable (oops) is forcing me to do a replacement. Is ST optical still a viable choice, or is coax better? Seems to be far fewer suppliers of the ST thes days-- my previous was XLO and they don't list it on their website anymore.
