ATT / ST Optical Cable?????

Does anyone know of any aftermarket ATT ( using ST connector)optical cables designed specifically for audio? I am having a hard time finding one. Everything that I have seen online or on Ebay are ST cables for data transfer used in the computer industry. Currently I am using one of those between my transport and DAC. I haven't noticed anything particularily wrong with the sound when using this hookup, but I believe there must be something better than what I am using. I would think that there would be more audiophile companies making ATT cables, considering what a huge market cables are today.
