Well, you'll have to have an A/D converter somewhere in the line. If the
optical cable is digital, then the A/D converter would live in the
microphone. But there isn't any way to remove the A/D conversion. You
wouldn't need a D/A converter unless you wanted to playback.

Digital versus analog is orthagonal to electrical versus optical.
