My tv has an optical as well but the stero unit doesn't. What will the other end of the optical look like?
There is a good guide to connections over
here @ lifewire #07 is going to be the optical cable and socket on both ends.
Have a look at #08, those are the analog RCA cables and jacks, some TV also have those so that will be another option for good old stereo L and R connections into your stereo. If your TV only has the optical output, you can get a converter like
this one which will convert to stereo out.
