How do I tell if an audio receiver has Optical Cable TOSLINK?

So I want to use optical cables to connect my blu-ray to audio receiver which then connects to two speakers.

However, for whatever reason, when people post equipment to amazon or newegg, they don't put up good pictures. From the spec reading I can't tell if they have optical digital audio output or if they do not.

For example, from the picture I can tell there looks to be an output for optical, but it doesn't mention it at the bottom:

How do you tell??? Or can I do without it by using simple RCA cable plugged into a coaxial on the blu-ray?
