SoundBlaster X-Fi

I got a new High Spec PC from Dell and I got the SoundBlaster X-Fi upgrade and it looks like this one...
Sound Blaster X-Fi Xtreme Gamer

but I also have what looks like an input and output for fibre optic cables as there a red light on one of them I have to post a picture tonight but the chip board look like the above apart from the two extra ports.

can some one tell me what one this is so I can download the correct drivers for it?

Im looking at trying to put my xbox as a input for the sound card so I can play it from my PC monitor and sound card.

Update dell call it: -
Sound Blaster® X-Fi Xtreme Music PCI Soundcard

but the Music still looks the same as the above image but still with two extra ports

:Update:

I still need to find out what card it is?

but it dose have a Optical In and Opctical Out Port's which looking on the soundblaster site there is no card with this featur ?????

OK here is the picture of the back of the system, i pluged in a optical cable to show you (the light dose not show well but there is a red light coming out the end of the cable).


But I still cant find a Sound Card by sound blaster that has optical in/out
