They dont use Fiber, it is a marketing gag. Depending on subscriber density in your area your experience may range from great to omg i want to kill myself.
If you need tv you should get a FIT package but since you dont seem to speak german i dont see how much good that would do you.

If your main priority is an internet connection you should get the Fiber Power package for 12 months ((22,90 Euro + 1,25 Euro) * 12 months). All UPC packages come with a yearly 15 Euro (15/2=1,25) service fee. Dont get the 24 month contract because saving (6*(22,90 - 19,90))= 18 Euros is definitely not worth it. (Most definitely you will either get a better package after 12 months from UPC or a competitor)

There dont seem to be any rebates for students anymore, your university may know more about that.
If you want to access english content you could get a Netflix (USA) subscription and use tunlr.net free DNS servers (squid reverse proxy) for just 8 USD per month and access 10k+ movies and tv shows. The AppleTV and PS3 both offer great Netflix integration.
