usb vs toslink?

My PC is about 100 feet away from my DAC. If I am not mistaken, Hagerman usb converter uses usb cable not CAT5. So, the 15-foot limitation on usb cable length would be an issue. (The optic usb cable is very expensive and such it's out of question.) Is there any alternative to it?

What do you think of Squeezbox which uses CAT5. (It costs more than double the Hagerman's usb.) Any other inexpensive choices?

why the 15 ft limitation for usb cable??
