Optical cables aren't susceptible to interference.Coax cable has wider bandwidth.A couple of inexpensive but well thought of coax cables are Wyde Eye(Amazon) and the $12.99 coax from Monoprice.Coax measures and performs optimally at 1 to 1.5 meter lengths.You can research that further if it's of interest:)
Optical cable should be sturdily built,both the plastic and glass cables tend to crack in the super inexpensive brands that can be had for just a few $.Something from Audioquest,Kimber,Pangea should be fine.
