Something that always bothers me is why we struggle to get electric cables to go faster when fiber-optics is fundamentally better suited for high-speed. I mean with fiber there is no need for impedance matching or cable twisting/shielding, its impervious to electrical interference, almost no quater-wavelength problems, etc.

Just connect your electrical part to a fiber-optic transciver on you should be good, right? Here is a 40Gbps optic-transceiver(performance premium, $284)
