I'm not sure fiber optics are particularly viable in the next 5-10 years as interconnects between hardware components. Adding photonics to a hardware component increases size and cost fairly significantly, which is why you don't see many fiber optic interconnects yet, even for applications where cable size is important. Moreover, to get the kind of miniaturization you would need for a cell phone, you're talking on-chip photonics (diodes and photodetectors integrated into the IC itself), which still looks like it's in the early R&D phase. Of course, most of this is probably because copper is still doing just fine in terms of bandwidth. Though some big issues with forcing huge bandwidth over few traces are latency and the additional circuitry needed to translate the signal into the actual components needed to drive RAM chips or a CPU. |

It's out of R&D and entering production.
