Here is an interesting/informative video presentation that speaks predominantly to the defense market, system performance, and future of optics. With what we know about Poet - we can see why Poet could be a game changer.
The speaker provides a good example talking about power consumption at about 5:15 of the video.

Fiber optic interconnect offers enormous bandwidth with all the advantages of space, weight, power, EMI immunity, and now reliability to embedded systems. The challenge today is migrating from proven copper interconnects to embedded fiber optic components. This presentation provides a view of rugged optical modules for embedded defense applications.
