    Can a lower yield of these be used for Optical Thunderbolt? Even 1/20 of it, 80Gbps will do.

    They're billing it specifically as "The Next Generation Optical Connector ", not just as a new interconnect. I'm guessing that they've bonded the laser emitter and receiver to the ends of the fibre itself, to cut transmission losses from the fibre/port interface at each end, and to allow each fibre to be 'tuned' at the factory to compensate for any slight variance in each. If the each cable is characterised, then that's going to be a real pain for splicing your own fibre (you'll either need to buy cables already manufactured to the right length, or have the cable reanalysed after every splice), but for that massive increase in data rate companies may happily eat the cost.

    Not necessarily, for example: Folding@Home - Vast compute power, extremely slow to get the data from one server to another.

    True, but that's neither HPC nor supercomputing - that's distributed computing, and only suitable for selected workloads.

    1.6Tb/s sure is nice, but WAYYY too expensive atm.

    200GB/sec makes remote DMA a reasonable option - this might completely change how people look at HPC server architecture!
