Alca-Lu runs 16.4 Tbps, 2,550 km. test

In a post-deadline paper presented at OFC/NFOEC in San Diego, Alcatel-Lucent discussed how it used polarization division multiplexed quadrature phase-shift keying (PDM-QPSK) to send serial 100 Mbps signals in 16.4 Tbps stream for a distance of 2,550 km. over a single fiber. While such a signal may be required simply to send the amount of information contained in that particular acronym, there probably isn't a short-term commercial requirement for it, as is the case with most of the experimental stuff presented at OFC/NFOEC. But, cool nonetheless.
