Summary Bullets:

  • 100 Gbps wavelength deployment appears to be picking up, a year later than expected.
  • A good deal of optical gear is using 25 Gigabaud modem techniques to achieve 100 Gbps.

I have been on the fence about 100 Gbps wavelengths for a while now.  Sure, the technology will become mainstream eventually.  However, 10 Gbps long-haul waves came through the door years ago and ramped up fast; they are cheap and plentiful on competitive routes.  Meanwhile, major U.S. service providers touted that they would add 100 Gigs commercially by late 2010, but well into 2011, the U.S. service providers as a whole had only confirmed operating a handful of 100 Gbps terrestrial routes internally.
