Comment on Laser puts record data rate through fibre: 26 terabits per secondparentComments−oasisbob15yI was wondering the same thing, and tracked down the original article: http://www.nature.com/nphoton/journal/vaop/ncurrent/full/nph...There's a diagram available in the abstract that compares OFDM (the technique they use) with WDM.Apparently OFDM only uses a single light-source, versus (C|D)WDM, which multiplex multiple discrete wavelengths onto the same fiber.
