Can someone "compare and contrast" this with existing CWDM and DWDM technologies, which also use different "colors" (think different frequencies, really) travel

Can someone "compare and contrast" this with existing CWDM and DWDM technologies, which also use different "colors" (think different frequencies, really) traveling over the same fiber?
- oasisbob 15y agoI was wondering the same thing, and tracked down the original article: http://www.nature.com/nphoton/journal/vaop/ncurrent/full/nphoton.2011.74.html 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.
