Coarse wavelength division multiplexing, the selected 20nm wavelength interval, abbreviated as CWDM, is mainly used in 2km data centers. We also know that the application of 100G optical modules in data centers is comparable to telecommunications applications, so the CWDM industry chain is very Mature, its wavelength selection has become a mainstream solution.
