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.

The most important advantage of CWDM is low equipment cost. Due to the wide wavelength interval of the CWDM system and the low technical requirements of the laser, the structure of the laser is greatly simplified and the yield is improved. In addition, the power consumption and physical size of the CWDM (R) system are much smaller than those of the DWDM system.
