WebCWDM has nearly 100 times wider channel spacing needed for frequency stability. This means that CWDM supports fewer channels than DWDM, accommodating up to 18 channels. However, the optical interface components CWDM uses do not have to be as precise as DWDM components. WebWDM wavelengths are positioned in a grid having exactly 100 GHz (about 0.8 nm) spacing in optical frequency, with a reference frequency fixed at 193.10 THz (1,552.52 nm). [8] …
