Wavelength Division Multiplexing
It details the two main standards: coarse WDM (CWDM), with few channels and wide spacing for applications like metropolitan networks, and dense WDM
WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM). Normal WDM (sometimes called BWDM) uses the two normal wavelengths 1310 and 1550 nm on one fiber. Coarse WDM provides up to 16 channels across multi...
