Compact CWDM devices also called CCWDM have advantages due to their small package size, low insertion loss, consistency, and good environmental stability. The multi-wavelength optical signal in the CCWDM device enters through the input fiber. It is mainly used in the MAN backbone layer, MAN convergence layer, and MAN access layer.
