Coarse Wavelengh Division Multiplexer
Thin Film Filter Based CWDM
3A Coarse wave-division multiplexing (CWDM) is an implementation of WDM technology for short-to-medium-haul networks. CWDM and DWDM differ in the spacing between adjacent wavelengths. Epoxy-free in optical paths for greater reliability using proprietary packaging techniques. 3A CWDM thus can be used in high power applications.
