CWDM / DWDM integration – an easy-to-realize expansion of existing CWDM systems
 

The difference between CWDM and DWDM lies in the channel spacing between neighbored wavelengths, for CWDM 20 nm and for DWDM 0.8/0.4 nm (using 100 GHz/50 GHz grid). Pan Dacom Direkt utilizes this advantage for an efficient CWDM/DWDM integration. Thereby up to sixteen DWDM channels are transmitted simultaneously in only one CWDM channel (1530 nm and 1550 nm). Thus an easy-to-realize channel extension can be achieved under continued use of existing CWDM components and thereby garantuees a protection of investment.
