      CWDM

      Coarse Wavelength Multiplexing (CWDM) is a wavelength multiplexing technology for city and access networks. Transmission is realized using 16 channels with wavelengths between 1270 nm and 1610 nm. Due to the channel spacing of 20 nm cost-effective lasers can be used. The channel width itself is 13 nm. The remaining 7 nm is designed to secure the space to the next channel.

      DWDM

      The functionality of DWDM resembles to the one of CWDM. Unlike to CWDM technology, the channel spacing for DWDM is 0.8/0.4 nm (100 GHz/50 GHz grid). This small channel spacing allows to transmit simultaneously much more information. Currently a restriction on wavelengths between 1530 nm and 1625 nm exists which corresponds to the C and L band. In this connection DWDM wavelengths from DWDM technology is more expensive compared to CWDM caused by the need of more sophisticated transceivers.
