ABSTRACT
The article presents an economic analysis of major dense wavelength division multiplexing (DWDM) architectures that can be used to provide additional bandwidth. They include the Point-to-Point Mux/Demux DWDM, Fixed-OADM and Reconfigurable-OADM architectures. In fixed OADM DWDM architecture, only the specific channels destined for particular sites are selected and dropped. Reconfigurable-OADM has software-configurable wavelength add-drop functionality.
