ROADM Enabled Optimization in WDM Rings

Tags: network management, capital, network, management

Overview Dense Wavelength Division Multiplexing (DWDM) has established itself as the cheapest and most reliable mechanism for transporting information bits in long haul as well as in regional metro networks. For reasons of resiliency and simplicity, DWDM networks are predominantly configured as rings, consisting of fiber links connecting Optical Add-Drop Multiplexers (OADM). In past few years Reconfigurable OADM (ROADM) architectures have been proposed in order to automate network management and allow the transport network to adapt more readily to changing loads. This paper makes a case that ROADM deployment not only reduces operating expenditure but the added flexibility helps save/defer capital investment.
