The optical technical advancements currently provide the possibility for building the reconfigurable wavelength practical networks. These networks employ wavelength switching structures for dynamic routing of wavelengths and provide the level of flexibility and scalability that has not been already possible. Other components such as low-noise optical amplifiers, Electronic Dispersion Compensators (EDCs), advanced modulation techniques may more facilitate system operation and improve its capacity and accessibility. Developing new architectures for Optical Transport Networks (OTNs) and way of influence of these networks by vital parameters of system and state-of-art technologies regarding these components are examined. Reconfigurable Optical Add-Drop Multiplexers (ROADMs) are considered as key enablers for giving modern services in optical communications to support remote provision for optical routes and reconfiguration of topology of network. Based on various groups of properties and architectures of ROADMs, certain alternative relations may be purposed to designers of ROADM- based Dense Wavelength Division Multiplexing (DWDM) networks. In this essay, we deal with architectures and properties of various ROADMs.
