Network operators are moving towards next-generation Colorless, Directionless and Contentionless ROADMs (CDC-ROADMs) to increase the flexibility of their networks. Such so-called CDC-ROADMs require advances in optical component technologies, including high-port count Wavelength Selective Switches, Multicast Switches, Arrayed Amplifiers and Optical Channel Monitors. In this paper, we begin by examining the network-level requirements and see how these translate into component requirements and also identify opportunities to improve how these functional modules are integrated to optimize overall equipment design.
