The existing switching modules for networking are lacked with some of the limitations associated with scalability, and configurability. Hence, this article introduces a more flexible, stack-based switching module, where some independent (1 × n) wavelength selective (WS) switches is realized on a single 4-degree network node. The stack-based WS switching module is designed in different ways such as either for transit side or add or drop operation of a Colourless, Directionless, and contentionless (CDC) ROADM (Re-configurable Optical Add or Drop Multiplexer). The ROADM design is introduced by applying stack-based WS switching scheme. The cost is analyzed through a 4-degree network node. The proposed CDC-ROADM architecture is demonstrated to recognize the cost reduction towards a minimum 35 percent in the proposed test network nodes when measured with the traditional/existing CDC-ROADM architecture based on multicasting switches and WS switches. According to experimental results, the proposed architecture can efficiently decrease the number of components in add or drop side and reduces the total cost of >70% and >80% in the proposed 4-degree network node.
