“…Optical Add/Drop Multiplexers (ROADMs) are devices that enable very efficient provision of WDM services across different optical networks and extensive research has been undertaken to explore the flexibility and cost effectiveness of ROADMs [4], [5], [6], [7], [8], [9], [10]. This is because ROADMs can be employed to remotely reconfigure and add and drop wavelengths, which simplify network upgrades and minimizes operational costs.…”

In order to evaluate the performance of Reconfigurable Optical Add/Drop Multiplexers (ROADMs) consisting of a single large switch, in circuit switched Wavelength-Division Multiplexing (WDM) networks, a theoretical Queuing Network Model (QNM) is developed, which consists of two M/M/c/c loss systems each of which is analyzed in isolation. An overall analytical blocking probability of a ROADM is obtained. This model can also be used for the performance optimization of ROADMs with a single switch capable of switching all or a partial number of the wavelengths being used. It is demonstrated how the proposed model can be used for the performance evaluation of a ROADM for different number of wavelengths inside the switch, in various traffic intensity conditions producing an exact blocking probability solution. The accuracy of the analytical results is validated by simulation.

“…In this paper, we focus on the semi-filterless approach using wavelength blockers (WB) inside the nodes. While WB-based reconfigurable optical ring nodes architectures are not new [7], they have recently regained attention in conjunction with coherent transponder technology. The WB devices considered here are based on liquid-crystal-on-silicon (LCoS) technology, similar to [8].…”
