A Programmable ROADM System for SDM/WDM Networks

This paper proposed and evaluated a programmable ROADM system for MCF-based SDM/WDM networks. The employing both bypass connection Route-and-Select wavelength switching enables adaptable virtual topology in optical networks by dynamically configuring cores. simulation results confirmed this could provide acceptable performance with an around 10–20% reduction the total cost including number of ports WSSs comparing fully flexible system, which cannot be implemented due to required extremely high-port-count WSSs.
