Abstract :
A packet-selective reconfigurable optical add/drop multiplexer (ROADM) that combines an acousto-optic wavelength-tunable filter (AOTF) and an optical packet ADM (PADM) using optical code label processing has been proposed and demonstrated. It provides more efficient utilization of wavelengths than conventional ROADMs. In this paper, we report an overview of past achievements, which include the proposal, demonstrations, related key technologies, and the developed prototype of the packet-selective ROADM. A field trial of 640 Gbit/s, granularity-flexible optical network using the packet-selective ROADM prototype is successfully demonstrated in 16-channel WDM network.
