The all-optical network (AON) demonstrator is a trial system-level testbed for the validation and verification of key network building blocks, scalable architectures, as well as control and management solutions for next-generation wavelength division multiplexing (WDM) networks. Developed at the Communications Research Centre (CRC) in Ottawa, ON, Canada, the AON testbed has already validated certain system-level concepts at the physical and upper layers. The paper describes the crucial role of the AON testbed in research, development, and "proof of concept" for both emerging optical technologies at the physical layer (performance characterization) and customer-managed networks at the upper layer (network management). Moreover, it is expected that the AON testbed will continue to be a valuable playground for future developments of emerging technologies, solutions, and applications.
