英文摘要: In recent years, with the continued increasing of network users and emergence of new network business, the optical network faces huge challenge of data exchange and flexible bandwidth allocation . The traditional wavelength division multiplexing (WDM) optical networks based on ITUT-T with fixed data rate and inefficient network utilization can not adapt the future development of dynamic business. The bandwidth-variable optical networks supporting software defining can achieve high utilization of network resources by flexible software configuration and intelligent control, and it can provide flexible bandwidth allocation for highly dynamic business. In this project, we study the implementation of bandwidth-variable optical networks supporting software defining from physical level. We theoretically and experimentally study the key technologies of bandwidth-variable optical network nodes supporting software defining. We focus on software-defined bandwidth-variable transceiver technology, flexible optical switching technology and superchannel impairments monitoring technology.We aim to establish bandwidth-variable optical networks experimental platform supporting software defining and provide theoretical and technical support for next-generation optical switching networks.
