Abstract:
The National Institute of Informatics (NII) has been conducting joint research with Japan-Telecom to develop a 40 Gbps optical transport system for the next-generation SuperSINET. We report on the recent results of field trials focused on automatic chromatic dispersion compensation and path protection/restoration applied to the future SuperSINET as key technologies required to maintain the quality of transmission, to reduce operational costs, and to facilitate the enhancement of network capabilities. From the results of the field trial, we have confirmed that an automatic optical path control system is essential in an all-optical wavelength path network.
