This report is the first demonstration of RoF-DAS over WDM-PON with TDM techniques to realize a broadband ubiquitous wireless access with a gigabit-class throughput. The optical transmission performance of RF signals is evaluated through experiments.
This paper discusses an upstream emergency optical access system that allows voice communication during power failure, and describes the ADC bit resolution requirements. Then we report the adequacy of previously reported up-conversion frequency based on this discussion.
This paper proposes an optical access system that enables voice communication services to continue when a power failure occurs. In particular, we propose applying a digital signal processing technique namely blind speech separation (BSS) to an optical multiple access system for demultiplexing randomly mixture signals received from an upstream user. We present a brief overview and the target of proposed...
