Latest Patents
Tsuboi's latest patents include innovations such as an optical access network, a remote unit, an optical communication method, and an optical communication program. The optical access network he developed allows a remote unit to receive an optical burst signal. In this system, a central unit (OLT) transmits a DC-balanced optical continuous signal that includes packets with identification information for each remote unit (ONU). The optical switching module (OSM) then receives this signal, switches the packets based on their identification, and transmits a DC-balanced optical burst signal to the remote unit. Additionally, his optical switching device eliminates the need for a 2×1 optical splitter, thereby extending the transmission distance between the OLT and the ONU.
