Patent number: 10250348Abstract: In the optical transport system a transport frame generator divides a transport frame accommodating plural client signals into plural transmission signals. Subcarrier transmission units convert the signals into optical signals using different optical carriers and transmit the converted optical signals. Subcarrier reception units receive the transmitted optical signals and convert the optical signals into reception signals. A transport frame termination unit combines the reception signals to restore the transport frame. A time-demultiplexing processor time-demultiplexes the restored transport frame to be separated into the client signals. A time slot control unit determines a new time slot allocation when time-multiplexing the client signals in the transport frame and stops supply of electric power to a subcarrier transmission unit and a subcarrier reception unit that transmit and receive an optical signal to which the client signals are not allocated.Type: GrantFiled: November 26, 2015Date of Patent: April 2, 2019Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yoshiaki Yamada, Kengo Shintaku, Takuya Ohara, Kei Kitamura, Takashi Kotanigawa, Takafumi Hamano, Kaoru Arai, Masahiro Yokota, Hideki Maeda

Patent number: 10230457Abstract: A framer in a transmission device allocates plural optical channel time slots to a plurality of logical prioritized paths. It allocates received client signals to the allocated time slots, and transmits the client signals by a plurality of optical subcarriers that use a plurality of optical wavelengths corresponding to the plurality of time slots. The framer includes: a time slot allocation unit that, in a case where an optical wavelength corresponding to a time slot allocated to a logical path having a high transmission priority is not used, allocates at least one of the plurality of time slots to the logical path having the high transmission priority while the time slot corresponding to the unused optical wavelength is avoided, to change the time slot allocated to the logical path having the high transmission priority.Type: GrantFiled: November 27, 2015Date of Patent: March 12, 2019Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Kei Kitamura, Takafumi Hamano, Takashi Kotanigawa, Kaoru Arai, Masahiro Yokota, Hideki Maeda, Yoshiaki Yamada, Takuya Ohara, Kengo Shintaku
