Patent number: 11979694Abstract: An optical and electronic integrated switch includes a network processor that controls the functions of the packet switch, a plurality of optical transceivers having photoelectric conversion functions, and a plurality of optical switches. The optical switches include different types of optical core switch and a plurality of optical-path selection switches. The optical transceivers provided near the processor have a regenerative relay function that regenerates optical signals and turns back the optical signals, and perform optical communication with a communication counterpart via the optical switches. In the optical communication, optical switches of the different types can cooperate to set paths for optical cut-through in which path selection is performed such that inputted optical signals are outputted without the intervention of the processor. This optical cut-through can be effectively performed without imposing a signal processing burden that consumes electric power on the processor.Type: GrantFiled: January 30, 2020Date of Patent: May 7, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Osamu Moriwaki, Shunichi Soma, Keita Yamaguchi, Kenya Suzuki, Seiki Kuwabara, Tetsuro Inui, Shuto Yamamoto, Seiji Okamoto, Hideki Nishizawa
