Patent number: 11979226Abstract: A wavelength cross-connect device performs relay processing, the relay processing being such that wavelength multiplexed signal lights, which are multiband transmitted from a plurality of routes, are demultiplexed into different wavelength bands, and for each route, respective optical signals of the different wavelength bands are amplified, then subject to route change by WSSs and outputted to output side routes M. The device includes C-band WXC units that are the same in total number as the wavelength bands of the optical signals of the respective wavelength bands and perform relay processing on optical signals of a specific wavelength band of the different wavelength bands.Type: GrantFiled: February 4, 2020Date of Patent: May 7, 2024Assignee: Nippon Telegraph and Telephone CorporationInventors: Hiroki Kawahara, Takeshi Seki, Sachio Suda, Kohei Saito, Kenta Hirose
