  • Patent number: 11979226
    Abstract: 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.

  • Publication number: 20240078174
    Abstract: An information storage device includes a storage unit, a control unit, an allocation information storage unit, a QoS parameter storage unit, and a monitoring result storage unit. The control unit creates and manages a logical storage area using the storage area of the storage unit when a storage area allocation request is received. The allocation information storage unit stores allocation information related to logical storage areas. The QoS parameter storage unit stores quality requests expected to be satisfied for a communication for using the logical storage area. The control unit monitors the operating state and characteristics of the storage unit and the communication status, and stores the results in the monitoring result storage unit. The control unit derives internal QoS parameters to be set in the information storage device from the information stored in the allocation information storage unit, the QoS parameter storage unit, and the monitoring result storage unit.
