摘要： PROBLEM TO BE SOLVED: To provide an optical path cross connection apparatus having a route change function on a large-scale at a remarkable low price.SOLUTION: For routing a wavelength group or a wavelength included in wavelength division multiplex light from the optical input fibers Fi1 to FiN to any one of optical input fibers Fo1 to FoN, an optical path cross connection apparatus includes: a plurality of 1×D wavelength selection switches WSS that are provided at each of optical input fibers Fi1 to FiN and selectively output a wavelength to any output port in output ports of the number of D by corresponding to a wavelength of each of the optical input fibers Fi1 to FiN; and 1×n wavelength group selection switches WBSS that are provided at each of the output ports of the number of D and selectively output a wavelength group to any optical output fiber in optical output fibers of the number of n by corresponding to a wavelength group outputted from each of the output ports. Thus, since the optical path cross connection apparatus uses a two-stage structure composed of the wavelength selection switch and the wavelength group selection switch, the number of output ports in the wavelength selection switch WSS is greatly reduced to 1/n.

摘要： PROBLEM TO BE SOLVED: To meet the need for a new configuration of an optical variable filter, which allows further reduction in scale of switches to cope with the increase in the number of element optical switches due to the increase in the number of wavelength paths to be processed by the optical variable filter, in consideration that technical developments of wavelength division multiplex technology and respective optical devices are expected because of rapidly increasing network traffic and in anticipation that the number of wavelengths included in wavelength division multiplexed light in one optical fiber transmission line will exceed a maximum of 200 in the near future.SOLUTION: An optical variable filter is constituted by utilizing a selection function of input ports of a cyclic AWG and utilizing compact, low-cost, and high-reliability devices. A configuration is implemented where proper setting of an FSR of the cyclic AWG and selection of input/output ports are performed and a condition for the number of wavelengths to be demultiplexed is determined to reduce the scale of an optical switch. In the optical variable filter, the more increased the number of wavelength paths is, the more effectively reduced the number of element optical switches is.

摘要： PROBLEM TO BE SOLVED: To improve resource utilization efficiency in an optical network that allocates resources to paths by using frequency slots.SOLUTION: In an optical network comprising link-connected variable bandwidth communication device groups, when a network control device determines that there is no route having a free frequency slot to be allocated to a required path, the control device performs a path relocation process.
