摘要： The present invention provides a node apparatus, where two N x N wavelength selective switches are used to form a parallel-connected structure, and two ends of each power splitter are separately connected to input ends of the N x N wavelength selective switches, and two ends of each power combiner are separately connected to output ends of the N x N wavelength selective switches, thereby transferring route switching selection work originally performed between multiple 1 x M wavelength selective switches to the inside of the N x N wavelength selective switch for implementation. Compared with an original structure using discrete components, the node apparatus is simplified, and when a traffic volume expands, the number of module slots on a line side does not need to be increased, thereby reducing usage costs eventually. The present invention is used for signal transmission in a node.
