Abstract: An OADM in a wavelength division multiplexing transmission system includes a wavelength selection switch that selects a predetermined wavelength from a multiple optical signal obtained by multiplexing a phase modulated signal and an intensity modulated signal and outputs the selected wavelength signal to a predetermined output port. The wavelength selection switch has a different delay for each wavelength of the multiple optical signal. For example, the wavelength selection switch includes a mirror array. Optical paths from the surfaces of mirrors arranged on the mirror array to the diffraction grating are different in the case of adjacent mirrors.

Abstract: According to the WDM optical transmission system, for optical signals of respective wavelength in a WDM light propagated through a transmission path, a spectrum component at a center wavelength of each optical signal and a spectrum component in the vicinity of the center wavelength thereof are selectively attenuated by a spectrum correction optical filter, so that the WDM light is transmitted in a state where intensity of sideband components in the spectrum of each optical signal is relatively increased. As a result, even if spectrum width of the optical signal of each wavelength is limited when the WDM light passes through the band-limiting device on the transmission path, degradation of transmission characteristics caused by the attenuation of sideband components is reduced.

Abstract: When a network printer receives print data appended with related data from a client device via a network (S11), the related data is separated from the print data (S12) and stored in a predetermined region of a hard disk (S13). The print data is stored in the hard disk (S14) in correspondence with the related data. Then, printing is executed to print out the print data (S15). When a user requests display of the related data (S16:YES), the related data is displayed on a display (S17). The related data includes related image data and management data. When a user requests printing of the related data (S18:YES), a printer engine prints out the related data (S19). In this way, the user can select desired print data in a short period of time.
