<P>PROBLEM TO BE SOLVED: To reduce the influence of transient response of the optical amplifier due to switching of an optical signal, and to enable high-speed switching in an optical cross-connect apparatus used in an optical network system including the optical amplifier. <P>SOLUTION: The optical cross-connect apparatus is provided on the optical network system for transmitting a wavelength multiplexed optical signal via an optical fiber transmission path and the optical amplifier, and switches the route of an optical signal of each wavelength of the wavelength multiplexed signal. This optical cross-connect apparatus is provided with a control means for controlling at least either the switching start timing of an optical signal of each wavelength or a time required for switching depending on the wavelength distance with an existing optical signal in switching for increasing/decreasing the optical signals of a plurality of wavelengths for the existing optical signal connected to a predetermined route. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
