摘要： An optical switch according to the present invention includes a multiple-stage optical-switch unit that includes one input port (11) and a plurality of output ports (13) that are configured by connecting multiple stages of optical switching elements (10) each of which includes three or more optical input-output ports; and a switching control circuit (20) that, when receiving a switching instruction to switch an output destination of light input from the input port (11), executes at first a first control that changes setting of an optical switching element (10) that is included in part not overlapping with an optical transmission channel reaching an optical output port before switching in an optical transmission channel reaching an optical output port after switching and is positioned at a point other than a branch point from an overlapping part, and then executes a second control that changes setting of an optical switching element (10) that is positioned at the branch point.

摘要： An optical network system that performs transmission of N:1 protection includes a node (101) that includes transmission-side operating muxponders (3-1 to 3-N) that multiplex client signals for every M-channel signal bundle and convert multiplexed signals into optical signals having different wavelengths, transmission-side optical couplers (2-1 to 2-4N) that branch the client signals into two channels of operating and redundant, transmission-side optical switches (5-1 to 5-N) each selecting one channel from redundant signals as a redundant client signal, and a transmission-side redundant muxponder (6) that performs a predetermined transmission-side process according to an accommodation mode set on the redundant client signal and then multiplexes the redundant client signals, converts the multiplexed signal into an optical signal having a wavelength different from that of the operating signal, thereby making the accommodation mode settable for each channel in an independent manner.
