Abstract:
1. An optical exchange for a wavelength division multiplexed (WDM) optical network, comprising: (a) a plurality of input ports from which a plurality of optical signals are to be inputted; (b) a plurality of output ports to be allocated one to each of said input ports; (c) deflecting means for deflecting the optical signals, which are inputted via said input ports, and outputting the deflected optical signals to said output ports; (d) storing means for storing deflection information about a plurality of target amounts of deflection to which the respective input optical signals are to be individually deflected by said deflecting means, one target amount for each of said output ports, which are to be allocated to the respective input ports; and (e) controlling/driving means for controlling/driving said deflecting means so as to set amounts of deflection of the individual input optical signals based on the deflection information stored in said storing means; said controlling/driving means including
