Abstract:
A method of optimizing an optical signal in an electro-optical switch array having a plurality of input and output ports including an optical output signal detection port and comprising a plurality of electro-optical switches responsive to control signals to selectively transmit optical signals among the access ports, the method comprising the steps of:applying an optical input signal to one of the input ports;selectively applying control signals of differing magnitudes to the switches;detecting optical output signals from the detection port and after application of each of the control signals;storing signal values representative of the detected optical output signals;defining a preferred signal value for optical output signals and comparing the stored signal values to the preferred value;selecting a control signal magnitude substantially equal to the magnitude of applied control signals resulting in optical output signal levels most nearly equal to the preferred value; and subsequently applying control signals of the selected magnitude.
