Abstract:
1. An optical communication apparatus comprising: an optical modulating unit modulating input light entered to an input port in accordance with a modulation signal to be transmitted, to thereby output a modulated optical signal; an optical branching unit branching the modulated optical signal into first and second branched optical signals, and outputting the first branched optical signal to an output port; an operating point controlling unit controlling said optical modulating unit in accordance with the second branched optical signal; a modulation signal detecting unit detecting a signal intensity of said modulation signal; and a controlling unit maintaining an operating point of said operating point controlling unit when the detected signal intensity is equal to or lower than a predetermined value, and controlling an operation of said operating point controlling unit from a maintained operating point when the detected signal intensity becomes higher than the predetermined value from a value equal to or lower than the predetermined value.
