    • An optical brancher 110 branches an input optical signal into two. An optical detector 120 converts one optical signal branched by t e optical brancher 110 into an electrical signal. A first controller 122 generates a control electrical signal having a waveform obtained by inverting the envelope of the electrical signal. Based on the control electrical signal, an optical signal generator 124 produces a dummy optical signal having a waveform &lgr;d and an amplitude &agr;/2. The other signal branched by the optical brancher 110 is delayed by a delay unit 112 for a predetermined time, and then multiplexed by an optical multiplexer 114 with the dummy optical signal from the optical signal generator 124. An optical amplifier 116 amplifies a multiplexed optical signal. An optical filter 118 separates an optical signal of a wavelength &lgr;1 from the amplified optical signal. Thus optical signal amplification can be carried out without optical surges.

    • A data unit 1010 outputs an information signal to be transmitted in the form of optical packets, as well as wavelength information representing a wavelength of each optical packet. A first modulating signal processing unit 1051 receives an information signal, and inserts an electric signal (“dummy signal”) in any no-data period during which the information signal is absent, and outputs the resultant signal as a modulating signal. The dummy signal has the same amplitude as that of the information signal. A wavelength information processing unit 1021 outputs a wavelength controlling current corresponding to the wavelength information, and in any no-data period, outputs a wavelength controlling current corresponding to a wavelength which is different from the wavelengths represented by the wavelength information. A wavelength-tunable light source 1030 outputs light of a wavelength corresponding to the wavelength controlling current. An optical modulation unit 1040 modulates the light outputted from the wavelength-tunable light source 1030 with the modulating signal, and outputs the modulated signal as optical packets. As a result, an optical surge is prevented from occurring at the time of amplifying intermittently generated optical packets.
