摘要： A transmitting-end device generates a pilot signal with a pilot signal generation section, and transmits a pilot signal to a receiving-end device. At the receiving-end device, a transmission rate modification section detects the transmission band of an optical transmission line based on the amplitude of the pilot signal, and decides a data transmission rate acceptable to the receiving-end device by taking into account the transmission band of the optical transmission line. Based on a maximum data transmission data acceptable to the transmitting-end device and the data transmission rate thus decided, a control section in the receiving-end device arbitrates a data transmission rate between it and the transmitting-end device.

摘要： 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.

摘要： A detector outputs a detection signal indicating amplitude variation of an input frequency-multiplexed signal. An amplitude controller adjusts the amplitude of the frequency-multiplexed signal by referring to the detection signal. A modulator modulates the amplitude-adjusted frequency-multiplexed signal to produce a predetermined modulated signal. A second multiplexer multiplexes the modulated signal and the detection signal to produce a multiplexed signal. An optical transmitter converts the multiplexed signal into an optical signal, and then sends it out to an optical transmission path. An optical receiver converts the received optical signal into an electrical signal. A separator separates the modulated and detection signals from the electrical signal. A demodulator demodulates the modulated signal to output the frequency-multiplexed signal. An amplitude adjuster adjusts the amplitude of the frequency-multiplexed signal by referring to the detection signal to reproduce the original amplitude variation.

摘要： A wavelength-division multiplex optical transmission system is provided with: preliminary optical modulators 111 to 11n for outputting optical signals having different wavelengths from each other after being modulated by communications signals 11 to 1n that are signals to be supplied to specific optical receiving parts; an optical fiber 510 for transmitting the multiplexed optical signal; a subsequent optical modulator 210 for collectively modulating the transmitted optical signal so as to collectively modulate the optical signals being multiplexed by a broadcast signal 20 that is to be supplied equally to all optical receiving parts; and an optical fiber 520 for transmitting the modulated optical signal. A frequency band for the broadcast signal 20 is set not to overlap with any of those of the communications signals 11 to 1n. Accordingly, in each of optical receiving parts 411 to 41n, an electrical signal in which the communication signal 11 to 1n and the broadcast signal 20 are frequency-multiplexed can be obtained.

摘要： An angle modulating portion 1 converts an inputted electrical signal into a predetermined angle-modulated signal. An optical modulating portion 2 converts the angle-modulated signal outputted from the angle modulating portion 1 into an optical-modulated signal and sends the optical-modulated signal to an optical waveguide portion 3. An interference portion 6 separates the optical-modulated signal transmitted through the optical waveguide portion 3 into two optical signals having predetermined difference in propagation delay and then combines the optical signals. An optical/electrical converting portion 4 subjects the combined optical signal to homodyne detection, to acquire a demodulated signal of the original electrical signal and output the electrical signal. That is, the interference portion 6 and the optical/electrical converting portion 4 constitute a delayed detection system of an optical signal, so that the delayed detection system performs conversion processing of an optical signal into an electrical signal and angle demodulation processing simultaneously. In this way, a signal with a wide-band and a high-frequency can be acquired by demodulation without electrical part for wide-bands and high-frequencies.

摘要： An angle modulator branches a light emitted from a light source 101 into a first light and a second light. An optical intensity modulator 104 subjects the first light to predetermined optical intensity modulation with a first electrical signal having a predetermined frequency fc outputted from a first signal source 1031. An optical angle modulator 105 subjects the second light to optical angle modulation with a second electrical signal outputted from a second signal source 1032. An photo-detector 107 homodyne-detects an optical-intensity-modulated signal and an optical-angle-modulated signal that have been coupled by an optical coupler 106 using its square-law detection characteristics, and produces an angle-modulated signal having a center frequency fc as a beat signal. With the structure in which a wide-band angle-modulated signal is generated using the above optical signal processing, it is possible to achieve the angle modulator with suppressed noise independent of phase noise included in the light source.

摘要： An electrical signal to be frequency-modulated is branched into first and second signals. An FM laser 102 oscillates light having a wavelength .lambda.1 in a steady state condition, and outputs an optical signal obtained by converting an amplitude change in the inputted first signal into an optical intensity change and an optical frequency change. An optical detecting portion 106, to which the optical signal from the FM laser 102 and light having a wavelength .lambda.0 outputted from a local light source 104 are inputted, converts an optical intensity modulation component of the inputted optical signal as a current amplitude change by operating square-law detection characteristics, and generates a beat signal at a frequency corresponding to a difference in wavelength .DELTA..lambda. between the two inputted optical signals. A discrimination portion 110 discriminates using a threshold value generated on the basis of the second signal and converts the beat signal into the pulse signal. A high frequency component of the pulsed beat signal is removed by an LPF 311. Consequently, it is possible to generate an ideal wide band FM modulation signal by removing an amplitude variation and an average value variation from the beat signal generated by using an optical frequency modulating operation of a laser diode and heterodyne detection.
