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： Modulators respectively modulate baseband signals into IF signals having different frequencies. A multiplexer multiplexes the IF signals. An electrical-optical converter intensity modulates the multiplexed IF signals into optical signals. A local oscillation signal source outputs a predetermined local oscillation signal. An external modulator intensity-modulates the optical signal using the local oscillation signal. An optical branching portion branches the intensity-modulated optical signal and respectively outputs branched optical signals to radio base stations. An optical-electrical converter converts the optical signal into an electric signal, to obtain an RF signal by frequency-converting the IF signal. An antenna only transmits a component having a desired radio frequency extracted in a band filter from the RF signal to a subscriber terminal. Frequency conversion from the IF signal to the RF signal is thus optically performed, whereby the frequency or electrical-optical converter is shared among the radio base stations.

摘要： An optical transmission apparatus capable of suppressing SBS by multiplexing an input signal with a pilot signal, and further capable of eliminating an adverse effect of intermodulation distortion between the input signal and the pilot signal is provided. When the input signal is a frequency-multiplexed signal obtained by multiplexing a plurality of signals aligned on a frequency axis at regular intervals &Dgr;f (&Dgr;f>0), a pilot signal generation part generates the pilot signal having a frequency {m−(1/2)}×&Dgr;f (m is an arbitrary natural number). A multiplex part multiplexes the input signal (electrical signal to be transmitted) with the pilot signal generated by the pilot signal generation part. An electrical-optical conversion part converts an electric signal outputted from the multiplex part into an optical signal through direct intensity modulation.

摘要： A data communication apparatus wherein stealthiness is enhanced by significantly increasing the time required for a wiretapper to decrypt an encrypted text. The data communication apparatus is constituted by connecting a data transmitting apparatus and a data receiving apparatus via a transmission path. The data transmitting apparatus receives a first predetermined initial value (key information) and information data, generates a multi-valued signal, the level of which varies substantially in a random number manner, and converts the multi-valued signal to a modulated signal of a predetermined modulation format for transmission. The data receiving apparatus demodulates the modulated signal to output the multi-valued signal, and then reproduces the information data from the multi-valued signal and a received second predetermined initial value (key information).

摘要： A data communication apparatus improves security against eavesdropping for secret communication by using Y-00 protocol. A multi-level code generation section generates, based on key information, a multi-level code sequence in which a signal level changes so as to be approximately random numbers. A level conversion section irreversibly converts the multi-level code sequence such that a converted multi-level code sequence does not constitute a mapping of the multi-level code sequence. A multi-level processing section generates a multi-level signal having a plurality of levels each corresponding to a combination between the information data and the multi-level code sequence. A modulator section modulates a multi-level signal in a predetermined modulation method and outputs a modulated signal.
