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： A method of manufacturing of power transmission chain 1 by interconnecting plural link plates 2 with pins 3. Individual pin pairs 3 are arranged and temporarily fixed to places. The link plates 2 are sequentially stacked in layers by press-fitting respective through-holes 4 of the link plates 2 about the respective pin pairs 3, whereby the link plates 2 are interconnected to form a circular chain (an endless loop). Subsequently, the individual pin pairs 3 are released from the temporarily fixed state. Thus, the manufacture of the power transmission chain 1 is decreased in the number of operation steps, so that the chain may be assembled easily.

A multi-level code generation section 111a generates, based on predetermined key information 11, a multi-level code sequence 12 in which a signal level changes so as to be approximately random numbers.

摘要： A first optical modulator converts an electrical signal into an optical-frequency-modulated signal, supplying the same with unmodulated light from a local light source to a first optical receiver. The first optical receiver generates an FM signal, which is a beat signal between the received two lights. This, FM signal is supplied to a filter, where only the carrier component thereof is extracted, and the carrier component is converted in frequency in the frequency converter. With the resultant signal after frequency conversion, a second optical modulator optically modulates the amplitude or intensity of the unmodulated light from the local light source. A second optical receiver receives the resultant signal after optical modulation and an optical signal from the first optical modulator, producing an FM signal, which is a beat signal between the received two optical signals. With such configuration, it is possible to realize high-frequency, wide-band frequency modulation, and also to suppress the phase noise included in the FM signal.

摘要： In an optical transmission system, a multiplexer frequency-division-multiplexes a plurality of signals, and outputs the resultant signal to an FM modularor. The FM modulator converts the frequency-division-multiplexed signal into an FM modulated signal through frequency modulation using the frequency-division-multiplexed signal as an original signal. A frequency-divider converts the FM modulated signal into a frequency-divided FM modulated signal whose frequency is ½n (n is an integer of not less than 1) the frequency of the FM modulated signal. An optical modulator has a predetermined input-voltage vs. output-optical-power characteristic, and is biased at the minimum point (voltage) about the output optical power. The optical modulator modulates an unmodulated light fed from a light source with the applied frequency-divided FM modulated signal to produce an optical signal whose optical carrier component is suppressed, and sends the optical signal to an optical transmission line. An optical receiver receives the optical signal, and square-law detects the signal to convert into an FM modulated signal. A FM demodulator demodulates the FM modulated signal to reproduce the original frequency-division-multiplexed signal. This configuration makes it possible to narrow the bandwidth of an FM modulated signal while increasing the frequency deviation thereof, and realize high-quality signal transmission as a result.
