摘要： A first transmitting section frequency-multiplexes a data signal and a monitor signal, and then converts the resultant signal to an optical signal for output. A first receiving section converts the optical signal transmitted via a first optical transmission path and a wavelength demultiplexer into an electrical signal, and then extracts the monitor signal. A difference detector compares a monitor signal level with a predetermined reference level, and then outputs wavelength information to a second optical transmission path. Based on the wavelength information transmitted via the second optical transmission path, a first wavelength controller adjusts the wavelength of the optical signal for stabilization at a predetermined wavelength. Thus, it is possible to achieve a wavelength division multiplex transmission system capable of controlling the wavelength of the optical signal at low cost.

摘要： The present invention provides a low-cost optical transmission system using a plurality of subscriber lines which is capable of efficiently utilizing an optical transmission path. A communication status observing section 116 in a transmitting device 1 classifies subscribers into a plurality of groups based on a communication status at each subscriber end, and outputs constellation level information and level information which are different for each group. For each constant cycle, a modulation control section 117 and a gain control section 118 respectively set a QAM constellation level and a signal level which are different for each group and used in a basic modulating section 103.

摘要： In a transmitter (11), a peak detection section (104) detects a peak factor of a frequency division multiplexed signal which is output from a frequency division multiplex section (103). A spurious calculation section (105) instructs a gain adjustment section (106) to adjust the signal level of the frequency division multiplexed signal so that the level of spurious components (e.g., adjacent channel leakage power ratio (ACLR)) is equal to or less than a predetermined level, based on the peak factor.
