<P>PROBLEM TO BE SOLVED: To lower house-side power consumption and also to reduce costs while preventing an optical waveform from deteriorating. <P>SOLUTION: An optical transmission system 1 is an optical transmission system that transmits a down optical signal, sent from an office-side transceiver 2 to a house-side transceiver 3, and an up optical signal, sent from the house-side transceiver 3 to the station-side transceiver 2 and having a different wavelength from the down optical signal, using a multimode optical fiber 4. The station-side tranceiver 2 includes an equalizer 20 wherein a tap coefficient for correcting the signal waveform of the up signal from the house-side tranceiver 3 is set and an equalizer 16 wherein a tap coefficient for correcting the down signal is set, the tap coefficient of the equalizer 16 being set corresponding to the tap coefficient of the equalizer 20. <P>COPYRIGHT: (C)2009,JPO&INPIT |
