WDM technologies are applied to the long-distance communication network. Cost effectiveness is more important for applying this WDM technologies to communication network in small area. Optical receiver which is provided with optical BPF is newly designed in order to choose one wavelength out of multiple input wavelengths. Besides, in order to make compensation for the transmission loss in transmission pass, erbium-doped fiber amplifier is developed. In the previous paper, simplified WDM system was proposed using newly designed this optical receiver and this compact EDFA. In this paper, we tried to improve EDFA and evaluated it. By using this EDFA in the point-to-point system, power budget is improved by 3.9 dB. By utilizing the high gain characteristic possibility of constructing 16〜32WDM system is shown.
