    • According to the WDM optical transmission system, for optical signals of respective wavelength in a WDM light propagated through a transmission path, a spectrum component at a center wavelength of each optical signal and a spectrum component in the vicinity of the center wavelength thereof are selectively attenuated by a spectrum correction optical filter, so that the WDM light is transmitted in a state where intensity of sideband components in the spectrum of each optical signal is relatively increased. As a result, even if spectrum width of the optical signal of each wavelength is limited when the WDM light passes through the band-limiting device on the transmission path, degradation of transmission characteristics caused by the attenuation of sideband components is reduced.
    • 根据WDM光传输系统,对于通过传输路径传播的WDM光中的相应波长的光信号,每个光信号的中心波长的光谱分量和其中心波长附近的光谱分量被选择性地衰减 通过光谱校正滤光器,使得WDM光在每个光信号的光谱中的边带分量的强度相对增加的状态下传输。 结果,即使当WDM光通过传输路径上的带限设备时,即使每个波长的光信号的光谱宽度受到限制,也减少了由边带分量的衰减引起的传输特性的劣化。
