在干线网络和接入网中安装了许多1.3-/spl mu/m SM （zero-dispersion single-mode）光纤。近年来，人们对波分复用（wavelength-division multiplexing， WDM）系统进行了大量研究，以提高传输容量和灵活性。如果我们可以使用SM光纤电缆网络构建WDM系统，设计使用1.3-/spl mu/m窗口（o波段）的波长进行传输，这将证明在降低建设成本方面非常有效。因此，重要的是检查已经安装并连接了几根光纤的SM光纤电缆和网络的传输特性对波长的依赖性。在本文中，我们描述了测量的SM光纤电缆的光特性和安装的光纤光缆网络在不同的波长。在1.46 ~ 1.625-/spl mu/m波长范围内光纤特性稳定，表明所安装的SM光缆网络可用于WDM系统。
Many cables containing 1.3-/spl mu/m zero-dispersion single-mode (SM) optical fibers are installed in trunk and access networks. Recently, there have been a number of studies on wavelength-division-multiplexing (WDM) systems designed to increase transmission capacity and flexibility. If we can construct WDM systems using SM optical-fiber cable networks designed to transmit using wavelengths in the 1.3-/spl mu/m window (O-band), this will prove very effective in reducing construction costs. It is therefore important to examine the wavelength dependence of the transmission characteristics of SM optical-fiber cables and networks that have already been installed and in which several optical fibers are joined. In this paper, we describe the measured optical characteristics of SM optical-fiber cables and installed optical-fiber cable networks at various wavelengths. The optical characteristics were stable in the 1.46 to 1.625-/spl mu/m wavelength range and we confirmed that the installed SM optical-fiber cable networks could be used for WDM system applications.
