利用四波长双向光时域反射仪（OTDR）测量单模光纤沿着色散分布的无损测量技术与破坏性干涉技术进行了比较。实验结果与干涉测量结果吻合较好。此外，提出了一种测量程序，由不同类型的单模光纤组成的传输线。这些结果表明，该技术对于波分复用（WDM）和有限差分复用（FDM）光通信系统的设计是非常有用的。
A nondestructive measurement technique, which uses a four-wavelength bidirectional optical time domain reflectometer (OTDR) to measure the chromatic dispersion distribution along a single-mode fiber, is compared with the destructive interferometric technique. The experimental results obtained by this technique are in good agreement with those obtained by the interferometric technique. In addition, a measurement procedure is proposed for a transmission line composed of different types of single-mode fiber. These results show that this technique is extremely useful for the design of wavelength division multiplexer (WDM) and finite difference multiplexer (FDM) optical communication systems.
