讨论了用1.55微米可调谐外腔激光二极管在80 nm带宽上用1.55微米相移技术测量80.6公里长的级联色散位移单模光纤的色散。结果表明，该方法不需要复杂的曲线拟合方程，也不需要大量指定波长的激光光源。因此，测量配置和程序相对简单。该技术可用于测量未来先进光纤的色散，例如具有不同折射率分布的色散平坦光纤。
Measurement of the chromatic dispersion of an 80.6-km-long, concatenated, dispersion-shifted, single-mode fiber (DSF) with a tunable 1.55- mu m external-cavity laser diode, using the phase-shift technique at 1.55 mu m over 80-nm bandwidth, is discussed. It is shown that the technique does not need intricate curve-fitting equations or a large number of laser sources with specified wavelengths. As a result, the measurement configuration and procedure are relatively simple. The technique is useful for measuring the chromatic dispersion of future advanced fibers such as dispersion flattened fibers with various refractive index profiles.<<ETX>>
