我们用部署的40 Gb/S相干应答器监测了三条路径的偏振状态和偏振模色散，并进行了18个月的野外观测。在三条不同的路由中每条都监测了两条光纤路径，范围从30公里(一个放大跨度)到273公里(七个放大跨度)。总体而言，SOP和PMD变化缓慢，自相关半宽半极大值范围为1.3~4.1d，SOP为0.18~1.7d。我们观察到共享同一电缆的光纤路径之间的活动周期的相关性最大，而与共享办公室的光纤路径之间的相关性较弱。在18个月的时间里进行了超过10,000个小时的测量，我们相信这是关于掩埋光纤偏振行为的最广泛的研究。
We present 18 months of field observations on the state-of-polarization (SOP) and polarization-mode dispersion (PMD) on three routes monitored using deployed coherent 40 Gb/s transponders. Two fiber paths were monitored on each of three different routes, ranging from 30 km with one amplified span to 273 km with seven amplified spans. In general, the changes in SOP and PMD were slow, with the autocorrelation half-width-half-maxima ranging from 1.3 to 4.1 days for the differential-group-delay and from 0.18 to 1.7 days for the SOP. We observed the largest correlation of active periods between fiber paths sharing the same cable and weak correlation with fiber paths sharing an office. With over 10,000 hours of measurements spanning an 18-month period, we believe this to be the most extensive study published on the polarization behavior of buried fiber.
