已经在各种长度的单模光纤,直到31.6公里长度上进行了偏振稳定性试验。其中没有一个具有保持偏振特性设计。发现这些光纤的输出偏振态在整个96小时的试验期间改变很少。
Polarization stability tests have been conducted on single-mode fibers of various lengths up to a length of 31.6 km. None of them have a polarization maintaining design. The output polarization states of these fibers were found to change less during the entire 96 hour test period.
