摘要： A method for producing low-PMD fiber, in which a glass fiber is drawn from an optical fiber perform by a tractor which pulls such optical fiber from said perform; subsequent to said tractor pulling the fiber is twisted about its axis to increase the magnitude of twist which is imparted to said fiber. The fiber is then wound onto a fiber storage spool such that at least a portion of the twist imparted to said optical fiber is retained while said fiber is wound on said spool.

摘要： A method for screening fiber polarization mode dispersion using a polarization optical time domain reflectometer. A pulse radiation is emitted into the fiber under test, and the backscattered radiation is measured by the POTDR and used to obtain a POTDR trace. The POTDR trace is then analyzed to compare the variation of signals along the length of the fiber, the variation in signals relating to the level of PMD along the length of the fiber. Because high levels of PMD correspond to localized levels of low variability, by setting the variability of signal threshold sufficiently low, fibers having unacceptably high localized PMD can be identified and removed.
摘要翻译：一种使用偏振光学时域反射计屏蔽光纤偏振模色散的方法。脉冲辐射被发射到被测光纤中，反向散射辐射由POTDR测量并用于获得POTDR迹线。然后分析POTDR迹线以比较沿着光纤长度的信号的变化，与沿着光纤长度的PMD的水平相关的信号的变化。由于高水平的PMD对应于低变异性的局部水平，通过将信号阈值的可变性设置得足够低，可以识别和去除具有不可接受的高局部PMD的纤维。

摘要： A method for determining a position of a selected area of a sheet of material relative to a reference plane includes launching a first incident light beam at the selected area of the sheet of material such that the first incident light beam strikes the selected area at a first position and a first angle, thereby producing a first reflected light beam. A second incident light beam is launched at the selected area of the sheet of material such that the second incident light beam strikes the selected area at a second position and a second angle, thereby producing a second reflected light beam. The second position and second angle are different from the first position and first angle, respectively. The first reflected light beam and the second reflected light beam are intercepted at the reference plane. Information related to positions at which the reflected light beams were intercepted and angles at which the incident light beams were launched were received and correlated to the position of the selected area relative to the reference plane.
