Coupling between these polarization modes can be provided by acoustic torsional waves propagating along the fiber.

通过在沿光纤方向加入声扭波可以引起两个偏振模发生耦合。

The fiber is internally reflective at specific points, so that when light is sent along the fiber, some of it bounces back to a detector.

在特定点上，纤维可以向内反射光线，当光线沿纤维传输时，部分会反射到探测器上。

This solution can quickly calculate the laser and pump power distribution along the fiber and the output power. The result of the percentage error is about 1% and up to 0.2%.

这种解法能够迅速计算出激光及抽运光沿光纤的功率分布状况以及输出功率，计算误差百分比约为1%，最高达到0.2%；

Some trading firms measure their competitiveness by the speed in which they can connect to financial exchanges and complete transactions, and even at the speed of light that data travels along the glass of fiber optic lines, locating even a few miles closer to the exchange could provide an edge.

The production model is a polished-looking assemblage of aluminum and judiciously placed titanium and carbon fiber, along with sensors, motors, joints, off-the-shelf DSPs and custom circuitry and software.
