摘要
介绍了通过在多模光纤中引入周期性的扰动以改善多模光纤的传输特性.这种周期性的扰动是在光纤拉制过程中,通过相对于预制棒的光纤转动而实现的.对光纤进行的差分模式延迟(DMD)测试表明,扰动在一定程度上可以改善光纤中脉冲的分裂.
Abstract
In this paper, the transmitting characteristic of multimode fiber is improved by introducing the periodic scramble during the fiber′s drawing process. The scramble is some periodic and continuous left- or right-turning, so-called handness structure, by turning the fibers relative to the preform during the course of drawing process. The differential mode delay (DMD) test shows that this scrambling can reduce the split of optical pulse and improve the transmitting characteristic of multimode fiber.
