引言梯度光纤维与阶跃式光纤维相比较,其优点是:色散小、基带响应宽、通信容量大、光纤损耗也同样可以做到很低。制造工艺比阶跃光纤维复杂,比单模光纤维容易。它是当前光通信走向实用化的一种最有希望的光纤维。光纤维的结构参数决定着它本身的许多技术指标,对光纤维的传输特性影响很大,是光
INTRODUCTION Gradient optical fibers have the following advantages over step optical fibers: small dispersion, wide baseband response, large communication capacity, and low fiber loss. The manufacturing process is more complicated than the step optical fiber and easier than the single mode optical fiber. It is one of the most promising optical fibers in practical application of optical communications. The structural parameters of optical fiber determine many of its own technical indicators, the transmission characteristics of optical fiber has a great impact on the light
