这糊礼品并且来临为 VSR-1 光连接计算分散惩罚。基于一个特定的 VSR-1 连接的参数,分散惩罚分别地为各种各样的形式的分散带宽被计算。最坏的眼睛闭合被在时间 0 点使用信号波形数字地表示,并且信号波形通过快速傅里叶变换算法在频率领域被获得。由这条途径,分散惩罚被各种各样的部件的转移功能的形状在连接决定。为了简化 multimode 纤维连接转移的推导,工作,规范的推动反应的一种 Gaussian 形式被使用。这条计算途径能被用来在连接预算分析估计 VSR-1 连接的最坏的分散惩罚。CLC 数字 TN929。11 文件代码 A 由鈥 ? 支持了 63 鈥 ? 高技术研究和开发节目(2005AA311030 ) 和中国(资助号码 60502005 ) 的国家自然科学基础
This paper presents an approach to calculate dispersion penalty for VSR-1 optical links. Based on parameters of a specific VSR-1 link, dispersion penalties are computed for various modal dispersion bandwidths respectively. The worst-case eye closure is expressed numerically by using the signal waveform at time 0, and the signal waveform is obtained in frequency domain through FFT algorithm. By this approach,the dispersion penalty is determined by the shape of transfer functions of the various components in the links. To simplify the derivation of multimode fiber link transfer function,a Gaussian form of normalized impulse response is used. This calculation approach can be used to estimate the worst-case dispersion penalty of VSR-1 links in the link budget analysis.
