与模式相关的损耗和增益:统计数据及其对模分复用的影响

Mode-Dependent Loss and Gain: Statistics and Effect on Mode-Division Multiplexing

Keang-Po Ho, Joseph M. Kahn

摘要:

在多模光纤传输系统中,模式相关的损耗和增益(统称为MDL)造成了基本的性能限制。在强模式耦合的制度中,MDL的统计数据(以分贝或对数功率增益单位表示)可以通过小MDL区域中的零迹高斯酉系综的本征值分布来描述,该小MDL区域预期对实际长距离传输感兴趣。研究了在MDL存在的情况下,模分复用系统的信息论信道容量,包括有和没有信道状态信息时的平均容量和中断容量。

英文摘要:

In multimode fiber transmission systems, mode-dependent loss and gain (collectively referred to as MDL) pose fundamental performance limitations. In the regime of strong mode coupling, the statistics of MDL (expressed in decibels or log power gain units) can be described by the eigenvalue distribution of zero-trace Gaussian unitary ensemble in the small-MDL region that is expected to be of interest for practical long-haul transmission. Information-theoretic channel capacities of mode-division-multiplexed systems in the presence of MDL are studied, including average and outage capacities, with and without channel state information.
