Abstract

Optical fiber communication networks play an important role in the global telecommunication network. However, nonlinear effects in the optical fiber and transceiver noise greatly limit the performance of fiber communication systems. In this paper, the product of mutual information (MI) and communication bandwidth is used as the metric of the achievable information rate (AIR). The MI loss caused by the transceiver is also considered in this work, and the bit-wise MI, generalized mutual information (GMI), is used to calculate the AIR. This loss is more significant in the use of higher-order modulation formats. The AIR analysis is carried out in the QPSK, 16QAM, 64QAM and 256QAM modulation formats for the communication systems with different communication bandwidths and transmission distances based on the enhanced Gaussian noise (EGN) model. The paper provides suggestions for the selection of the optimal modulation format in different transmission scenarios.

c波段光纤通信系统可实现的信息速率优化。

光纤通信网络在全球电信网络中占有重要地位。然而，光纤中的非线性效应和收发器噪声极大地限制了光纤通信系统的性能。本文采用互信息(MI)与通信带宽的乘积作为可实现信息率(AIR)的度量。本文还考虑了由收发器引起的MI损失，并采用逐位MI，即广义互信息(GMI)来计算AIR。这种损耗在使用高阶调制格式时更为显著。基于增强高斯噪声(EGN)模型，对不同通信带宽和传输距离的通信系统分别在QPSK、16QAM、64QAM和256QAM调制格式下进行了AIR分析。本文对不同传输场景下调制格式的选择提出了建议。
