摘要

本文比较了单模光纤(SMF)和非零色散位移光纤(NZ-DSF)的非线性效应对光相干传输系统性能的影响。利用增强高斯噪声(EGN)模型估计光纤的非线性效应，即非线性干涉噪声(NLIN)，并考虑非线性干涉噪声和光放大器噪声(ASE)噪声，计算光相干传输系统的信噪比(SNR)。通过考虑EGN模型，对考虑SMF和NZ-DSF的光学相干系统的午餐功率进行了优化。最后，对100Gbps光相干传输系统进行了仿真，并与基于EGN模型的分析结果进行了比较。分析结果与仿真结果的接近表明了EGN模型和功率优化公式的准确性。

Comparing Nonlinearity Effects of SMF and NZ-DSF fibers on the Performance of Optical Coherent Transmission Systems

In this paper, we compare the nonlinearity effects of single mode fiber (SMF) and non-zero dispersion shifted fiber (NZ-DSF) on the performance of optical coherent transmission systems. We estimate the nonlinearity effects of fiber, referred to as nonlinear interference noise (NLIN), by using the so-called enhanced Gaussian noise (EGN) model, and compute signal to noise ration (SNR) of optical coherent transmission system by considering NLIN and optical amplifier noise, referred to as amplified spontaneous emission (ASE) noise. By considering EGN model we optimize the lunch power of optical coherent systems considering SMF and NZ-DSF. Finally, a 100Gbps optical coherent transmission system is simulated and its results are compared with analytical results obtained based on the EGN model. The closeness between analytical and simulation results reveal the accuracy of the EGN model and the power optimization formulations.
