摘要

【目的】

由于数据中心网络的高速发展，对高速率、大容量数据中心光传输系统的性能研究也极为迫切，单载波400或600 Gbit/s传输将逐渐成为下一代通信网络主流的传输速率，当前人们对400 Gbit/s传输系统在数据中心网络中应用的研究较为广泛，而对600 Gbit/s传输系统的详细研究较少。

【方法】

为了满足数据中心通信容量日益增长的需求，文章基于单载波600 Gbit/s速率下一代数据中心弹性光网络（EON）传输系统，对影响传输系统的传输距离和频谱利用效率问题进行了详细的理论分析和实验研究。

【结果】

分析表明，单载波最大入纤光功率决定传输系统的最大传输距离，而传输系统的频谱利用效率与传输通道带宽有关，同时对单载波600 Gbit/s EON传输系统进行实验研究，实验通过对比不同入纤光功率与系统

因子和纠前误码率的关系，以及不同通道数3 dB通道滤波带宽与系统

因子的关系，证实系统传输距离和频谱利用效率分别与最佳入纤光功率和滤波带宽有关，并且实验表明，600 Gbit/s传输系统最佳单波入纤光功率和最佳滤波带宽分别为＋4 dBm和77 GHz，此时系统传输距离最远，频谱利用效率最高。并且在此实验数据下实现了600 Gbit/s传输系统48 h无误码长期稳定运行，这说明该入纤光功率和带宽可有效延长和提高600 Gbit/s通信系统的传输距离和频谱利用率。

【结论】

对于600 Gbit/s速率EON传输系统存在一个最佳入纤功率和滤波带宽，使得系统在不引起明显光纤非线性代价和通道串扰情况下传输距离最远，带宽利用率最大，文章提出的600 Gbit/s传输系统最佳入纤光功率和滤波带宽对600 Gbit/s传输系统的工程建设具有非常有意义的参考作用。

Abstract

【Objective】

The rapid development of data center networks necessitates intensive research into high-speed and high-capacity data center optical transmission systems. Single carrier 400 or 600 Gbit/s transmission will gradually become the mainstream transmission rate in the next generation of communication network. While the application of 400 Gbit/s transmission is well-studied in data center networks

detailed research on 600 Gbit/s transmission systems is less common.

【Methods】

This study is based on a single carrier 600 Gbit/s next-generation data center Elastic Optical Network (EON) transmission system

and conducts detailed theoretical analysis and experimental research on factors affecting transmission distance and spectrum utilization efficiency.

【Results】

The analysis shows that the maximum transmission distance is determined by the single carrier's peak input optical power

while the spectrum utilization efficiency is related to the bandwidth of the transmission channel. Experimental investigation is conducted on a single carrier 600 Gbit/s EON transmission system. By comparing the relationships between different fiber input optical powers

the system’s Q factor and the pre correction bit error rate

as well as the relationships between 3 dB channel filtering bandwidth and system’s Q factor for different channel numbers

it is confirmed that the system’s transmission distance and spectrum utilization efficiency are related to the optimal fiber input optical power and filtering bandwidth

respectively. Furthermore

the experiment shows that the optimal single-wave input optical power and optimal filtering bandwidth of the 600 Gbit/s transmission system are + 4 dBm and 77 GHz

respectively. Under these settings

the system achieves the longest transmission distance and the highest spectral efficiency. Under these experimental conditions

the 600 Gbit/s transmission system achieves long-term stable operation without error for 48 hours

indicating that this fiber input power and bandwidth can effectively extend and improve the transmission distance and spectrum utilization of the 600 Gbit/s communication system.

【Conclusion】

The 600 Gbit/s EON system has an optimal input power and filter bandwidth that maximizes bandwidth utilization and transmission distance without significant fiber nonlinear effects or channel interference. The findings have significant values for the engineering construction of 600 Gbit/s transmission systems.
