摘要

新兴应用对提高速度、扩大带宽和降低延迟的需求不断增长,这不仅推动了最近先进算法的突破,而且促进了城域网和接入网的更紧密集成。本文提出了一种基于相干数字子载波复用技术的新型全光城域接入集成网络(MAIN)。这种特殊设计的结构可以有效地消除传统方案中光-电-光转换带来的延迟和抖动,同时节省波长资源。为了进行实验验证,我们成功地在我们提出的架构中演示了400G双向相干传输,其中包括城域网中的三个节点和接入网中的三个节点。并结合实验结果对传输过程中的相关问题进行了广泛的讨论。最后,我们使用DP-16QAM信号达到${4}\乘以{100};{\rm Gbps}$的聚合速率。通过将SOA集成到ONU的发射器中,可以实现32.6 dB的功率预算和29 dB的动态范围。此外,实验结果还表明,所提出的全光主架构可以与TFDM方案顺利结合,进一步增强了灵活性,这也为下一代相干城域网和接入网的进一步研究铺平了道路。

All-optical metro-access integration network bidirectional transmission enabled by coherent digital subcarrier multiplexing
The ever-increasing demand for improved speeds, expanded bandwidth, and reduced latency in emerging applications has not only driven the recent advanced algorithm breakthroughs but also fostered closer integration of metro and access networks. This work proposes a novel all-optical metro-access integration network (MAIN) enabled by coherent digital subcarrier multiplexing technology. This specially designed architecture can effectively eliminate the latency and jitters caused by the optical–electrical–optical conversion in the conventional scheme and save wavelength resources at the same time. For experimental validation, we successfully demonstrate 400G bidirectional coherent transmission within our proposed architecture, involving three nodes in the metro network and the access network as an example. Also, the related problems during the transmission are extensively discussed with the experimental results. Finally, we reach an aggregation rate of ${4} \times {100}\;{\rm Gbps}$ using a DP-16QAM signal. By integrating a SOA into the transmitter of the ONU, a power budget of 32.6 dB with a 29 dB dynamic range is achieved. In addition, the experimental results also show that the proposed all-optical MAIN architecture can be smoothly combined with the TFDM scheme to further enhance the flexibility, which also paves the way for further research on the next-generation coherent metro and access network.

期刊介绍: The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
