摘要

【目的】

基于调顶技术的辅助管理和控制信道（AMCC）与承载数据业务无关，具有超低时延抖动的优点，契合接入网大带宽、低时延和智能化的发展趋势。文章旨在探讨光接入网中调顶AMCC技术的原理、实现方法和技术验证，深入分析了其在接入网中的新型应用，从而为其在接入网中的进一步研究开发和工程应用提供参考。

【方法】

文章通过文献综述和实验数据分析，对调顶AMCC的技术原理进行了系统性阐述。研究集中于探讨其在光接入网络中的低成本实现路径，包括直接调制激光器和分光探测器等技术。此外，还分析了调顶AMCC技术在不同接入光网络系统中的应用及其对网络性能的影响，并进一步阐述了相关技术在接入网系统中的多通道监测、反射和光功率推算以及时分复用（TDM）无源光网络（PON）静默窗口规避的应用方法。

【结果】

研究显示，调顶AMCC技术能在接入网中有效地提供有别于传统方法的支持多通道监测和管理的途径，特别是在第5代移动通信技术（5G）前传承载、光线路在线监测和低时延TDM PON系统中能够有较好地应用。调顶AMCC技术能在支撑网络高速率传输的同时，实现对光层通道的感知和管理，尤其在处理TDM PON静默窗口问题上展现了显著的技术潜力。

【结论】

调顶AMCC技术在一定程度上实现了高速数据和低速信号在接入网中的低成本多维复用，在光接入网中具有广泛应用前景，其在满足对网络的大带宽和低时延通信进行智能化水平管理的同时，还可在光层实现一定程度的感知。文章所提技术的实施有助于提高网络的效率和稳定性，能够顺应第5代固定网络增强（F5G-A）和未来第6代固定网络（F6G）的发展。若能对文章所提技术在PON拓扑结构、更多的调制格式和更多应用场景等方面进行进一步的研究以优化其性能和适应性，将能够推动其大力发展。

Abstract

【Objective】

The Auxiliary Management and Control Channel (AMCC) based on overmodulation technology is independent of the data service and has the advantage of ultra-low latency jitter

aligning with the development trend of access networks

which feature large bandwidth

low latency

and intelligence. This article aims to explore the principles

implementation methods

and technical verification of overmodulation AMCC technology in optical access networks

and provides an in-depth analysis of its novel applications in access networks. This serves as a reference for further research and development

as well as engineering applications of this technology in access networks.

【Methods】

Through a literature review and analysis of experimental data

the article systematically elaborates on the technical principles of overmodulation AMCC. The research focuses on exploring low-cost implementation pathways for it in optical access networks

including technologies such as direct modulation lasers and split detectors. The paper also analyzes the application of overmodulation AMCC technology in different optical network systems and its impact on network performance. It further discusses the application methods of related technologies in access network systems for multi-channel monitoring

reflection

optical power estimation

and the avoidance of Time Division Multiplexing (TDM) Passive Optical Networks (PON) silent windows.

【Results】

The study shows that overmodulation AMCC technology can effectively support multi-channel monitoring and management in access networks

distinguishing it from traditional methods. It is particularly applicable in The 5th Generation Mobile Communication Technology (5G) front-haul transmission

optical line reflection monitoring

and low-latency TDM PON systems. This technology supports high-speed network transmission while enabling the perception and management of optical layer channels

demonstrating significant technical potential in addressing TDM PON silent window issues.

【Conclusion】

The overmodulation AMCC technology can achieve low-cost

multidimensional multiplexing of high-speed data and low-speed signals in access networks to a certain extent. It has broad application prospects in optical access networks

enhancing the intelligent management level of networks while fulfilling requirements for large bandwidth and low-latency communication. Additionally

it facilitates perception at the optical layer. Implementing this technology can improve network efficiency and stability

meeting the developmental needs of The 5th Generation Fixed Network-Advanced (F5G-A) and The 6th Generation Fixed Network (F6G) in future. Further research on its application in PON structures

more modulation formats

and additional application scenarios could optimize its performance and adaptability

promoting its vigorous development.
