摘要

2021年国际电联电信标准化部门（ITU-T）完成50 Gbit/s无源光网络（PON）的标准制定，当前设备商和运营商已经完成样机验证，ITU-T成立Beyond 50 Gbit/s PON讨论组开始研讨未来PON相关技术方案，因此Beyond 50 Gbit/s PON成为当前光通信领域的研究热点。根据前几代PON标准的速率演进规律推测，Beyond 50 Gbit/s PON的速率预计将超过100 Gbit/s。文章将分析超100 Gbit/s PON面临的问题和挑战，重点介绍灵活速率PON和相干PON架构这两个潜在技术路径及其关键技术方案，为未来超100 Gbit/s PON的研究和标准制定提供参考。

Abstract

In 2021

the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) developed the standards of 50 Gbit/s Passive Optical Network (PON). Currently

the equipment manufacturers and operators have completed prototype verification. ITU-T has established the Beyond 50 Gbit/s PON discussion group to explore future PON-related technical solutions. As a result

beyond 50 Gbit/s PON has become a research hotspot in the field of optical communication. According to the evolutionary pattern of previous PON standards

it is anticipated that the data rate of beyond 50 Gbit/s PON will exceed 100 Gbit/s. This article analyzes the problems and challenges faced by beyond 100 Gbit/s PON

focusing on two potential technological paths: flexible-rate PON and coherent PON architecture

along with their key technical solutions. This study provides references for future research and standardization of beyond100 Gbit/s PON.
