Passive optical networks (PONs) have been widely used in access networks and are today the access technology of choice for operators, especially when they need to build new infrastructure. Significant effort has been put in place across the years to scale the speed of passive optical networks. The super-PON concept has also been proposed in order to scale reach and customer aggregation of PONs. However, it did not produce any standardization efforts nor significant commercial deployments. In November 2018, the IEEE 802.3 Working Group formed the P802.3cs “Super-PON” Task Force to standardize a flavor of super-PON able to support an increased optical reach of up to 50 km and an expanded customer coverage of up to 1024 customers per fiber over a passive optical distribution network. A project with near identical objectives was later started in ITU-T Q2/SG15. This paper presents the latest updates from these industry standardization efforts, with special attention to the activity of the IEEE P802.3cs Task Force, and the technical reasoning behind some of the key decisions that have been made.

超级PON：接入网的演进[已邀请]

无源光网络（PON）已在接入网络中得到广泛使用，并且今天已成为运营商的首选接入技术，尤其是当他们需要建立新的基础架构时。这些年来，人们已经做出了巨大的努力来扩展无源光网络的速度。还提出了超级PON概念，以扩展PON的覆盖范围和客户聚合。但是，它没有做出任何标准化努力，也没有进行重大的商业部署。2018年11月，IEEE 802.3工作组成立了P802.3cs“ Super-PON”任务组，以标准化一种能够支持最大50 km的光学距离扩展和最大1024的客户覆盖范围的super-PON风格客户通过无源光纤分配网络上的每根光纤。ITU-T Q2 / SG15随后启动了一个目标几乎相同的项目。本文介绍了这些行业标准化工作的最新更新，特别关注IEEE P802.3cs工作组的活动以及已做出的一些关键决策背后的技术原因。
