无源光网络（脑桥）已广泛应用于接入网络中，并且是当今运营商的首选接入技术，特别是当他们需要建立新的基础设施时。多年来，人们已经做出了大量努力来扩展无源光网络的速度。还提出了超级PON概念，以便扩展脑桥的覆盖范围和客户聚集。然而，它没有产生任何标准化工作，也没有重大的商业部署。2018年11月，IEEE 802.3工作组成立了P802.3cs“Super-PON”任务组，以标准化一种超级PON，能够支持最多50公里的光纤覆盖范围，并通过无源光分配网络扩展客户覆盖范围，每根光纤最多可覆盖1024个客户。后来在ITU-T第2季度/第15研究组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进展，特别关注IEEE P802.3cs工作组的活动，以及一些关键决策背后的技术推理。(C)2020美国光学学会
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.
