While the idea of wavelength-division multiplex passive optical network (WDM-PON) has been around for many years, it has never been taken up in a significant way, mostly due to a lack of demand for its level of bandwidth. Fifth generation (5G) wireless has brought with it new centralized architectures that seem to require very-high-performance fixed networks. This article considers the use of WDM-PON for 5G wireless, the key finding is that its suitability depends on the deployment scenario for the service area in question. There are places that could benefit from such a system. The results of an initial trial of this technology are provided, proving system feasibility. A new type of hybrid PON system architecture combining WDM-PON and 50 Gb/s time-division multiplex PON (TDM-PON) networking is discussed.

用于 5G 无线前传的 WDM-PON


虽然波分复用无源光网络 (WDM-PON) 的想法已存在多年，但从未得到广泛采用，主要是由于对其带宽水平缺乏需求。第五代（5G）无线带来了新的集中式架构，似乎需要非常高性能的固定网络。本文考虑将 WDM-PON 用于 5G 无线，主要发现是其适用性取决于相关服务区域的部署场景。有些地方可以从这样的系统中受益。提供了该技术的初步试验结果，证明了系统的可行性。讨论了一种结合 WDM-PON 和 50 Gb/s 时分复用 PON (TDM-PON) 组网的新型混合 PON 系统架构。
