Abstract：With the development of communication technology and the increasing demand for smart campuses, traditional campus networks are also faced with major challenges such as insufficient bandwidth, inflexible networking, and difficulty in accessing the Internet of Things. In recent years, the industry has introduced network technologies such as PON and WDM in the campus network, or improved and optimized the existing Ethernet technology to deal with the problems and challenges. This paper summarizes the representative networking solutions in the industry, analyzes the technical principles, characteristics, and networking technology advantages and disadvantages, and uses the campus network scene as standard to judge and summarize the adaptability respectively, so as to achieve the comparison and judgment of technological advancement. Through the comparison, the shortcomings of the existing technology and the advantages and disadvantages of the new technology can be more deeply understood, in order to be used as a reference for solution selection in the future network construction.

园区网络相对于广域网是承载企业内部数据通信的网络，从校园到工业园区，再到酒店房间、医疗诊室，都属于园区网络范畴。
随着通信技术的发展和智慧园区类需求的不断增加，传统园区网络也面临着重大挑战，主要体现在：带宽升级难、难以扩展、继承性差；多网并存、管理复杂；物联网化；园区传输覆盖范围有限；成本和功耗较高等。面对以上种种挑战，多种基于光通信技术的园区网方案争相推出。本文主要目的即是分析相关通信技术和方案，给出各个技术和方案的适用场景对比分析。
