Abstract

Passive optical networks (PONs) are the most successful broadband access solutions for its wide bandwidth, low-cost deployment worldwide, and maintenance. In the last decade, the diverse and prevalent research related to PONs sustains 330+ science citation index (SCI) articles per year, with 9.18 average citations per article, making it "big literature data". This article, for the first time, presents the graphical representation of knowledge base, knowledge domain, and knowledge evolution of PON research using co-citation analysis based on 3381 SCI publications worldwide from 2010 to 2019 in bibliometric visualization tool- CiteSpace. The bibliographic analysis focused on 528 important research articles, 34 hotspots, 155 research frontier keywords, 481 core authors, 185 cited authors, 58 countries, 254 institutions, and 118 journals. Based on the frequency of keywords, Modulation, WDM PON, Transmission, Semiconductor optical amplifier, and Dynamic bandwidth allocation are the dominant and turning points in the structural basis of PON research. The most prominent research hotspots appearing in recent years are Energy efficiency, NG-EPON, and Chaotic encryption. The trend of future research on PONs is from TWDM PON issues, fronthaul implementation in NG-PON2, 5G-PON and encryption methods for physical layer security. The leading core authors, institutes, countries, and journals were also identified related to the PON research. This analysis would serve as a comprehensive guide on the status and future research trends on PONs for the aspirant researchers.

近十年无源光网络研究的文献计量分析与可视化

无源光网络(pon)是目前最成功的宽带接入解决方案，具有带宽宽、部署成本低、维护方便等优点。近十年来，与PONs相关的研究种类繁多、流行度高，每年SCI (science citation index，科学引文索引)文章达330余篇，平均每篇被引9.18次，是“大文献数据”。本文首次利用文献计量可视化工具CiteSpace对2010 - 2019年全球3381篇SCI论文进行共被引分析，对PON研究的知识库、知识领域和知识演变进行了图形化表示。共收录528篇重要研究论文、34个研究热点、155个研究前沿关键词、481位核心作者、185位被引作者、58个国家、254个机构、118种期刊。基于频率的关键词调制、WDM PON、传输、半导体光放大器和动态带宽分配是PON结构基础研究的主导和转折点。近年来出现的最突出的研究热点是能效、NG-EPON和混沌加密。未来对PON的研究趋势将从TWDM PON问题、NG-PON2的前传实现、5G-PON以及物理层安全的加密方法等方面展开。与PON研究相关的主要核心作者、研究所、国家和期刊也被确定。这一分析将为有抱负的研究人员提供关于pnas现状和未来研究趋势的全面指导。
