摘要
随着接入网业务需求和技术手段的快速发展,各种光无源接入网(PON)技术日趋成熟。一些新型的信息处理技术如波分复用技术(WDM)、多发多收技术(MIMO)、正交频分复用技术(OFDM)、混合调制等,在无线、光骨干网以及其他领域的理论和应用也日益完善,将它们应用在接入网领域有望解决目前PON 的技术瓶颈,改善PON 系统的整体性能。讨论和分析了这些新型信息处理技术的原理,将其应用于PON 中的方式以及优缺点,以期为未来的研究提供参考。
Abstract
As the development of service needs and approaches,kinds of passive optical network (PON) technologies make a big progress. At the same time,some new information processing technologies such as wavelength division multiplex (WDM),multi -input and multioutput (MIMO),Orthogonal freqnency division multiplexing (OFDM) combined modulation and so on,are introduced and being optimized in wireless communication,optical main links and other fields. Employing such new technologies in PON,promises to solve the present technological bottlenecks in PON and optimize the whole system's performance. The principles of those technologies,how they can be used in PON and their advantages as well as shortcomings are discussed and analyzed,to provide a reference for future research.
