光接入网中的ECDM-PON技术(本期优秀论文)

摘要

Passive optical networks based on Electrical Code Division Multiplexing is a new type of optical ac-cess networks technology. In this paper, first the basic structure of ECDM-PON is introduced, then the key technologies of ECDM-PON is analyzed, especially the new type of correlation and decision technologies based on CCD-MF and the character of ultra long distance transmission. At last, future applications of ECDM-PON is simple introduced.%基于电码分多址的无源光网络是一种新型的光接入网技术.文章首先介绍了ECDM-PON的基本结构,然后分析了ECDM-PON的关键技术,特别是以CCD-MF为基础的新型的相关和判决技术,以及超长距离传输的特点.最后,展望了ECDM-PON的应用前景.
