摘要：
目前，EPON系统普遍采用的是两个波长的上下行链路设计，用来传送数据、语音和IP数字视频。系统带宽依赖于设备性能。为了低成本地提高系统带宽，本文提出结合粗波分复用CWDM技术，充分利用物理线路的潜能对EPON系统做了衍生，通过增加波长数量来扩展EPON系统的带宽。文章以三波长扩展为例论述了扩展方法。

Abstract:
Nowadays, EPON systems usually adopt the design of upstream and downstream to transfer data, audio and IP digital video. System band-width relies on t he functions of equipment. In order to increase the EPON system band-width in low cost, this article puts forward the technology of combining CWDM , suf ficiently uses the potential of the physical fiber to model economic ramifications that increase the number of wavelengths for transmission. In this paper, we present the method of ramification by the 3-wavelength system application.
