摘　　要：PON技术是下一代光接入网发展的关键技术,目前发展的PON技术主要是EPON和GPON。EPON是基于Ethernet的PON,因其成本低、容易运行和维护等优点而被称为下一代光接入网的首选;GPON英文全称为Gigabit-capable Passive Optical Network,它能为数据、TDM以及各种QoS业务提供很好的支持,是一种很有前途的光接入网技术。文中在简单介绍EPON和GPON基本工作原理的基础上,对EPON和GPON目前提出的动态带宽分配算法进行比较。PON technology is the key technology for the development of next-generation Optical Access Network. At present, it mainly includes EPON and GPON. EPON is the PON based on Ethernet. Due to its low cost, easy implementation and maintenance, EPON is regarded as the best choice for next-generation Optical Access Network. GPON is the abbreviation for Gigabit-capable Passive Optical Network. GPON could provide strong support for data, TDM and various QoS business. Consequently it is a technology with great potential for Optical Access Network. Based on introduction of fundamental principles of EPON and GPON, this paper compares the present dynamic bandwidth allocation algorithms of EPON and GPON.
