摘要
无源光网络(PON,Passive Optical Network)采用无源光分/合路器或光耦合器分配/汇聚各光网络单元(ONU,Optical Network Unit)信号的光接入网。PON系统系由光线路终端(OLT,Optical Line Terminal)、光分配网(ODN,Optical Distribution Network)、光网络单元(ONU)组成的信号传输系统,简称PON系统。目前主流PON综合接入系统根据采用的技术分为以太网无源光网络(EPON,Ethernet Passive Optical Network)和吉比特无源光网络(GPON,Gigabit-capable Passive Optical Networks)。
PON adopts passive optical branch device or optical coupler distribution / convergence of the ONUsignal in optical access network. The PON （Passive Optical Network） system is an ONU signal transmission system composed of OLT （optical line terminal） ODN（optical distribution network） ONU （optical network unit）. The current mainstream PON integrated access system, according to the adopted techniques, could be defined as two categories of EPON and GPON.
