this paper can be summarized into four aspects: (1) ONU auto discovery and register contention solution.───归纳起来，论文主要包括以下四个方面：(1)ONU的自动发现以及注册冲突避免。
communications equipment, including EPON communications equipment (OLT, ONU) and power line carrier communication equipment.───通信设备主要包括EPON通讯设备(olt、onu)及电力线载波通信机。
of the REGISTER_ACK, the discovery process for that ONU is complete, the ONU is registered and normal message traffic can begin.───ONU的发现进程完成，该ONU注册成功并且可以开始发送正常的消息流。
The communications equipment , including EPON communications equipment(OLT , ONU) and power line carrier communication equipment .───通信设备主要包括EPON通讯设备（OLT、ONU）及电力线载波通信机。
All transmissions in a PON are performed between Optical Line Terminal(OLT)and Optical Network Units (ONU).───在PON之间进行的所有发射的光线路终端（OLT）和光网络单元（ONU）。
Packets should be buffered in the ONU until the correct timeslot for this ONU arrives.───直到本ONU的数据包正确时隙的ONU应在缓冲到达。
At the ONU, the phase signal is converted into intensity signal by a polarizer.───在用户端的部份，以一个偏振片來解调，把相位讯号转成强度讯号。
This is in no way representative of the real network traffic and we did not simulate the ONU load of more then 62. 5%.───这是在没有真正的网络通信方式的代表，我们没有模拟负载更多然后ONU的62.
In the upstream direction (from user to network), each ONU will use a separate TDM channel.───在上游方向，从用户（网络），每个ONU将使用一个单独的TDM通道。
When the grant arrives, the ONU transmits frames at wire speed during its assigned time slot.
The location of fiber user terminal equipment (ONU/ONI) has a bearing on the networking architecture and cost in applications.
The paper introduces main EPON technology, which includes ranging, ONU joining and upstream transmit alignment, etc. It also introduces EPON testing methodology and IXIA test solution.
This arbitration is achieved by allocating a transmission window ( grant ) to each ONU.
