【摘要】 介绍了EPON上行接入的关键技术———测距、注册以及带宽分配。提出了一种上行接入技术的实现方案。通过硬件电路仿真验证了光网络单元(ONU)可以收到正确的时隙,从而确保ONU能够以TD MA方式完成上行接入。更多还原

【Abstract】 Key technologies of EPON upstream access, such as ranging, registering, and bandwidth allocating, are introduced,and the implementation of upstream access is proposed in this paper. Hardware simulation demonstrates that each ONU (optical network unit) can receive correct time slot to achieve upstream access.更多还原
