无源光网络系统、光线路终端及光网络单元技术方案

本申请公开了一种PON系统、OLT及ONU，涉及光通信领域，所述PON系统包括：OLT和至少两个ONU，OLT与至少两个ONU之间通过一条下行通道和两条上行通道进行数据交互；OLT通过下行通道向各个ONU发送下行数据，下行数据中包括上行带宽授权，上行带宽授权用于控制ONU发送上行数据；ONU通过下行通道接收下行数据；根据下行数据中包含的上行带宽授权，通过第一上行通道或第二上行通道发送上行数据；OLT通过第一上行通道和第二上行通道接收各个ONU发送的上行数据；其中，第一上行通道关闭注册功能，第二上行通道开启注册功能。

Passive Optical Network System, Optical Line Terminal and Optical Network Unit

This application discloses a PON system, OLT and ONU, which relates to the field of optical communication. The PON system includes OLT and at least two ONUs. OLT and at least two ONUs interact with each other through one downlink channel and two upstream channels. OLT transmits downlink data to each ONU through downlink channel, downlink data includes upstream bandwidth authorization, and upstream bandwidth authorization is used to control ONU transmission. Uplink data; ONU receives downlink data through downlink channels; sends upstream data through the first or second upstream channels according to the upstream bandwidth authorization included in downlink data; OLT receives upstream data from each ONU through the first and second upstream channels; where the first upstream channel closes the registration function and the second upstream channel opens the registration function.
