Description

PON的通道建立方法、ONU、OLT及系统 技术领域
本申请涉及但不限于无源光网络(Passive Optical Network，PON)通信领域，尤其涉及一种PON的通道建立方法、ONU、OLT及系统。
背景技术
随着通信网络技术的发展，可以利用网络传输大量的语音、数据、视频等业务，因此对带宽的要求不断提高，PON就是在这种需求下产生的。
图1为PON系统的拓扑结构图。如图1所示，PON系统通常由局侧的光线路终端(Optical Line Terminal，OLT)、用户侧的光网络单元(Optical Network Unit，ONU)和光分配网络(Optical Distribution Network，ODN)组成，通常采用点到多点的网络结构。ODN由单模光纤和光分路器、光连接器等无源光器件组成，为OLT和ONU之间的物理连接提供光传输媒质。为了在节省光纤资源情况下提升线路速率，提出了在一根光纤中多个波长上同时传输数据，同一波长上不同ONU的数据下行采用时分复用方式，上行采用时分复用接入方式，这称为波分时分PON系统。图2为波分时分PON系统的拓扑结构图。如图2所示，每个OLT管理多组ONU，在同一上行波长和下行波长上一组ONU发送上行数据的上行波长相同，并且接收下行数据的下行波长也相同，不同上行波长和下行波长上ONU组发送上行数据的上行波长不同，并且接收下行数据的下行波长也不同。
为了支持ONU能够传输超过单通道速率的数据，提出了ONU可以支持在多组通道上同时发送和接收数据。在同一个ODN中所有支持通道绑定的ONU为同一类型，支持多个相同的通道，OLT和ONU不需要交互ONU的工作通道信息，就可以完成该ONU的通道绑定；该方式中，ONU的类型单一，支持的应用场景少，为了在同一个ODN中可以支持多种类型的用户，要求同一个ODN中可以同时工作多种类型的ONU，不同类型的ONU支持的通道数不同，并且由于ONU支持的通道数可能大于OLT能够支持的通道数，所以OLT需要命令ONU工作在OLT支持的工作通道上。在上述需求 下，OLT如何获得ONU支持的通道，OLT和ONU如何建立该ONU可以工作的多个绑定的工作通道目前尚未解决。
