    • An optical network comprises a plurality of optical network units and an optical line terminal having one or more transmitters and one or more receivers. Each of the one or more transmitters and each of the one or more receivers is configured to operate over a respective wavelength. Each of the optical network units has a respective laser that is optically coupled to a respective one of the one or more transmitters and a respective one of the one or more receivers. The optical line terminal is configured to monitor power levels of respective optical signal burst transmissions from each of the plurality of optical network units and to direct each optical network unit to wavelength bias its respective laser based on the monitored power levels to compensate for a respective wavelength shift experienced by the respective laser during burst transmissions.

    • A method of ranging comprises broadcasting a discovery request to a plurality of optical network units and receiving a respective discovery response from one or more of the plurality of optical network units. Each respective discovery response is transmitted as an out-of-band signal. The method also comprises approximating a respective out-of-band round trip delay to each corresponding optical network unit based on the respective discovery response; dynamically adjusting a size of a respective quiet window for each optical network unit based on the approximated out-of-band round trip delay; determining when to start the quiet window for each corresponding optical network unit based on the respective approximated out-of-band round trip delay; receiving an in-band ranging signal from the corresponding optical network unit during the respective quiet window; and determining an in-band round trip delay estimate based on the in-band ranging signal received during the respective quiet window.
    • 一种测距方法包括将发现请求广播到多个光网络单元并从多个光网络单元中的一个或多个接收相应的发现响应。 每个相应的发现响应作为带外信号发送。 该方法还包括基于相应的发现响应近似到每个对应的光网络单元的相应的带外往返延迟; 基于近似的带外往返延迟来动态地调整每个光网络单元的相应安静窗口的大小; 基于相应的近似带外往返延迟来确定何时启动每个对应的光网络单元的安静窗口; 在相应的安静窗口期间从对应的光网络单元接收带内测距信号; 以及基于在相应的安静窗口期间接收到的带内测距信号来确定带内往返行程延迟估计。

    • One or more devices of a network having asymmetric delay are configured to participate in time synchronization protocol sessions in which a client device synchronizes its local clock to a master device. In one example, a system includes an optical line terminal configured to receive a time synchronization protocol packet from a grandmaster clock and an optical network unit (ONU) configured to calculate a residence time of the time synchronization protocol packet, encode the residence time into the packet, and to forward the packet to a client device. Moreover, the system may participate in a plurality of time synchronization protocol sessions with a plurality of client devices, such that the client devices become synchronized in frequency and phase.
    • 具有不对称延迟的网络的一个或多个设备被配置为参与时间同步协议会话,其中客户端设备将其本地时钟同步到主设备。 在一个示例中,系统包括被配置为从大师时钟接收时间同步协议分组的光线路终端和被配置为计算时间同步协议分组的停留时间的光网络单元(ONU),将停留时间编码到 分组,并将数据包转发到客户端设备。 此外,系统可以参与与多个客户端设备的多个时间同步协议会话,使得客户端设备在频率和相位上变得同步。
