摘要： 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.

摘要： Techniques are described for configuring an optical network unit (ONU) in a pre-burst state prior to transitioning the ONU to a burst-on state. During the pre-burst state, a laser emitter of the ONU stabilizes to its wavelength, thereby reducing the impact of wavelength drift when the ONU transitions to the burst-on state.

摘要： 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.
