Abstract: A dummy optical signal generation apparatus includes a multi-longitudinal mode laser configured to provide a light source signal. The dummy optical signal generation also includes a comb optical bandpass filter. The light source signal provided by the multi-longitudinal mode laser outputs a dummy optical signal through the comb optical bandpass filter. The dummy optical signal is an optical signal that does not comprise service information.

Abstract: Embodiments of this application disclose a method, an apparatus, and a system for implementing data transmission. The method includes: obtaining, by a sending device, a data packet in a target data flow; and sending the data packet through each of at least two physical links between the sending device and a receiving device, where the data packet sent through each of the at least two physical links includes a same sequence number. Because the data packet in the target data flow is sent through different physical links, not through only one physical link, when a transmission latency of the data packet is increased due to a bandwidth instability factor such as burst traffic or electromagnetic wave interference on any physical link, the receiving device can combine, into a target video flow, data packets that are sent through other physical links and that have a lower latency.

Abstract: Embodiments of the application provide a data transmission method and a device. A sending device periodically obtains a first packet sequence number and a second packet sequence number. The first packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to a first data flow and that are received by a receiving device through a first data channel in a statistics period. The second packet sequence number is a maximum value in packet sequence numbers respectively corresponding to packets that belong to the first data flow and that are received by the receiving device through a second data channel in the statistics period. The sending device updates a packet cache queue of: the first data channel, the second data channel, or both the first and the second data channels, based on the first packet sequence number and the second packet sequence number.
