A data transmission method, apparatus, and system can implement stable and reliable data transmission between Ethernet devices by using an optical switching device. The method includes: acquiring, by a transmit end device, first data; performing first scrambling processing on the first data by using a scrambler, so as to generate second data; generating, according to the second data, an optical data packet that includes an optical data frame, where the optical data frame includes a field of a first preamble; and sending an optical signal that carries the optical data packet to a optical switching device, so that the optical switching device performs switching processing on the optical signal, so as to send the optical data frame to a second Ethernet device. By adding a preamble in front of second data, an optical switching device and a receive end device can complete, by using the preamble, restoration and adjustment on a burst signal before the second data arrives, which can avoid a receiving error of an Ethernet device that can recognize only continuous signals. |
