A data transmission method, device and system, which can achieve stable and reliable data transmission between Ethernet devices through an optical switching device. The method comprises: a sending end device acquiring first data; conducting first scrambling processing on the first data by a scrambler, so as to generate second data; according to the second data, generating an optical data package comprising an optical data frame, wherein the optical data frame comprises a first lead code field; sending an optical signal which bears the optical data package to an optical switching device, thereby facilitating the optical switching device in switching the optical signal, so as to send the optical data frame to a second Ethernet device. By adding the lead code in front of the second data, the optical switching device and a receiving end device can complete the recovery adjustment on a burst signal before the second data arrives through the lead code, and the Ethernet device which can only identify a continuous signal can be prevented from generating a reception error. |
