Abstract
This application provides a data transmission method, a communication apparatus, and a communication system. The method includes: generating N ciphertext data flows, where a first ciphertext data flow is any one of the N ciphertext data flows. The first ciphertext data flow includes at least two first alignment markers AMs, at least two encryption parameter sets, and at least two ciphertext data segments. One ciphertext data segment and one encryption parameter set are included between every two first AMs. The at least two first AMs are used for data alignment of the N ciphertext data flows. The method further includes sending the N ciphertext data flows. The data transmission method may be applied to a physical layer of an optical module or a network device.
