An embodiment of the present invention discloses a data sending and receiving method. A first FEC unit of a sending device sends, by using a first channel, a first data stream on which first FEC encoding has been performed, where the first data stream includes a channel identifier of the first channel; a second FEC unit of the sending device sends, by using a second channel, a second data stream on which second FEC encoding has been performed, where the second data stream includes a channel identifier of the second channel; and the sending device performs interleaving on the first data stream and the second data stream, to obtain an output data stream, and sends the output data stream to a receiving device. The receiving device may perform de-interleaving on the data stream after the interleaving, and send at least data streams obtained through the de-interleaving to different FEC units for decoding, which improves an error correction capability of the receiving device. In addition, in the present invention, an operation of writing by row and reading by column does not need to be performed. Therefore, no delay is generated. |
