    Abstract: An embodiment of the present disclosure contemplates a data sending and receiving method and apparatus. 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; 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; 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.

    Abstract: The present invention provides a data processing method and device. A data processing device receives a first data stream, where the first data stream includes a first data unit; obtains a boundary of the first data unit; obtains a first skew according to a first data amount and the boundary of the first data unit; and adjusts the first data stream according to the first skew, so that a difference between the boundary of the first data unit and a boundary of the first data amount is a length of an integral quantity of first data units, so that a relatively small amount of data is needed in such an adjustment, that is, one data stream is adjusted, and an adjusted data stream can meet a basic condition for multiplexing, which reduces operation complexity and costs and is beneficial to deploy and implement bit width conversion.

    Abstract: A data processing method, a data transmit end, and a data receive end are presented. The data processing method includes inserting multiple alignment markers (AMs) into a first data stream, where the first data stream is a data stream that is transcoded and scrambled after being encoded at a physical layer; adaptively allocating the first data stream that includes the AMs to multiple physical coding sublayer (PCS) lanes to obtain second data streams; performing forward error correction (FEC) encoding on the second data streams on the multiple PCS lanes to obtain third data streams; and delivering the third data streams to multiple physical medium attachment sublayer (PMA) lanes according to an input bit width of a Serdes to obtain multiple fourth data streams, each fourth data stream includes at least one complete and continuous AM, and the at least one AM is an AM in the multiple AMs.
