Claim 8:
9. A data transmission method, comprising:
obtaining, by a physical medium attachment (PMA) layer of a PHY chip of an ethernet device, z third data streams over z input lanes, wherein the z third data streams are based on block-level multiplexing processing, where z is a positive integer, x>z, and z≥1;
performing, by the PMA layer of the PHY chip of the ethernet device, block-level demultiplexing processing on the z third data streams to obtain x second data streams; and
performing, by the PMA layer of the PHY chip of the ethernet device, bit-level multiplexing processing on the x second data streams to obtain y first data streams, where x and y are positive integers, and x>y.
