Claim 0:
1. A data transmission method, comprising:
performing, by a physical medium attachment (PMA) layer of a PHY chip of an ethernet device, bit-level demultiplexing processing on y first data streams to obtain x second data streams, wherein the y first data streams are based on bit-level multiplexing processing, where x and y are positive integers, and x>y;
performing, by the PMA layer of the PHY chip of the ethernet device, block-level multiplexing processing on the x second data streams to obtain z third data streams, where z is a positive integer, x>z, and z≥1; and
outputting, by the PMA layer of the PHY chip of the ethernet device, the z third data streams over z output lanes.
