An FEC coding/decoding data processing method and a related apparatus are provided. The method includes: performing, at an FEC coding processing sublayer by using m data code blocks as one group, FEC coding on a data code block sequence output by a physical coding sublayer, to generate n FEC check code blocks; respectively distributing m×t2 data code blocks and n×t2 FEC check code blocks to M virtual channels of a first virtual channel group and N virtual channels of a second virtual channel group; and respectively multiplexing, according to geared speed bit by bit multiplexing, data distributed to the first virtual channel group and data distributed to the second virtual channel group to at most H interfaces of a first physical channel group and at most K interfaces of a second physical channel group, where M is an integral multiple of H, and N is an integral multiple of K. |

1. A forward error correction (FEC) coding data processing method, comprising:
performing, at an FEC coding processing sublayer by using m data code blocks as one group, FEC coding on a data code block sequence output by a physical coding sublayer, to generate n FEC check code blocks, wherein both m and n are positive integers; respectively distributing m×t2 data code blocks and n×t2 FEC check code blocks to M virtual channels of a first virtual channel group and N virtual channels of a second virtual channel group, wherein m×t2 is less than or equal to m_max, m_max is t1 times the value of M, n×t2 is less than or equal to n_max, n_max is t1 times the value of N, and t1 and t2 are positive integers; and respectively multiplexing, according to geared speed bit by bit multiplexing, data distributed to the first virtual channel group and data distributed to the second virtual channel group to at most H interfaces of a first physical channel group and at most K interfaces of a second physical channel group, wherein M is an integral multiple of H, and N is an integral multiple of K. |
