1. A sending method for adapting a payload bandwidth for data transmission, comprising:

  • acquiring N 66B coding blocks each of which contains 64B, wherein the N 66B coding blocks are obtained through a 64B/66B encoding scheme, N is an integer and 5≦

    N≦

    8;

    encoding the acquired N 66B coding blocks into a (64*N+1)B coding block; and

    sending the (64*N+1)B coding block obtained by encoding;

    wherein encoding the acquired N 66B coding blocks into the (64*N+1)B coding block comprises;

    decoding the N 66B coding blocks to obtain data blocks containing data only and different types of control blocks each of which contains at least one control characters;

    placing the control blocks into a control block buffer as a control block group, setting a first identifier to identify the control block group, setting a second identifier to identify a last control block in the control block group, and placing the data blocks, as a data block group, into a data block buffer;

    setting a third identifier by using four bits of each control block to identify a block type of each of the control blocks; and

    setting a fourth identifier by using a space smaller than or equal to three bits of each control block to identify positions of each of the control blocks in the N 66B coding blocks.
