Claim 11:
12. The optical signal transmission method of claim 1, further comprising:
mapping a third ODU frame to a second TUflex frame;
mapping the second TUflex frame to a second OPU frame, wherein a plurality of payload blocks comprised in the second TUflex frame are distributed in a payload area of the second OPU frame, wherein P2=P1*R2/R1, wherein the R1 is a bit rate of the first OPU frame, wherein the R2 is a bit rate of the second OPU frame, wherein the P1 is a first quantity of payload blocks comprised in a transmission period of the first OPU frame, wherein the P2 is a second quantity of payload blocks comprised in a transmission period of the second OPU frame, wherein a third quantity of the payload blocks in the second TUflex frame is the same as a fourth quantity of the payload blocks, and wherein the third ODU frame and the first ODU frame are used to bear service data of a same client;
mapping the second OPU frame to a fourth ODU frame, wherein a bit rate of the fourth ODU frame is greater than a bit rate of the third ODU frame;
mapping the fourth ODU frame to a second OTU frame; and
sending the second OTU frame.
