Claim 12:
13. The method according to claim 12, wherein the x second data streams comprise data of a plurality of FEC codewords, and wherein before performing FEC codeword error correction processing on the x second data streams to obtain the x error-corrected second data streams, the method further comprises:
performing demapping processing on the x second data streams at a granularity of FEC symbols to obtain data expressed in FEC codewords; and
wherein performing FEC codeword error correction processing on the x second data streams to obtain the x error-corrected second data streams comprises:
performing FEC codeword error correction processing on data expressed in FEC codewords to obtain error-corrected data; and
performing mapping processing on the error-corrected data at the granularity of FEC symbols to obtain the x error-corrected second data streams.
