Claim 0:
1. A method, comprising:
mapping an optical transport unit (OTU) signal to a plurality of forward error correction (FEC) frames, wherein a rate of the OTU signal is n times a benchmark rate, wherein a rate of a payload area of each of the plurality of FEC frames is mi times the benchmark rate, n≥2, X≥2, mi≥1, and, ∑
        
          i
          =
