Embodiments provide methods, apparatus and a computer programs for an optical communication system. Information on a desired reach of an optical signal is provided (12). Based on the desired reach, a combination of a modulation format and a forward error correction code for the optical signal is determined (14), wherein the modulation format is determined (141) from a plurality of modulation formats, wherein modulation symbols of different modulation formats comprise different numbers of bits, and wherein the forward error correction code is determined (142) from a plurality of different forward error correction codes having different code rates. |
