Abstract: Future flexible transceivers will be able to adjust modulation format, number of subcarriers, symbol rate, and forward error correction (FEC) scheme, according to channel and network conditions. This paper uses a combination of theoretical derivations and experimental results to recommend the best set of parameters to satisfy a specific demand to be routed along the network. In particular, for a given required transparent reach and desired net bit rate, and assuming an FEC scheme with a constant gap to capacity, the paper provides a set of modulation format, number of subcarriers, symbol rate, and code rate, which requires minimum bandwidth, while offering a conveniently low bit error rate (in optical systems, typically 10(-15)). We observed that optimum operating points required FEC schemes with overheads ranging from almost 0 to 145%, which is an important guideline for future flexible optical communications systems.
