Conjecture on the cause of increasing HD-FEC throughput losses
The discussion concerns network throughput under ideal hard-decision forward error correction (HD-FEC) and soft-decision forward error correction (SD-FEC), with modulation formats…

Conjecture that the SD-FEC limit paradigm underestimates spectral efficiency for 2048QAM
SD-FEC limit conjecture. The use of the SD-FEC limit paradigm in the reported record results, where a pre-FEC BER threshold obtained for $4$ QAM was used for $2048$ QAM, is incorrect…
