Abstract
In this paper, we mathematically derive the probability density function (PDF) of the received electrical signal for coherent fiber-optic transmission systems. Both amplified spontaneous emission (ASE) noise and fiber nonlinearity are taken into account. The results show that the PDF of a bit ldquo0rdquo or ldquo1rdquo is asymmetric when intra-channel four-wave mixing (IFWM) is dominant. However, the PDF becomes nearly symmetric when the variance of ASE is much larger than that due to IFWM. The standard deviation of the received signal is calculated analytically. It is shown that the variance varies quadratically with launch power. We also investigate the optimum system scheme, including optimum dispersion map and pre-compensation ratio, for the coherent fiber-optic systems based on analytically calculated variance of IFWM.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
