Abstract
A detailed experimental characterization of a polarization-independent all-optical 3R regenerator is presented. The regenerator is comprised of a self-pulsating distributed feedback laser for clock recovery, cross-phase modulation in a highly nonlinear fiber (HNLF) and offset spectral slicing for retiming, and self-phase modulation in an HNLF and offset spectral slicing for reshaping. A key feature of the regenerator is that polarization-independent operation is achieved without additional complexity as compared to a conventional polarization-dependent implementation. The regenerator performance is assessed for important properties of the input signal, including the optical signal-to-noise ratio, waveform distortion due to residual group velocity dispersion and polarization mode dispersion, state-of-polarization, power, and wavelength. With careful attention to key design parameters, excellent performance is achieved.

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
