Abstract
We develop a new family of high-weight two-dimensional wavelength-time codes for optical code-division multiple-access (OCDMA) that takes advantage of the antipodal signaling enabled by differential detection and uses relaxed auto- and cross-correlation constraints. We analyze the performance of the proposed codes and examine how the code size and correlation properties affect two important system parameters, namely the maximum number of codes that can be generated and the bit error rate as a function of the number of active users. We also show that this new family of codes can be used to implement high-performance OCDMA systems when combined with forward error correction coding: a system with 32 wavelengths and 41 time chips operating at OC-3 transmission rates (155.52 Mb/s) can support an aggregate throughput of /spl ap/41 Gb/s.

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
