Abstract
In this paper, we have designed two multi-core fibres (MCFs) structures with 31 and 37 trench-assisted and air-hole-assisted cores with reduced inter-core crosstalk (XT). The air-hole pairs and triplets are placed between adjacent trench-assisted cores in order to further suppress modal field overlap. The XT analysis of the 31-core design underlines the significance of enclosing the outer cores with the air-hole structure. The effect of core pitch on the XT is also investigated. Placing the low-index air-hole shield closer to the trench enhances the modal confinement within relatively large trench-assisted core structures. As a result, the lowest possible core-pitch MCF (air-holes touching outer trench boundaries) yielded a minimum inter-core XT of between −60 dB and −70 dB for 100 km of fibre length. Therefore, our 37-core MCF design is suitable for high-density space-division multiplexing applications.

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
