Abstract
Hollow core fibers are unique in reducing signal latency, as well as providing low dispersion and low nonlinearity. Their adoption is hindered by cost, particularly for complex structures that provide the lowest loss. Designs of antiresonant nodeless fiber (ANF) with uniformly sized capillaries, symmetric structures , and without nesting have simple structures that could more readily achieve commercial exploitation. We investigate simple ANF structures for short-reach applications where reduced latency is critical and transmission lengths are short enough to allow a trade-off on loss. A common design rule in ANF targets a ratio of 0.68 for capillary diameter to core diameter . We find that when such a design is combined with a large core diameter, the fiber is highly sensitive to bending orientation. We identify ANF designs that offer single-mode operation with acceptable loss, as well as robustness to bending radius and orientation. When there is no bending, our best design has a simulated loss of ≤ 7 dB/km at the worst-case C-band wavelength. At bending radii of 21 and 18 cm, the worst-case loss over all bending orientations and throughout the C-band is 14.5 and 17.52 dB/km, respectively. Higher-order mode suppression exceeds 20 dB under all conditions (bending and wavelength).

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
