Abstract
Simultaneous provision of multiple services using a centralized light source can greatly reduce the complexity and cost of a wavelength-division multiplexing passive optical network (WDM-PON). In this paper, we report two schemes to simultaneously provide an ultra-wideband (UWB) service and a wired service using a centralized light source. In one scheme, a UWB signal and a wired signal are multiplexed and modulated on a single wavelength in the center office for wireless and wired downstream services. In the other scheme, the wavelength from a UWB downstream signal is reused in the optical network unit to provide a wired upstream service. Both schemes are experimentally demonstrated with the data-transmission performance evaluated by measuring the electrical spectra, eye diagrams, and receiver sensitivities. The proposed schemes would greatly reduce the cost while significantly improving the spectrum efficiency of a WDM-PON network incorporating UWB-over-fiber (UWBoF) systems for broadband wireless access, making the WDM-PON network more attractive for practical deployment.

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
