Full-duplex analog WiFi transport over RSOA-based wavelength-reused digital passive optical networks
Bibliographic record
Abstract
We experimentally demonstrated the transparent convergence of distributed antenna system in a digital wavelength division multiplexed passive optical network system employing reflective semiconductor optical amplifier (RSOA) at the remote antenna unit (RAU). The spurious free dynamic range and frequency response of the RSOA is measured to meet WiFi's requirements. RSOA's electrical-to-optical conversion efficiency improves significantly by down converting the WiFi signal to intermediate frequency band. By incorporating the up/down mixer in Central Office and RAU, we experimentally achieve full-duplex WiFi transmission along with 1 Gb/s downlink digital on-off-keying signal in single mode fiber up to 15 km (64QAM), 40 km (16QAM), and 60 km (QPSK) with 1 meter wireless path working in half-duplex mode. The bit-error-rate below the forward error correction threshold (2 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> ) is observed in all cases whereas the 1 Gb/s digital downlink signal is error-free up to 20 km of fiber.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
