Polarization Agnostic Frequency-Comb WDM Transmission Enabling Net 800 Gbps OOK and 1.6 Tbps PAM4
Bibliographic record
Abstract
Current and future radio access networks (RAN) require the placement of intensity modulation/direct detection (IM/DD) transceivers near the antenna atop outdoor radio tower masts. Hence, the transceiver is subject to high temperatures (85°C - 100°C), and the ambient outdoor environment, which can impact the performance of the carrier laser. Thus, to preserve the performance of the carrier laser, it is desirable to remotely operate the laser from the transceiver in RAN applications, at distances up to 1 km. However, due to the necessity of single-mode fiber (SMF) in RAN[3] , the carrier laser’s state of polarization (SOP) can fluctuate from the linear transverse electric state, inducing polarization-dependent loss (PDL) in typical silicon photonic (SiP) Mach-Zehnder modulators (MZMs).

How this classification was reachedexpand
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.
