Matching characteristics of high-performance, low-cost, analog fiber-optic links for arrayed-antenna applications
Bibliographic record
Abstract
Two pairs of fiber-optic links are designed, built, and tested using directly modulated semiconductor laser diodes operating at a 1.3 μm wavelength. Delays of 5 μs are demonstrated, with a spurious free dynamic range of up to 115 dB/Hz2/3, a wide-frequency bandwidth of up to 6 GHz, and a pulse response of 120 ps, with very low pulse distortion. The matching characteristics of each pair are measured. Despite the fact that very different lasers are used, very good amplitude and phase matching of the fiber links is obtained. It is concluded that using the lasers from the same wafer would even further improve the matching, and would result in virtually unnoticeable amplitude and phase differences between channels. © 2000 John Wiley & Sons, Inc.

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.
