1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The exponential growth of data capacity in intelligent terminals drives higher data traffic toward network edges. Compact I/O systems are essential to support space-constrained infrastructures at the computing edges or modular data centers. However, scaling high-capacity transmission via increasing physical channels is constrained by limited source coherence and low carrier-to-noise ratios (OCNR), hindering lightweight, efficient applications like distributed edge computing. Here, we exploit an integrated self-injection-locked dark-pulse microcomb to achieve 1 Tbps/λ/core transmission and characterize the constraints among OCNR, linewidth, and transmission rate. Furthermore, a multi-dimensional transmission architecture for multi-nodes aggregation is explored, boosting the transmission rate to 200 Tbps with 16 comblines at 70 Gbaud. Combining with integrated waveshapers and semiconductor optical amplifiers, a chip-level parallel carrier generator is explored, reducing system size a hundredfold while delivering 5 Tbps. Our results highlight significant potential for compact and resource-conserving transmission systems in data centers and distributed high performance computing applications.
