研究目的
Investigating the mode retaining capability of strongly coupled multi-core fiber (MCF) to address the issue of mode crosstalk in regular multi-mode fiber, aiming to enhance transmission capacity within data centers through mode division multiplexing (MDM).
研究成果
The study demonstrated that strongly coupled MCF exhibits superior mode retention characteristics compared to regular multi-mode fiber, with a 5dB improvement at an 80 mm bending radius. This suggests the potential of strongly coupled MCF for reducing mode crosstalk in MDM systems within data centers, though further research is needed to optimize bending direction effects.
研究不足
The study was limited by the inability to control the fiber bending direction strictly to parallel arrangement in experimental work, which may have affected the mode retention characteristics observed. Additionally, the simulation and experimental results showed discrepancies possibly due to different fiber bending directions.
