摘要

通过在垂直腔面发射激光器和标准硅基梯度指数（GI）塑料光纤（POF）之间插入低噪声梯度指数（GI）塑料光纤（POF），与仅使用硅基梯度指数MMF作为传输介质相比，多模光纤（MMF）链路中的数据传输得到了显著改善。所研制的低噪声GI POF表现出与纤芯材料微观非均质结构密切相关的强模耦合；这有效地降低了MMF链路中的干涉噪声。实验结果表明，在采用四电平脉冲幅度调制的53.125 Gb/s数据传输中，低噪声GI POF的插入使误码率降低了几个数量级，尽管存在插入损耗，但由于具有明显的噪声抑制作用。这种简单的配置减少了收发模块和精确连接器设计中额外的噪声缓解需求，在确保稳健可靠运行的同时，实现了MMF链路的经济高效实施。

Stabilization of Multimode Fiber Link by Simple Insertion of Low-Noise Plastic Optical Fiber

Data transmission in a multimode fiber (MMF) link is significantly improved by simply inserting a low-noise graded-index (GI) plastic optical fiber (POF) between a vertical-cavity surface-emitting laser and standard silica GI MMF, compared with using only the silica GI MMF as a transmission medium. The developed low-noise GI POF exhibits strong mode coupling closely related to the microscopic heterogeneous structures in the fiber core material; this effectively reduces interferometric noise in the MMF link. Experimental results demonstrate that the insertion of the low-noise GI POF reduces the bit error rate by several orders of magnitude in 53.125 Gb/s data transmission using four-level pulse amplitude modulation, owing to significant noise suppression despite the presence of insertion loss. This simple configuration reduces the need for additional noise mitigation in transceiver modules and precise connector designs, enabling cost-effective implementation of MMF links while ensuring robust and reliable operation.
