本文实验演示了采用非模式选择性3D波导光子灯，在常规50微米渐变折射率(GI)多模光纤(MMF)的3个空间模上传输符合IEEE 802.11ac标准的3空间流无线局域网信号的空分复用(SDM)传输。通过测量每个流的误差向量幅度(EVM)性能和信道矩阵的条件数(CN)，研究了两种情况，包括纯光纤传输和光纤-无线混合传输。实验结果表明，在0~6 GHz范围内，基于SDM的MMF链路可以在长达1 km的光纤上提供CN<；20db的良好MIMO信道，在2.4 GHz、5.8 GHz和200m MMF链路上分别获得2.38%、2.97%和2.11%的EVM性能。这些结果表明，有可能将无线MIMO信号分发到现有的建筑物内商用MMF上，从而极大地节省成本。
In this paper, we experimentally demonstrate space-division-multiplexed (SDM) transmission of IEEE 802.11ac-compliant 3-spatial-stream WLAN signals over 3 spatial modes of conventional 50um graded-index (GI) multimode fiber (MMF) employing non-mode-selective 3D-waveguide photonic lantern. Two kinds of scenarios, including fiber-only transmission and fiber-wireless hybrid transmission, were investigated by measuring error vector magnitude (EVM) performance for each stream and condition number (CN) of the channel matrix. The experimental results show that, SDM-based MMF link could offer a CN< 20dB well-conditioned MIMO channel over up to 1km fiber length within 0-6GHz, achieving as low as 2.38%, 2.97% and 2.11% EVM performance for 1km MMF link at 2.4GHz, 5.8GHz, and 200m MMF link followed by 1m air distance at 2.7GHz, respectively. These results indicate the possibility to distribute wireless MIMO signals over existing in-building commercially-available MMFs with enormous cost-saving.
