In this work, we propose design parameters for optimized high-density optical cables to control the spatial-mode dispersion (SMD) of randomly coupled multi-core fibers (MCF). The analytical results of our proposed cable demonstrated the controllability of the bending and twisting of the implemented optical fibers by means of tension that is applied for a bundled fiber while keeping the sufficient reliability. An optical characterization showed that appropriate cabling parameters resulted in SMD controllability and a 47% reduction of the SMD coefficient while avoiding undesired loss increase. C-L band transmission experiments using our optical cable showed no degradation of the Q-factor or mode-dependent loss (MDL). Our proposed cable design is beneficial for achieving an SMD-managed large-capacity and long-haul transmission link.

控制随机耦合多芯光纤空间模色散的高密度光缆参数设计

在这项工作中，我们提出了用于优化高密度光缆的设计参数，以控制随机耦合多芯光纤（MCF）的空间模式色散（SMD）。我们提出的电缆的分析结果表明，通过施加在成束光纤上的张力，可实现光纤弯曲和扭曲的可控性，同时又保持了足够的可靠性。光学特性表明，适当的布线参数可导致SMD可控性和SMD系数降低47％，同时避免了不必要的损耗增加。使用我们的光缆进行的CL波段传输实验没有显示Q因子或模式相关损耗（MDL）的下降。我们提出的电缆设计有益于实现SMD管理的大容量和长距离传输链路。
