本文综述了空间分复用（SDM）传输的最新进展，并提出了具有30个以上空间信道的密度SDM (DSDM)，以实现超过pb /s的容量。此外，我们讨论了使用多核和/或多模光纤实现长距离DSDM传输系统的要求，包括功率和空间效率高的放大方案，使用具有大有效面积的光纤和具有低芯间串扰、低差分模式延迟（DMD）和低模式相关损耗（MDL）的传输线。具有低串扰、低DMD和低MDL、并行多输入多输出信号处理、低模相关增益掺铒光纤放大器和MDL均衡技术的梯度指数异构12芯× 3模光纤对于扩展多核和多模传输的范围具有重要意义。我们回顾了在12芯x 3模光纤上偏振复用16正交调幅信号的长距离传输实验。
In this paper, we review recent progress on space division multiplexed (SDM) transmission and our proposal of dense SDM (DSDM) with more than 30 spatial channels toward capacities beyond petabit/s. Furthermore, we discuss the requirements for realizing long-haul DSDM transport systems using multicore and/or multimode fiber, including power and space efficient amplification schemes, the use of fibers with large effective areas and transmission lines with low intercore crosstalk, low differential mode delay (DMD), and low mode dependent loss (MDL). Graded index heterogeneous 12-core x 3-mode fiber with low crosstalk, low DMD, and low MDL, parallel multiple-input and multiple-output signal processing, low mode dependent gain Erbium-doped fiber amplifiers, and MDL equalization technologies are significant as regards extending the reach of multicore and multimode transmission. We review our long-distance transmission experiment on polarization-division multiplexed 16-quadrature amplitude modulation signaling over 12-core x 3-mode fiber.
