基于多芯（MCF）或多模光纤（MMF）的空分复用（SDM）传输是克服标准单模光纤（SSMF）容量限制的最有前途的解决方案之一。本文的重点放在MMF传输的数据速率为100 Gb/s及以上，最近已经证明通过相干光OFDM（CO-OFDM）和单载波（SC）的超信道传输的基础上专门设计的少模光纤（FMF）。然而，要释放高数据速率SDM传输的全部潜力，需要从设备到系统级别的全新研究。在本文中，我们阐明了整体系统架构，关键组件和子系统模块的SDM传输和报告的最新演示SDM超信道传输。我们设想SDM和OFDM调制的组合可能是未来Tb/s和超越光传输的潜在关键路线。
Space-division multiplexed (SDM) transmission based on multi-core (MCF) or multi-mode fiber (MMF) emerges as one of the most promising solutions for overcoming the capacity limit of standard single mode fiber (SSMF). This paper places a focus on the MMF transmission for which a data rate of 100-Gb/s and beyond has been recently demonstrated through coherent-optical OFDM (CO-OFDM) and single-carrier (SC) superchannel transmission based on specially-designed few-mode fibers (FMF). However, to unleash the full potential of the high data rate SDM transmission requires brand-new research from device to system level. In this paper, we elucidate the overall system architecture, critical components and sub-system modules for SDM transmission and report the up-to-date demonstration of SDM superchannel transmission. We envisage that the combination of SDM and OFDM modulation could be a potential key route to the future Tb/s and beyond optical transports.
