摘要
随着波分复用(WDM)、偏振复用(PDM)和高阶调制等技术的使用，单模光纤的传输容量已经快速接近其香农极限。目前有望突破该极限的方法是空分复用(SDM)，这使得多模光纤重新受到关注。基于多模光纤的多输入多输出(MIMO)技术是解决信息爆炸式增长的新领域。研究并比较了光MIMO系统的各种实现方式，其中重点介绍了模群分集复用(MGDM)技术；同时也阐述了相干多输入多输出系统(COMIMO)相应的内容。最后指出多模光纤MIMO系统中存在的问题，以期对以后的研究有所裨益。
Abstract
As the wide application of wavelength division multiplexting (WDM), polarization division multiplexing (PDM) and high-order modulation techniques, the transmission capacity over single mode fiber is rapidly reaching its Shannon limit. The only known way to overcome this limit is space-division multiplexing (SDM), which causes a significant resurgence of research interest in the multimode fibers. The multiple-input multiple-output (MIMO) technique based on multimode fiber is a new area to answer explosive growth demand for transmission capacity. Implementations of optical MIMO, coherent optical MIMO (COMIMO) systems and highlight mode group division multiplexing (MGDM) are studied and compared. Meanwhile, some problems existing in the multimode fiber MIMO system are discussed to provide a help for further research.
