Space-division multiplexing (SDM) technology has a promising role in overcoming the so-called “capacity crunch” of existing single mode fiber (SMF). Now, researchers in China experimentally demonstrated an orbital-angular-momentum (OAM) mode based SDM transmission system with a total capacity over 1-Pb/s. The result has significant potential for further up-scaling communication capacity by exploiting the OAM modes in optical fibers while keeping multi-input multi-output (MIMO) processing to an ultra-low level of complexity.
