We carried out 20×12.5Gbit/s optical mode group division multiplexing communication using a plastic optical fiber in the order of meters at 1.55µm. We split lower-order and higher-order propagation modes of a graded-index plastic fiber in two groups and assigned these groups with different communication signal channels. The two mode groups were excited with a fan-in/fan-out device developed for optical space division multiplexing communication using a silica optical fiber and were demultiplexed with optical-domain spatial filtering. Obtained bit error rates of all the demultiplexed signals were below the 7% overhead hard-decision FEC threshold (3.8×10-3).
