Space-time block codes can extend the optical signal to noise ratio tolerance in multiple-input multiple-output optical coherent spatial division multiplexing transmission systems with respect to single-mode transmission performance. The OSNR tolerance gain is achieved through exploiting the spatial diversity few-mode-fibers offer. An OSNR gain of 3.2, 4.1, 4.9, and 6.8 dB at the hard-decision forward error correcting limit with respect to single mode fiber back-to-back performance is shown for DP-OPSK, 8,16, and 32 DP-QAM~ respectively.
