“…4), at a higher operating wavelength, i. e. 1570 nm, the separation of the different mode groups disappears based on the effect of the chromatic dispersion. Since the chromatic dispersion affects all mode groups almost equally, MIMO isn't able to generate an additional diversity gain (in comparison to wireless channels, where delayspread isn't any longer a limiting parameter (Ahrens and Benavente-Peces, 2009b;Ahrens and Benavente-Peces, 2011)). The advantage of a higher signal-tonoise-ratio due to lower attenuation in the third optical window is diminished by the chromatic dispersion.…”

In this contribution a coherent (2 × 2) MIMO (multiple input multiple output) transmission with iterative detection over a measured multimode fiber channel at 1325 nm as well as at 1570 nm operating wavelength is studied. For the channel measurements a fibre length of 1,4 km were chosen. Extrinsic information transfer (EXIT) charts are used for analyzing and optimizing the convergence behaviour of the iterative demapping and decoding. Our results show that in order to achieve the best bit-error rate, not necessarily all MIMO layers have to be activated.

In this contribution a coherent (2×2) (multiple input multiple output) MIMO transmission with iterative detection over a measured multimode fiber channel is studied. Extrinsic information transfer (EXIT) charts are used for analyzing and optimizing the convergence behaviour of the iterative demapping and decoding. The results show BER and energy-per-bit improvements when using optimized MIMO transmission as compared to conventional (single input single output) SISO transmission techniques.
