Abstract :
Multiple-input multiple-output (MIMO) systems can be observed in a huge variety of transmission links and network parts and have attracted a lot of attention since the mid 90´s. In the field of optical MIMO transmission systems, multi-mode (MM) fibre offers the possibility to transmit different signals by different mode groups. In order to investigate the perspective of the MIMO philosophy within the field of optical transmission systems, channel measurements within a (2 × 2) MIMO system are carried out. For the channel measurements the second optical window and a fibre length of 1, 4 km was chosen. Computer simulations on an overall data rate of 10, 24 Gbps underline the potential of multi-mode fibres in optical high-data rate MIMO communication systems and show that in order to achieve the best bit-error rate, not necessarily all MIMO layers have to be activated.
