107.1 and 93.9-Gbps net-rate (gross-rate 133.9 and 101.3-Gbps) OFDM transmission on a 408-GHz carrier frequency is experimentally demonstrated over a joint fibre-wireless link 51-km single-mode fibre and 10.7-m free-space with bit-error-rates below the 20% soft- and 7% hard-decision FEC thresholds of 2.7E-2 and 3.8E-3 respectively.
