This paper describes the transmission of a non-guard interval 1.12 Tb/s 10-carrier superchannel, launched into a 226 km recirculating loop. After two round trips (452 km) a BER below the FEC limit (3.8 x 10-3) was still obtained. To evaluate the superchannel generation technique, up to 72 comb lines (OSNRmin = 12.7 dB) were generated and modulated (DP-QPSK) at 112.5 Gb/s and, in a back-to-back configuration, such an 8.06 Tb/s signal was detected by a coherent receiver with offline processing, resulting in a maximum BER of 2.4 x 10-3.
