We report the experimental measurement of 112 Gb/s transmission back-to-back and through 12 km of S-SMF with a single directly-modulated laser (DML) using the novel modulation format Orthogonal PAM-DMT. This work demonstrates a record DML-based 112 Gb/s receiver sensitivity of -7.1 dBm at a BER of 10(-3), outperforming conventional PAM and DMT by approximately 2.5 dB.
