50-Gb/S Dispersion-Unmanaged DMT Transmission with Injection Locked L0G-Class L.55-μm DML

We demonstrate 50-Gb/s DMT signal transmission over 20-km SMF by using a 10G-class 1.55-μm DML without optical dispersion compensation. Injection locking technique is introduced, which doubles system bandwidth and greatly suppresses DML chirp.
