105Tb/s transmission system using low-cost, MHz linewidth DFB lasers enabled by self-homodyne coherent detection and a 19-core fiber

摘要

We demonstrate a 105.1Tb/s self-homodyne transmission system using low-cost DFB lasers with dynamic path length adjustment and reduced DSP requirement in a 19-core-fiber with each signal core carrying 125×25Gbaud QPSK signals on a 50GHz grid.
