QAM based coherent transmission technologies using DSP

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Recent progress on QAM coherent transmission is described. QAM transmission started at 20 Msymbol/s, 64-128 QAM, and recently reached 1 Gsymbol/s, 64 QAM, carrying 12 Gbit/s data in a 2 GHz optical bandwidth.
