16 QAM
15 February 2011
We report a 5x448-Gb/s 16-QAM transmission system with 2 optical carriers at 40-GHz separation (4-bit/s/Hz spectral efficiency) optimized for 100-GHz ROADM application. We demonstrate successful transmission over a full EDFA amplified 6x80-km SMF transmission link. 2010 Optical Society of America
