Taking long repeatered submarine systems to 40Gbit/s and beyond
repeatered submarine systems beyond
2015/7/20
We review recent advances in experimental demonstrations of transmission at 40Gbit/s and 100Gbit/s per channel over submarine distances. Coherent detection, large effective area fibers, and hybrid amp...
Experimental Demonstration of Optical Colorless Direct-Detection OFDM Signals with 16- and 64-QAM Formats beyond 15 Gb/s
Optical Colorless Direct-Detection OFDM Signals Formats beyond
2015/7/30
Both highly spectral-efficient direct-detection 15-Gb/s 64-QAM and 20-Gb/s 16-QAM OFDM signals are demonstrated. Negligible penalty is observed following 25-km SMF transmission.
