Transmission of 200Gb/s PM-16QAM and 150Gb/s PM-8QAM DWDM Signals over Long-haul and Transoceanic Distance at 100km Span Length with EDFA-only

We demonstrate transmission of 78×256Gb/s PM-16QAM over 4800km, and 78×192Gb/s PDM-8QAM over 7200km with 100km span length at spectral-efficiency 6.0 and 4.5 b/Hz/s, respectively. This is achieved by ultra-large-A eff ultra-low-loss fibre using EDFA-only for amplification.
