Abstract
We report the first terabit/s superchannel transmission over a submarine distance >10,000 km. Four 1.15-Tb/s superchannels, each consisting of 23 optical subcarriers at 12.5-GHz spacing are modulated with DP-QPSK at 12.5 Gbaud. The WDM signal is transmitted over 168×60.6-km spans of hybrid large-core/ultra low-loss fibers with inline amplification by low noise C-band EDFAs. The system achieved a Q-factor margin of 2 dB assuming the use of HDFEC, and a spectral efficiency of 3.6 b/s/Hz is achieved.
