Single-Wavelength Net 1 Tb/s Transmission in SMF and 6.4 Tb/s in Weakly-Coupled 7-Core MCF Using a Phase- and Polarization-Diverse Direct Detection Receiver in Jones space

We demonstrate a record single-wavelength net 1.04-Tb/s transmission over 40-km SMF using 56.5-GHz Jones-space direct-detection receiver with the highest electrical spectral efficiency of 18.4 b/s/Hz. Using the 42-km weakly-coupled 7-core multi-core fiber, we achieve a net 6.49-Tb/s signal transmission for large-scale and high-capacity data center interconnects.
