DCI Field Trial Demonstrating 1.3-Tb/s Single-Channel and 50.8-Tb/s WDM Transmission Capacity

We demonstrate, to the best of our knowledge, the highest reported single- and multi-channel capacities over a field-deployed data center interconnection (DCI) system operating over 93 km of standard single-mode fiber using only Erbium-doped fiber amplification. Using off-the-shelf hardware components, and in particular using only a single digital-to-analog converter per complex signal dimension, we achieve a net bit rate of 1.3 Tb/s per wavelength (single-channel operation) and more than 1.25 Tb/s per channel in a 40-channel wavelength-division multiplexed (WDM) system with a spectral efficiency of 11.29 bits/s/Hz. We achieve a total WDM capacity of 50.8 Tb/s across the C-band.
