52.1 Tb/s C-band DCI transmission over DCI distances at 52.1 Tb/s C-Band DCI Transmission over DCI Distances at 1.49 Tb/s/λ.49\ \text{Tb}/\mathrm{s}/\lambda$

We report on a DWDM DCI transmission system relying on highest per channel symbol rate of 1.49 Tb/s at 128 GBaud. We compare transmission over G.652 and G.654.E fiber and report a new capacity record of 52.1 Tb/s for C-band transmission.
