214-Tb/s Transmission over 2×75-km in the S+C+L Band with >1-Tb/s/λ Signals Using Only Doped Fiber Amplifiers

We demonstrate a $214-\mathrm{Tb} / \mathrm{s} \mathrm{S}+\mathrm{C}+\mathrm{L}$ band optical signal over $2 \times 75-\mathrm{km}$ G. 654 transmission in an 18.7-THz bandwidth using only DFAs. The net bit rate per wavelength exceeds $1 \mathrm{~Tb} / \mathrm{s}$ for each of the 204 channels.
