Field trial of 24-Tb/s (60 × 400Gb/s) DWDM transmission over a 1910-km G.654.E fiber link with 6-THz-bandwidth C-band EDFAs

We demonstrate real-time 24-Tb/s dense wavelength division multiplexing (DWDM) transmission over a 1910-km field-deployed G.654.E fiber link using 24 in-line wide-bandwidth Erbium-doped fiber amplifiers with a widened bandwidth of 6 THz in the cost-effective C-band. The DWDM system consists of 60 10...

Zusammenfassung:We demonstrate real-time 24-Tb/s dense wavelength division multiplexing (DWDM) transmission over a 1910-km field-deployed G.654.E fiber link using 24 in-line wide-bandwidth Erbium-doped fiber amplifiers with a widened bandwidth of 6 THz in the cost-effective C-band. The DWDM system consists of 60 100-GHz-spaced 400-Gb/s wavelength channels, modulated with probabilistic constellation shaped polarization-division-multiplexed 16-point quadrature-amplitude modulation and fast-than-Nyquist shaping. This field trial shows the feasibility of achieving a record per-fiber capacity of 24 Tb/s in field-deployed 2000-km-class terrestrial fiber links by using the widened C-band.
