Samenvatting
Achievable information rates (AIRs) of wideband optical communication systems using a ∼40 nm (∼5 THz)
∼40 nm (∼5 THz)
erbium-doped fiber amplifier and ∼100 nm (∼12.5 THz)
∼100 nm (∼12.5 THz)
distributed Raman amplification are estimated based on a first-order perturbation analysis. The AIRs of each individual channel have been evaluated for DP-64QAM, DP-256QAM, and DP-1024QAM modulation formats. The impact of full-field nonlinear compensation (FF-NLC) and probabilistically shaped constellations using a Maxwell–Boltzmann distribution were studied and compared to electronic dispersion compensation. It has been found that a probabilistically shaped DP-1024QAM constellation, combined with FF-NLC, yields achievable information rates of ∼75 Tbit/s
∼75 Tbit/s
for the EDFA scheme and ∼223 Tbit/s
∼223 Tbit/s
for the Raman amplification scheme over a 2000 km standard single-mode fiber transmission.
