Driver-Free Net-422-Gbps/λ PAM transmission based on TFLN Modulator, Advanced DSP and single DAC with the Highest Net Information Rate in 400G/λ IM/DD
2023 21st International Conference on Optical Communications and …, 2023•ieeexplore.ieee.org
… In this paper, we report single-lane 128-GBaud PAM-20 IM/DD transmission over 0.5-km
SSMF in C-band using only a single DAC and a TFLN-MZM with 3-dB bandwidth (BW) of 60-GHz.
We achieve net bitrates up to 425 Gbps for singlecarrier optical back-to-back (B2B), and net
422 Gbps after transmission over 0.5-km SSMF with 128-Gbaud PAM-20 signals.
Distinguished from all the recent benchmarks illustrated in Fig. 1, it is imperative to
emphasize that this work signifies the inaugural achievement of ultrahigh-order … Finally …

We report ultrahigh-speed transmission of net-422-Gbps/λ PAM-20 signals over 0.5-km SSMF in C-band, based on only one-DAC without any electrical amplifications, achieving a record net information rate (bits/symbol) in 400G/λ IM/DD.
