TL;DR: EML-based IM/DD 4×112.5-Gbit/s PAM-4 transmission over 80km SSMF for inter-DCI applications is experimentally demonstrated thanks to the transmitter-side DSP based on linear pre-equalization and nonlinear look-up-table pre-distortion.
Abstract: We experimentally demonstrated EML-based IM/DD 4×112.5-Gbit/s PAM-4 transmission over 80km SSMF for inter-DCI applications. Thanks to the transmitter-side DSP based on linear pre-equalization and nonlinear look-up-table pre-distortion, the performances are significantly improved.

TL;DR: In this article, the authors demonstrate the generation and transmission of single-carrier 120-GBd electronic time-division multiplexing (ETDM) polarization division multiplexed 16-ary quadrature amplitude modulation (16 QAM) signals.
Abstract: We demonstrate the generation and wavelength-division multiplexing (WDM) transmission of single-carrier 120-GBd electronic time-division multiplexing (ETDM) polarization division multiplexed 16-ary quadrature amplitude modulation (16 QAM) optical signals. Both transmitter-side optical preemphasis and receiver-side maximum likelihood sequence estimation are utilized to mitigate the impairments caused by bandwidth limitation of the optoelectronic components. Thanks to the preemphasis and post equalization, we have successfully transmitted 12 WDM channels on 150-GHz grid, each loaded with 960-Gb/s (800 Gb/s data signals + 20% FEC emulated overhead bits) over 1200-km link based on 100 km/span TeraWave terrestrial optical fiber. The achieved data rate interface ensured spectral efficiency of 5.33 b/s/Hz. To the best of our knowledge, this is the first experiment with the highest symbol rate reported for ETDM-based 16 QAM signals.

TL;DR: In this article, a scheme for generating asymmetric single sideband photonic vector signal at millimeter wave spectral region is described, where information bits to be transmitted are modulated using a vector modulation technique to generate a baseband signal.
Abstract: A scheme for generating asymmetric single sideband photonic vector signal at millimeter wave spectral region is described. At a transmitter, information bits to be transmitted are modulated using a vector modulation technique to generate a baseband signal. The baseband signal is converted into its single sideband (SSB) version using a complex frequency source having a first frequency. The real part of the upconverted signal is added to the real part of a second frequency source and is input as I component to an I/Q modulator. The imaginary part of the upconverted signal is added to the imaginary part of the second frequency source and is used as the Q component. The I/Q modulator is driven by a laser source at frequency fc. The resulting signal is transmitter over an optical transmission medium and upconverted by a single-ended photodiode to a desired radio-frequency (RF) carrier frequency.
