Currently discussed solutions for 80 km DWDM transmission targeting inter-data center
connections at 100G and 400G line rates are reviewed. PDM-64QAM, PAM4, and discrete …

We report on the results of a field trial carried out on a Telecom Italia metro link, targeting
short data center interconnect applications. The test-bed presented realistic transmission …

Power-digital-to-analog converters (DAC) circuits for high capacity and high spectral
efficiency optical transmitters are presented in this paper. They are based on a 0.7-μm InP …

Computational applications are subject to various kinds of numerical errors, ranging from
deterministic roundoff errors to soft errors caused by non-deterministic bit flips, which do not …

We demonstrate fully blind processing and reduced-complexity nonlinear equalization
(NLE) of a 100G PM-64QAM optical channel in a 50 GHz WDM grid, achieving a maximum …

Since the advent of wavelength division multiplexed optical systems, increasing the bit rate
per optical carrier has proved to be the most effective method to drive the overall cost of …

We demonstrated the transmission of a Nyquist-WDM signal based on PM-64QAM
modulation in an EDFA-only submarine configuration composed of 54.4 km-long fiber …

Increasing the symbol rate (or baudrate) has been considered inevitable for increasing the
interface rate as well as reducing the cost per bit of the next generation fiber optical …
