We review the most recent advanced concepts and methods employed in the cutting-edge
spectrally efficient coherent fiber-optic transoceanic transmission systems, such as …

We investigated the reach increase obtained through nonlinearity mitigation by means of
transmission symbol rate optimization (SRO). First, we did this theoretically and simulatively …

We investigate upper bounds for single-channel and multi-channel digital back-propagation
(BP) in fully loaded wavelength-division multiplexed systems. Using the time-domain model …

A general theory of nonlinear interactions between signal and amplified spontaneous
emission noise in wavelength division multiplexed fiber-optic coherent transmission systems …

Methods and systems for reach extension of multi-carrier channels using unequal subcarrier
spacing may decrease FWM by grou** the subcarriers into groups of 2 subcar riers, and …

Based on state-of-the-art transmitter technology we investigated symbol-rate (up to 64Gbd)
and constellation size (up to 64QAM) dependencies on the linear and nonlinear …

Maximizing the delivered capacity of optical transponders by mining the SNR margin to a
near-zero level is of critical importance for the economic viability of future optical networks …

Real-time, error-free 16QAM transmission at a record spectral efficiency of 6.21 b/s/Hz
enables transatlantic (6,644 km) fiber capacity of 26.2 Tbps, using precision, multi-carrier …

The fundamental penalty of subcarrier modulation (SCM) with independent subcarrier phase
noise processing is estimated. It is shown that the fundamental signal-to-noise ratio (SNR) …
