In this paper, we evaluate the performance of hybrid differential phase shift keying-
multipulse pulse position modulation (DPSK-MPPM) techniques in long-haul nonlinear …

A hybrid optical modulation approach is described, which layers a continuous wave MM–ary
differential phase-shift keying (M\rmDPSK MDPSK) and a two-level (2L 2 L) multipulse pulse …

Ultra-low loss (ULL) fibers are being widely deployed in optical networks due to their high
transmission capacities. Existing studies on ULL fiber deployment have assumed to …

We present a self-configured and unified access and metro network architecture, named
ARMONIA. The ARMONIA network monitors its status, and dynamically (re-) optimizes its …

In this paper, we modify the Gaussian noise model (GN-model) to address the nonlinearity
effects in few-mode fibers. Closed-form expressions for the nonlinear interference power in …

We propose a fast analytical model to evaluate fiber nonlinear noise variance for real-time
planning of mesh optical networks. This model is based on an incoherent Gaussian noise …

We propose a fast quality of transmission (QoT) estimation method based on cascaded
artificial neural networks (ANNs) for intensity modulation-direct detection (IMDD) systems …

We review the fundamentals of the recently proposed Constant Power Spectral Density
(CPSD) model for very long-haul space-division multiplexed submarine links, and highlight …

We propose a propagation model for the weakly coupled multicore fiber (MCF), taking into
account crosstalk random behavior with respect to both frequency and spatial distribution …

Machine learning has been introduced to estimate the quality of transmission (QoT) of
lightpaths to meet the reliability of optical network transmission. In the early deployment …
