Journal ArticleDOI
The GN-Model of Fiber Non-Linear Propagation and its Applications
TL;DR: This paper tries to gather the recent results regarding the Gaussian-noise model definition, understanding, relations versus other models, validation, limitations, closed form solutions, approximations and, in general, its applications and implications in link analysis and optimization, also within a network environment.
Journal ArticleDOI
On the Performance of Nyquist-WDM Terabit Superchannels Based on PM-BPSK, PM-QPSK, PM-8QAM or PM-16QAM Subcarriers
TL;DR: In this article, the performance of Nyquist-WDM Terabit superchannels implemented using polarization-multiplexed phase shift-keying based on 2 (PM-BPSK) and 4 (PM)-QPSK signal points was investigated through simulations.
Journal ArticleDOI
Modeling of the Impact of Nonlinear Propagation Effects in Uncompensated Optical Coherent Transmission Links
TL;DR: In this paper, perturbative models for the impact of nonlinear propagation in uncompensated links were proposed and analyzed for a set of formats including PM-BPSK, PM-QPSK and PM-8QAM.
Journal ArticleDOI
EGN model of non-linear fiber propagation
TL;DR: This paper analyzes in detail the GN-model errors and derives a complete set of formulas accounting for all single, cross, and multi-channel effects that constitute the enhanced GN- model (EGN-model), which is found to be very good when assessing detailed span-by-span NLI accumulation and excellent when estimating realistic system maximum reach.
Journal ArticleDOI
Performance Limits of Nyquist-WDM and CO-OFDM in High-Speed PM-QPSK Systems
TL;DR: The two techniques for generating polarization-multiplexed quadrature phase-shift keying with a high spectral efficiency have the same sensitivity and SE under idealized assumptions, but it is found that CO-OFDM requires a much larger receiver bandwidth and proportionally faster speed of the analog-to-digital converters.
