We investigate the impact of stimulated Raman scattering (SRS) in multi-band transmissions. We first derive and test against numerical results an extended Christodoulides-Zirngibl (ECZ) SRS model b…
We study the technical viability of Multi-core and Hollow-core fibers for submarine links considering transceiver limitations and typical power constraints of Spatial Division Multiplexed systems. …
Having in mind the capacity optimization of power-constrained submarine links, by following the work in (Cho et al. , 2020) we first compare the achievable information rate (AIR) of gain-flattened …
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 its use for Erbium-dope…
In this paper, we propose a novel technique to estimate the polarization-dependent loss (PDL) of reconfigurable optical add-drop multiplexers (ROADMs) in a terrestrial optical network. The idea is …
We consider the capacity optimization of submarine links when including a realistic model of the constant-pump erbium doped fiber amplifiers (EDFA) with gain-shaping filters (GSF). While Perin et a…
We present a theoretical model that fully supports the recently disclosed generalized droop formula (GDF) for calculating the signal-to-noise ratio (SNR) of constant-output power (COP) amplified co…
