Alexis Carbo Meseguer | Researcher
Alcatel Submarine Networks

Alexis Carbó Meseguer joined ASN in 2018. Since then, he has worked on the modeling and characterization of new subsea Open Cable systems. Among other topics, he has studied the impact of signal droop, GAWBS, and EEPN. He also proposed a novel experimental model to analyze both the homogeneous and inhomogeneous responses of EDFAs. In parallel, he pioneered the development of an automation technique to reduce the time required for Subsea Open Cable commissioning—an essential step for major submarine cable deployments. In 2022, he was recognized as a DMTS by Nokia for his outstanding technical contributions to their Network Infrastructure division. Back when humans could still submit post-deadline papers, he had the chance to co-author two with Nokia Bell Labs. We demonstrated the first 100 nm continuous-band lumped-amplified transmission system based on novel ultra-wideband semiconductor optical amplifiers. This system enabled the successful transmission of 116 Tbps using 250 channels, each carrying over 400 Gb/s, over a 100-km link (PDP ECOC 2017). We also demonstrated 65 Tbps transmission over 6600 km, using for the first time a probabilistically-shaped constellation combined with SC-LDPC FEC codes (PDP ECOC 2016).
