Giacomo Borraccini is a Postdoctoral Scientist in the Optical Networking and Sensing Department at NEC Laboratories America. He received his Master of Science in Electronic Engineering and his PhD in Electric, Electronic & Telecommunication Engineering from Politecnico di Torino. His research focuses on physical-layer fiber-optic networks, with an emphasis on system-level optical-transmission design, modelling, and control. At NEC, Dr. Borraccini contributes to the development of open and disaggregated optical network systems, spanning different scenarios and use cases.In an age defined by massive data consumption, the next generation of optical networks will target enhanced scalability to accommodate increasing capacity demands, ensuring rapid deployment and seamless integration. Targeting those challenges, he plays a key role in NEC’s collaborative efforts to define automatic procedures based on telemetry, incorporating automation and cognition into network management. His work includes automated physical-layer characterization and optimization of single- and multi-band amplified systems (both lumped and distributed) using analytical models, machine learning, and numerical optimization algorithms.
We proposed the use of BOTDA as a monitoring tool to identify fiber types present in deployed hybrid-span fiber cables, to assist in network planning, setting optimal launch powers, and selecting correct modulation formats.
We report the first field demonstration of 4D link tomography using a commercial transponder, which offers distance, time, frequency, and polarization-resolved monitoring. This scheme enables autonomous transponders that identify locations of multiple QoT degradation causes.
