Creating and sharing knowledge for telecommunications

Project: High-capacity optical transmission infrastructure to support 5G communications and beyond

Acronym: Opt5G+
Main Objective:
At the technical level, the main objectives of the Opt5G+ project are summarized in the following:
- development, implementation and prototyping of a highly-spectral efficiency transceiver for high-capacity fiber-based optical fronthauling;
- development and experimental validation of machine-learning algorithms for the mitigation of nonlinear phenomena associated realistic optical transceivers;
- development, implementation and prototyping of an advanced free-space optics transmission link for ultra-high-capacity wireless backhauling.
