HydRON status: the European Space Agency’s optical network beyond the clouds

The European Space Agency's High Throughput Optical Network (HydRON) project envisions a future where terrestrial high-capacity networks seamlessly extend into space, creating an "Internet beyond the cloud(s)". This initiative seeks to integrate space assets with terrestrial fibre networks, ultimately establishing a robust, multi-dimensional optical network, spanning across various orbital and atmospheric layers all the way to the bottom of the sea. The HydRON-Demonstration System (DS) is designed to progressively validate the key technologies required for a first all-optical transport network operating at terabit-per-second capacities. This paper provides a timely update on the current status of the project, highlighting advancements since its inception. The vision of a truly networked space, providing capabilities akin to terrestrial fiber networks, is swiftly moving towards realization through a series of strategic implementation phases.
