The IONIAN submarine cable system is a 320km repeaterless submarine cable connecting Crotone, Italy, with Preveza, Greece.

The IONIAN submarine infrastructure is complemented by two terrestrial fibre rings connecting the system to the cities of Milan and Rome in Italy and Athens and Thessaloniki in Greece.

IONIAN offers wholesale capacity, optical spectrum and dark fibre to telecommunication operators and content providers.

The IONIAN submarine cable system is jointly developed and owned by IslaLink and Elettra, a fully owned subsidiary of Orange.

Headquartered in Madrid, Spain, IslaLink is an independent and neutral telecommunications operator specialized in submarine fiber-optic systems and related activities. IslaLink is now owned by Fiera Infrastructure, a leading investor across all subsectors of the infrastructure asset class. Fiera Infrastructure acquired 100% of IslaLink in July 2018.
