IRIS is a new high-speed undersea cable system, spans approximately 1,700 km in length and connects south west of Iceland to Ballyloughane Strand in Galway, Ireland.

The IRIS cable system is designed with a six-fiber pair trunk for a total system capacity of 132 Tbps, or 22Tbps per fiber pair.

The IRIS cable system is privately owned and operated by Farice. Farice is fully owned by the Icelandic Government and plays an important role in Iceland's infrastructure for the greater public good and economic life in Iceland. In additional to the new IRIS cable system, Farice owns and operates another two submarine systems connecting Iceland to Europe, FARICE-1 and DANICE.

The IRIS cable system is supplied by SubCom.

SubCom announced contract-in-force for the IRIS cable system in April 2021, and achieved provisional acceptance and system handover on November 11th 2022.

The IRIS cable system was ready for service on March 1, 2023.
