In 2019, the West coast of Ireland and Galway was designated as a landing location for international telecommunications cables with increased availability of terrestrial networks across the country enabling this. This modern high-capacity telecom cable will connect Galway to Iceland, the presence of the Farice system landing in Galway will provide direct high-capacity links to Iceland but also to Northern Europe via Denmark and will greatly increase capacity and connectivity in the Galway region.

Farice signed a contract with SubCom to install the IRIS Cable System and SubCom has now received provisional acceptance for the IRIS Cable System, the final phase before officially handing the system over to its owner, Farice.

The IRIS Cable System will be ready for service in the first quarter of 2023 and will be the third submarine fiber optic cable system connecting Iceland with Europe.

Delivering a system capacity of 108 Tbps on 6 fiber pairs, the IRIS Cable System provides further redundancy in telecommunication connection between Iceland and Europe, with low latency connections around 10.5 ms, between Reykjavík and Dublin. The IRIS Cable System is integrated into Farice’s network in Iceland and Europe to enhance the network and provide comprehensive, diverse, and secure connectivity between Farice’s network POPs in Iceland and Europe.
