Enet has launched Phase 1 of a 440km multi-duct fibre corridor connecting Dublin, Galway, Limerick and Cork. The open access network provides high-speed fibre and ultra-low latency routes, with a total investment of approximately €100 million planned across all phases to support cloud services and data centre connectivity.
Enet, Ireland's largest open access network provider, has launched Phase 1 of a multi-duct and fibre corridor spanning more than 440 kilometres connecting Dublin, Galway, Limerick, and Cork, according to an official announcement. The network combines high-speed fibre infrastructure with open access duct capacity, enabling carriers and infrastructure providers to deploy fibre along the route or access dark fibre capacity. The corridor runs from Ballycoolin in Dublin through Athlone to Galway, then south through Shannon and Limerick to Cork.
Enet is an open access network provider operating fibre infrastructure across Ireland. The route includes key interconnection points in Dublin, Athlone, Galway, Shannon, and Limerick, supporting high-capacity transmission between major urban centres and data centre locations. The infrastructure consists of multiple 25/20 subducts along the full route, supporting scalable fibre deployment by multiple operators.
This development matters for Ireland's digital infrastructure sector, where demand for fibre is growing from telecom operators, data centre providers, and international carriers expanding capacity. The open access model enables operators to deploy fibre infrastructure more efficiently while strengthening connectivity between regional hubs. Phase 1 forms part of Enet's wider national ring network initiative, representing a combined investment of approximately €100 million once all phases are complete.
For the telecommunications industry, the corridor supports high-capacity optical transmission with regeneration capability along the route, enabling long-distance transmission while maintaining performance. Stakeholders including cloud service providers, data centre operators, and sub-sea cable carriers stand to benefit from expanded connectivity options and an upcoming ultra-low latency fibre route.
