Open access broadband network provider Enet has launched Phase 1 of a multi duct & fibre corridor spanning more than 440km, connecting Dublin, Galway, Limerick and Cork and providing existing fibre and capacity products as well as a soon to be commissioned, new ultra-low latency fibre route for telecom operators and digital infrastructure providers across Ireland.

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 within the network.

The corridor runs from Ballycoolin in Dublin through Athlone to Galway, before continuing south through Shannon and Limerick to Cork, linking major regional hubs and digital infrastructure locations.

The route includes key interconnection points in Dublin, Athlone, Galway, Shannon and Limerick, supporting high-capacity transmission across the corridor and enabling connectivity between major urban centres and data centre locations.

The underlying infrastructure consists of multiple 25/20 subducts running along the full route, supporting scalable fibre deployment by multiple operators.

Designed as a high-speed, ultra-low latency fibre route, the network supports high-capacity optical transmission with regeneration capability along the corridor, enabling long-distance transmission while maintaining performance.

Phase 1 of the network forms part of Enet’s wider national ring network initiative, which will represent a combined investment of approximately €100 million once all phases are complete. The project forms part of Enet’s broader strategy to expand open access fibre infrastructure across Ireland, supporting growing demand driven by cloud services, data centre connectivity, sub-sea interconnects and increasing network traffic.

Peter McCarthy, CEO of Speed Fibre Group (pictured), said: “Demand for fibre infrastructure continues to grow as telecom operators, data centre providers and international carriers expand capacity across Ireland. By opening this network on an open access basis, we are enabling operators to deploy fibre infrastructure more efficiently while strengthening connectivity between Ireland’s major regional hubs.”
