Why is SIRO different?

SIRO’s key innovation is that it is a 100% fibre-optic internet connection all the way to the building (fibre-to-the-building), making it a vast improvement on any other broadband infrastructure currently available in Ireland, with no copper connection at any point in the network. SIRO is Fibre-to-the-building which means you’ll have incredible speed and reliability instantly.

How is SIRO installed?

When you purchase SIRO from a broadband provider, an engineer will visit your home at a time agreed by you to complete the fibre first installation. SIRO will be brought into your home either overhead or underground and into the ESB meter box. An external connector box which houses the SIRO fibre will be positioned close to the ESB meter box.

The engineer will agree with you where to install our internal connector box. Some minor drilling is involved and some cabling depending on where you would like your modem. The engineer will ensure and prove that your home is receiving the fibre first speed based on the package purchased.

For SME and Enterprise customers, an engineer will work with the business to determine the entry point. Where applicable the existing communications space will be utilised.

What is SIRO?

SIRO is a joint venture company between the ESB and Vodafone. We are building a 100% fibre-to-the-premise broadband network using the existing ESB infrastructure.  Launched in 2015, SIRO is Ireland’s first 100% Fibre First wholesale network and offer speeds of up to 2 Gigabit, the fastest speeds available on the market.

Why did ESB & Vodafone get involved?

SIRO was launched in 2015 with our shareholders ESB and Vodafone committing €450m to connect the first 50 towns.  The two shareholders have complementary skill sets. ESB was a pioneer in electrifying Ireland and have unparalleled knowledge of large-scale engineering projects. Vodafone is Ireland’s leading mobile telecoms operator, with over a million customers and world-leading expertise in the transmission of data. These two companies enable SIRO to build a regional 100% fibre-to-the-building network, the first of its kind in Ireland. In 2021, we have received further investment of €620m into the expansion of our network to 770k homes and businesses across 154 towns.
