What is SIRO?

SIRO is broadband at the speed of light.

How does it work? SIRO is the only network in Ireland with 100% fibre optic cables that use light to transfer data. This enables SIRO to deliver up to 1,000 Megabits (or 1 Gigabit) per second broadband straight into your home or business.

SIRO’s technology is the first of its kind in Ireland. It is the only technology licensed to use ESB’s existing infrastructure. As a result, it is up to four times faster than the max broadband speeds available in cities and ten times that in rural areas.

Connecting 500,000 homes and businesses in over 50 regional towns, SIRO is and will be a vast improvement. With other networks, a high definition film of 4 gigabytes can take up to one hour to download. With SIRO, it takes 30 seconds.
