How fibre optic connections work
Fibre optic (fibre optic) broadband differs from ADSL broadband in one key area. Whereas ADSL relies on running over copper telephone wires, fibre optic works via running over cables that are in the ground.
Either glass or plastic is used as a material for fibre optic cables, which helps data to be moved along their length very quickly. A disadvantage of ADSL broadband, by comparison, is that speed can quickly decrease when great distances are involved. How far in terms of distance the homes are from the exchange impacts on speed, and causes variation.
Not all that much speed is lost over great distances with a fibre optic connection. In terms of superfast broadband, fibre optic is a better option than ADSL.

The company's 360Mb service is widely available and if you're in a large town or city, there's a very, very good chance you'll be able to get it.

eir also offers a fibre broadband service, which as they supply through the phone lines. eir is currently updating their connections by installing fibre-to-the-cabinet cabling infrastructure. This means that many customers who are receiving up to 24Mbps ADSL broadband via their phone lines, should soon be able to access up to 100Mbps from the same lines.
