Ok .. the installer has now drilled a hole into my premise/house/gaff ... what's going on from here ?

With all new installations of FTTH, the typical setup looks like this:

The cradle is called an ODP - it holds the fibre coming from the outside and feeds it into the ONT. That's the unit sitting in the cradle.

It is typically mounted at the nearest double socket from where the cable enters the premise. The installers are generally not allowed to run the cable through the attic or install the the equipment up there. But if you have installed ducting through the attic and fitted it with a pull rope, there is nothing preventing you from getting the cable routed through the attic.

On older installations the ONT and ODP are 2 seperate boxes mounted side-by-side.

From the ONT (Optical Network Termination), there is a Cat5e/Cat6 Gigabit connection to your router.

The fibre cable can be brought in a various of manors:
  • Overhead
    • OpenEIR: the last drop can be no more than 50m
    • SIRO: as ESB Networks has to be involved for overhead installs, it can take 4-6 weeks to complete the installation
  • Surface retractable
    • This is a SIRO only type install and requires drilling to get the fibre in, but is otherwise straight forward. It only applies in areas, where building owners have given SIRO permission to run the cabling on the surface of the building.
  • Underground
    • OpenEIR: the ducting guidelines can be found here. Any civils on your own premise (blocked ducting, collapsed ducting, no ducting) are your responsibility to fix.
    • SIRO: the cable is ran through the ESB ducting to your ESB meter. All civils needed up to that point are taken care of by SIRO. SIRO then brings it from there to the nearest double socket to mount the ODP and ONT. You can run your own Cat5e/Cat6 cable to bring the router to a different place in your house.
