It is a place where all the fiber optic lines of subscribers from the same district or the same city converge and this is where they are connected to the national network. For each premises, there can be up to several tens of thousands of lines, which can be activated or deactivated. There are also subscriber connection nodes, or NRAs, which are designed for ADSL and telephone lines.

This is a room in which there is an inverter and backup batteries (to prevent power cuts), air conditioning (to maintain a constant temperature and cool the machines), lots of cables distributed throughout the rooms. directions and optical network switches, or “ optical switches »: these are devices that create virtual circuits between several devices.

Free has its own NROs, although it sometimes rents premises in . But for Very Dense Areas (ZTD) like Paris or the rest of Île-de-, it has its NROs. Downstream of the NROs, we find the famous metal cabinets that we see in the streets, called optical pooling points (PM). They are the ones connected to the NROs and who ultimately distribute your fiber lines. In some cases, a connection node can also be a pooling point.
