Fiber optic deployment, how does fiber work?
The deployment of optical fiber today
To connect a home to optical fiber, you have to go through two steps of fiber optic deployment. The first is to bring the optical fiber to a building or an optical connection node, in the case of a house. The second is to deploy the fiber to the housing. These two steps allow you to understand how optical fiber works and how to benefit from it at home.
In addition, with a view to covering the entire territory with optical fiber and connecting almost all French households to very high speed (THD), the State has launched since 2013, the Plan France Très Haut Débit, which aims to extend fiber optic coverage to the entire metropolitan area by 2023.
Fiber deployment up to NRO
Before you can connect a building or a house to optical fiber, the optical fiber must first be deployed to the Optical Connection Node . This is the place where the lines of subscribers from the same district or city converge. It is comparable to the NRA for telephone and ADSL lines.
Thus, in the same way as a telephone exchange where the copper pairs of the switched network (PSTN) and ADSL equipment (DSLAM) are centralized, the NRO groups together the fiber optic cables deployed by Orange and the optical line terminal ( OLT). Unlike NRAs, all NROs are owned by Orange . The other operators also set up their own NROs, and each operator can lease an NRO slot to the others.
The OLT is the only active equipment which forms the junction between the local distribution network (allowing the connection of housing) and the national optical collection network.

To connect a building to optical fiber , you must have the approval of the condominium manager. This kind of decision is taken during the general meeting of co-owners which usually takes place once a year. When the decision is made, an agreement is signed with an operator. It is he who installs the fiber in the first place in the building. It will, via pooling points connected to the optical connection points , deploy the fiber in the common areas vertically. It will offer the inhabitants of the building the installation of optical terminal sockets allowing them to connect their homes. The operator who has deployed the fiber then has a temporary monopoly.
To benefit from the Internet by optical fiber, it is necessary to have an optical socket installed in your home by a technician.
