A fibre optic node is a concentration point in an optical fibre network. The active equipment from which the operator activates its subscribers’ accesses is installed there. To protect this equipment from harsh external factors, Grolleau offers prefabricated shelters that provide security and stability:
- Light-weight shelters made of double-skin insulated aluminium from 5 to 20 M 2
- Heavy-weight shelters made of concrete, prefabricated in our plant, from 5 to 20 M2
This allows for connections from 1,000 to 4,000 subscribers. The plant rooms are made up of large shelters upstream of the shared access points (SAP cabinets), located within the city.
However, the fibre optic node shelters generally have at least two distinct spaces:
- a first space for hosting service operators (bays housing active equipment, LVGS (Low Voltage General Switchboard), air conditioning, supervision and alarm systems, etc.);
- a second space for the bays or trusses housing the cable heads of the FTTH (Fibre to the home) service network.
