The transit network comprises rings of backbone fibre-optic cables that will connect NBN Co’s central hub to the modern equivalent of telephone exchanges.
Construction of the transit network is an important component of NBN Co’s plans to provide a connection within the reach of every Australian household and business to its fibre, fixed wireless or satellite services.
NBN Co Head of Construction Dan Flemming said “The transit network will allow NBN Co to connect the different fibre access nodes to points where the traffic will be transferred to service providers.”
In the first stage of the build, NBN Co plans to construct 149 transit links connecting 168 fibre access nodes, of which 30 are also points of interconnect (PoI).
The overall project, involving 121 PoI, is targeted for completion over the next three years, at which point the network management layer back to the Network Service Operation Centre is also expected to be completed.
