Access Fibre Modular Configuration


Fibre Structure—Underground

The configuration for underground local fibre is shown below, where the local access joint is used to provide the multiport tethers from a central pit, feeding pits located at the property boundary and multiport terminals utilised to provide the ‘plug and play’

connections .

For planning purposes a rectilinear estimation of a Fibre Serving Area can be generated to provide an estimated distance of distribution fibre. Note that the fibre cable may contain tubes for local, distribution & trunk fibres.

Planned Transit Network


The Government has opted for a semi-distributed POI model

“The Government has determined that a semi-distributed POI structure which extends the NBN Co network to meet with, but not overbuild competitive backhaul routes is the preferred outcome.” – Statement of Expectations to NBN Co, 17 December 2010.

The ACCC has published a draft list of 121 POIs that meet the competition criteria – being 80 metropolitan locations and 41 regional locations.

NBN Co is currently conducting detailed design of the nominated POIs.

FTTP Brownfield's Activity Profile (as at 25-Oct-12)


FSAM Sequence GeneratorPolicy Rules• Coverage of both rural & metro• Coverage in all States & Territories• Provide all of Tasmania by 2015• Fixed Wireless complete by mid 2015• All New Developments (over 100 premises)

Practical Rules• All Transit Network completed by 2015.• Level Regional Construction Packages (RCP)• Full FSA is built once started.• All FSAs are built on a Transmission Ring.• FSAs containing New Development premises are given priority.

• Adjacent FSAs are built as a higher priority.• In Metropolitan areas, FSAs are built outwards from the Aggregation Nodes.

Strategic Rules• Prioritisation of locations that contain Universities associated with the First Release Sites that have committed Broadband programs.

• Transit connectivity for First release sites, Second release sites and the New Developments to be provided first.
