Leaked NBN document reveals low cost FTTP trial

Mar 03, 2016

A newly leaked document on the National Broadband Network has revealed that nbn (the company) has trialled a low cost fibre-to-the-premise (FTTP) solution.

The document – which Shadow Minister for Communications, Jason Clare, published online today – discusses a multi-technology local fibre network (MT-LFN) versus the current local fibre network.

This solution is argued to reduce the cost and time to build. Type 2 FTTP (fibre-to-the-premise) architecture was compared against MT-LFN in Ballarat and Karingal, Victoria. MT-LFN infrastructure is estimated to cost about $600 less per premise to build than Type 2 FTTP, according to design trial results.

nbn aims to reduce the cable size and minimise duct congestion and augmentation. It also wants to reduce the size and quantity of closure so that it minimises pit congestion. Single fibres instead of ribbon fibre will reduce the size of cables, nbn stated in its document.

Flexibility joint location, where there’s optical connectivity between the DFN (distribution fibre network) and LFN (local fibre network) fibres, is also part of the make-up of MT-LFN. This includes small footprint multi-ports connected via single fibre cables to a splitter.

nbn is looking to test this solution for greenfields single dwelling units and multi dwelling units, as well as combine with fibre-to-the-distribution-point (FTTdp).

Clare said in a statement that this leaked document – along with another released earlier this week which confirmed the NBN is delayed and over budget – shows that PM Malcolm Turnbull is playing politics rather than just getting on with connecting Australians to the initial FTTP NBN.

“In areas where Malcolm Turnbull’s second rate NBN has been switched on, complaints are flooding in that internet speeds on the second rate network are patchy and in some cases, even worse than ADSL.

“To add to this chaos, good people from inside NBN Co [nbn] are frustrated that they are being forced to construct a second rate network and consequently leaks are coming thick and fast,” he said.
