NBN Co hits 105Mbps in limited FTTN trial

105Mbps down and 45Mbps up for one shop 100 metres from node

NBN Co achieved 105 megabits per second download speeds in a of test of fibre-to-the-node (FTTN) technology at a shop on the New South Wales Central Coast.

The test at the single premise in Umina achieved upload speeds of 45Mbps.

Engineers installed a VDSL modem in the shopfront and connected the existing copper telephone line to a node cabinet in the street about 100 metres away. The node cabinet converted the signal from the copper into pulses of light to travel over optical fibres.

The test was part of an FTTN pilot taking place in Umina and Epping in Melbourne’s northern suburbs. NBN Co is testing FTTN as one of a number of technologies to be used in its new mixed technology approach to the National Broadband Network.

Last week, the Coalition government officially signed the death warrant for the previous plan by Labor to roll out fibre to the premise to most homes and businesses.

NBN Co has been instructed to alter the network's rollout to employ a mix of technologies, including FTTN, limited FTTP, and HFC.

“Once active, the next step will see NBN Co invite retail service providers to take part in a limited FTTN end user trial in these locations,” said NBN Co chief operating officer, Greg Adcock.

“The aim will be to test the delivery and end user experience of high speed broadband via FTTN to a small number of premises at each location.”

NBN Co CEO Bill Morrow said the test was a key milestone for the NBN. “It demonstrates that existing technologies such as the copper network are capable of playing a vital role in delivering high speed broadband to Australians,” he said.

So much for the promise before the election that areas already earmarked to receive FTTP will still receive this, eg Tasmania and other places.
Seems they will say one thing to get elected and do other once in.
I just love how the shop was 100m away from the VDSL, what a joke. How about some Real World testing lke most of us will receive and have the node set up 300 - 400 m away from homes like it will be for me. Then publish their findings. I do not have much faith in the NBN Co or anyone that has been appointed by sir Mal as they are just "Yes" men as Sir Mal does not know the word "no".
In 10 years time once the FTTN has been completed they will have to replace the nodes as manufacturers will not be making the nodes in 10 years time.
In 2001 FTTN was rejected as the technology was not future proof.

This speed result is the high water mark for FTTN in what is indeed a very limited test. A single VDSL connection doesn't have to cope with crosstalk from other users in the same copper bundle that otherwise reduces the achievable speeds. It is also over a relatively short distance when we know that speed drops off more rapidly with VDSL, and that expected operating distances of 800m+ are likely given the number of nodes they have earmarked. I'm sure it will be rubbing salt in for some people who get stuck at the far end of a copper connection, bearly able to achieve 25Mbps, to know that just down the road there are premises getting 4x the speed. So come on NBNCo, lets see test results that aren't obviously "cherry picked" to show FTTN in the best possible light.

Adam's bio note says: 'Adam Bender covers telco and enterprise tech issues for Computerworld and is the author of dystopian sci-fi novels...'
So his next novel could be the dystopian sci-fi titled 'Turnbull's Claytons NBN, worm hole to old era pseudo broadband.'

So much for the promise of FTTP continuing to be installed for business grade internet connections.

Test in ideal conditions: 105/45

Guaranteed speed: 25/1

Meanwhile, those connected to FTTH are already able to sign up for 1000/400.

Potential for FTTN: Zero
