nbn sat launch 230Australia's nbn is running fiber close (FTTC/FTTdp) to 1.5M homes, suggesting it would go "to the end of the driveway." G.fast could go well over a gigabit the short distance but fades rapidly after ~250 meters. G.mgfast could carry 4 gig the length of a very long driveway. (50 meters.) VDSL doesn't make sense unless most of your customers are 500 meters or more.

The difference in cost between VDSL 35b (200/40) & G.fast (750/750) works out to less than $2/month unless you are wildly overpaying. nbn is building to G.fast distances. There's no good reason not to deploy. BT has well over a million lines of G.fast DSLAMs deployed, so there is no doubt it works fine.

We are getting data that customers do want the higher speeds. Alan Breznick reports 10-20% of new customers at Mediacom are buying a gig, even though prices start at $125/month. Australians are ordering slow speeds (25-50 megabits) because unfortunate political decisions make better speeds far more expensive than costs would justify.

Everything at nbn is intensely political as the national network has been at the center of politics for a decade. nbn is somewhere between $10B & $30B below breakeven, depending on your assumptions. It will need a direct or indirect government subsidy unless drastic action is taken. (The official denials are unconvincing.)

There's actually a natural way to reduce that: get maximum value from the fiber in place by using it for backhaul for wireless. Dark nbn fiber could be used for connecting government buildings. Both would induce massive opposition from the carriers. Turnbull only has a 1 vote margin in Parliament. A company the size of Telstra could bring down the government if angered.

Also smart but even more dangerous politically is to lease nbn dark fiber to all comers. That would be a modest proposal.

Many of the newly added homes have coax for cable but there were issues with the cable networks nbn purchased. In some cases, the cable was replaced by fiber rather than repairing the cable problem.

They are using Netcomm Wireless 1-4 line units for the DSLAM. Netcomm is an Australian company that has quietly won contracts in places like AT&T. They were among the first to demonstrate G.fast line powering. They may have brought linepowering back to VDSL as well, but I don't have solid information.

If Australia still had cable competition, they wouldn't even be thinking of anything less than G.fast.

 nbn™ Fibre to the Curb explained

Fibre to the Curb is a new access technology that will form part of the nbn™ broadband access network rollout to provide access to broadband services to Australian homes and businesses.

An nbn™ FTTC connection is used in circumstances where fibre is extended close to your premises, connecting to a small Distribution Point Unit (DPU), generally located inside a pit on the street. From here, the existing copper network is connected to the fibre to form the final nbn™ connection. To power your FTTC service with electricity and provide your connection to the nbn™ broadband access network, an FTTC nbn™ connection device will be required inside your home or business. In some cases, you may be eligible to perform self-installation of the nbn™ connection device. 

FTTC is planned to be available from early 2018. Check your address to see when the nbn™ broadband access network is being rolled out in your area.

NBN Co pushes fibre further and relaunches HFC services

NBN Co takes further steps to advance network and customer experience

NBN Co, the company building Australia’s broadband network, today announced it would increase its planned Fibre-to-the-Curb (FTTC) footprint, with an additional 440,000 homes and businesses around Australia set to receive the new technology.

This takes the total planned FTTC footprint closer to 1.5 million homes and businesses by 2020.

The additional premises added to the FTTC footprint were originally planned for the Fibre-to-the-Node (FTTN) ‘long-copper lines’ and ‘infill and extension’ premises within the existing planned HFC footprint.

These premises are inside or adjacent to existing Telstra HFC network coverage but are not able to connect to the Telstra HFC network.

In line with our strategy of using the most cost effective and time efficient technology in any given location, NBN Co will use the existing copper lead-ins to connect these properties to FTTC.

HFC set for re-launch

In addition to announcing the expansion of FTTC premises, NBN Co has also announced that it will begin a staged re-sale of wholesale HFC services to retailers from 27 April 2018.

NBN Co plans to initially release around 1000 premises in the nbn™ HFC access network footprint in Melbourne and Sydney.  The company is planning to release around 38,000 HFC premises by the end of June in select areas across Brisbane, Gold Coast, Sydney, Melbourne, Adelaide and Perth.

From July onwards NBN Co expects to significantly ramp up the release of HFC premises to retailers, forecast to hit around 100,000 premises per month.

NBN Co has undertaken considerable work on the HFC network ensuring network performance and stability has improved substantially and a better service experience will be made available to end-users.*

The optimisation program will continue across the HFC network and NBN Co will update its website in the coming weeks to reflect these changes starting with those that will be declared ‘ready to connect’ in the April-June period.

NBN Co CEO Bill Morrow said:

“We are pleased with the improvements seen from the additional work undertaken while sales have been paused on the HFC network. We expect to see an uplift in customer experience as a result of these improvements.

“We are also excited to announce we will be expanding FTTC to cover an additional 440,000 in areas where some long-copper FTTN and new HFC lead-ins were previously planned.

“The team remains at the forefront of technology developments and continues to innovate to bring the best network to all Australians, as quickly and affordably as possible.

“The flexibility of the multi-technology mix allows us to choose the right technology for each area and deliver the project on time and on budget.

“We remain confident of reaching our goal of completing the build and connecting eight million Australian premises by 2020.”
