If a FOC back bone is cut and we are solely reliant on it


No-one is suggesting we become solely reliant on it. You can get cheap USB modems that can take over to send emails etc while it is down. There are plenty of options and the market will adopt those as backups to the extent needed, just as campanies have backup diesel generators if it is really that important they have a constant supply.

So once again, no problem.


Do you honestly expect a telecommunications company would maintain existing networks once the FOC is rolled out?

You are showing your ignorance, if you think emails are vital to corporate network services.  You can pick up a mobile phone and call anyone you need to communicate with, communicating with CRM's and other critical software between various locations would be simply impossible.  We have an 8mb/s link between our offices that struggles at times to maintain reasonable connection speed depending on demand and processes.  When that goes down, we can do absolutely nothing; might as well go to the pub.  Wireless USB dongle would be a complete waste of time.


The proposal is that, once fibre is connected to premises, the copper will be decommissioned. In that sense, the premises will be reliant on the fibre, just as they relied on the copper before that. I gather the equipment to splice fibre is far more costly that the tools used to work on copper. With the necessary equipment, however, a skilled operator can often repair fibre faster than similar damage to copper. Or so I'm told.

Overall, the only substantial differences are the far higher speed and development potential of fibre and the fact that fibre doesn't carry current, so equipment power must be provided locally. Point-to-point (as distinct from broadcast) wireless can provide a backup. Speeds of 100 mb/s are possible, provided there's only one user.

It's not so much the equipment, which is costly but a necessary investment, but the downtime involved in repair.  Look no-one will care if their internet services at home are cut for a couple of dyas; it would be a minor inconvenience; however imagine South East Queensland has no internet communications for 3 days; disaster of a magnitude no-one really understands.

To answer my question posed earlier for those unfamiliar; Australia's most valuable terrorist target is a 12 story building smack in the middle of Kangaroo Point Brisbane, most Brisbane residents would be familiar with the eyesore that is the Telstra communications hub directly across the road from the Gabba, the ugly grey building with only a handful of windows.  If that building gets taken out Australia loses communications to the entire eastern seaboard.  QLD, NSW & VIC would have no comms capabaility; nothing; zip; nadda; zilch.  The country would come to a grinding halt which could take years to repair.

I'm not for a second suggesting that significant improvements in connectivity and speed won't lead to the suggested improvements and nor for a second am I suggesting that those in the bush shouldn't have access to high speed broadband; but if FOC is to be the carrier it needs significant redundancy built in to it to avoid the comms disasters that will occur many times daily when it is cut in various locations.

This should be proof to the libbos that private enterprise doesn't always deliver. They would prefer to stagnate the technology whilst ripping off the punters for old outdated and obsolete technology and screw them for as long as they can Sad

Just look at all of the vendors still ripping off the punters for dial up connections. They should be giving that stuff away for free !!


I agree - it's a disgrace to sell people dial up.
It should be free.

Sure. fibre won't replace mobile phones, which is the network used by USB modems, and won't work on your laptops, so that technology will continue to work.

I'm not talking about mobile solutions here, of course they will be maintained, and beggars belief you could think I was asserting otherwise.

I don't, what makes you think Fibre will be cut less often than copper is?

Repairing copper is a fairly quick fix.  It happens with amazing regularity, multiple times daily.  Dial before you dig should be mandatory and cutting a cable without having done so should carry a jail term or public stoning.

What makes you think that the network has been designed without an appropriate level of redundancy?

Not strictly technical, but some economic support (not focused on Australia) at: http://www.oecd.org/document/58/0,3343,en_2649_34225_44245946_1_1_1_1,00.html. Amongst other things, it shows that a fibre-to-the-home network like the NBN could pay for itself in 10 years, even if fully government-funded. It requires spill-over savings of between 0.5 per cent and 1.5 per cent in just four key  sectors: electricity, health, transport and education.

So why do you think it matters if copper gets decommissioned? Do you think we should stick with inferior technology so that it forces us to maintain other inferior technology?

It will have some redundancy.
In some remote areas there will just be one cable inside a pipe
with many fibers -
for the whole district with maybe thousands of customers using it.
Outages will take days to repair.

It will have some redundancy.

As with all such projects, the network has been designed with an appropriate level of redundancy.
Quote:

In remote areas, cables are ploughed into the ground. No"pipe". By the way, the "pipe" is called a duct. Access to Telstra's ducts is one of the things the government is paying $11 Billion for.
Quote:

Yes, each cable holds many fibres. Single fibres are used mostly within structures. For difficult situations, they can be blown through confined spaces.
Quote:

Which differs from copper, how?
Quote:

In view of your demonstrated ignorance, I'll take that with a grain of salt. I'm reliably informed (by people who do the job, so they know what they're talking about) that, with the appropriate equipment, there's little difference in the time it takes a skilled operator to repair damage to fibre to what it takes to repair similar damage to comparable copper.

Paradoxically, with the best equipment (which is admittedly very expensive), a less-skilled operator can be quicker with fibre than copper. Which surprised me.

I really doubt that.
It takes a long time just to find the right 2 fibers to connect &
actually join them.

Of course you do. For some reason, you're pushing a case beyond the bounds of logic and evidently well beyond the bounds of your knowledge.

And with copper, they jump out and wave their (metaphorical) hands?

Stop being so obnoxious.
I am qualified in Electronics.
When a cable with a large number of copper pairs is broken they
are simply buzzed out with a multimeter & joined used a telephone
link for communication from the other end.
It's a lot harder to locate the right optic fiber & join it compared to copper.
