https://www.theguardian.com/technology/2018/oct/24/twisted-fibre-optic-light-breakthrough-could-make-internet-100-times-faster


 


 


Fibre optic cables use pulses of light to transmit information, but currently information can only be stored through the colour of the light, and whether the wave is horizontal or vertical.


By twisting light into a spiral, engineers effectively create a third dimension for light to carry information: the level of orbital angular momentum, or spin. “It’s like DNA, if you look at the double helix spiral,” said Min Gu from RMIT University. “The more you can use angular momentum the more information you can carry.”


Researchers in the US had previously created a fibre that could twist light, but Gu’s team is the first to create a reasonable-size detector that can read the information it holds.


Previous detectors were “the size of a dining table”, but the new detector is the width of a human hair. “We could produce the first chip that could detect this twisting and display it for mobile application,” Gu said.


The technology could be used to upgrade fibre optic networks like Australia’s national broadband network


Gu said his new research could still work with networks with large amounts of copper wire.


“We will definitely reduce this hurdle,” he said. “We will make this transfer more efficient.”


However, because the new cables are required to effectively twist light, any upgrade could involve replacing existing fibre networks.


 


 


Sounds exciting but years away from being implemented.

Lolololol not sure how you upgrade a largely copper network.

Looking at it ist DWDM on steriods. That requires a whole lot of new cabling to work..

I'd be happy with some old fashioned straight fibre.

 

i.e. Straight to my gate. sealed

 

But alas, no.

 

We're classed as "rural" at 2km from a fibre boundary.

 

Looks like lifestyle blocks with a front gate every 100-150m along our road wasn't sufficient to make the cut.

 

If only they'd gone with 90% UFB coverage rather than 87%. undecided

Welcome along to the Club! We are in much the same position.

Didn't you know that vectoring magically sticks fibre twirls in the cables?

 

It's just like the advanced glass that's in FibreX!

Low blow bro, but harsh but fair lol.

 

I got a mate who is a Solutions Architect in the Telstra Broadband team. He says hes only got VDSL at his house and its not that far from the city lol.

 

Interesting news though. Imagine the 900/200 100x faster. Is that what its saying or have I got that wrong?

You can say that again. And again.

I've stayed with friends near Sydney CBD (Bondi) and Melbourne (Williamstown) over the past 12 months.

 

I suspect when stating "VDSL" that might be presenting an overly optimistic view of things to many NZers, for example through laziness/inertia, I've still got VDSL which runs at a very consistent 90/30.  Their VDSL seemed to offer about 30/10 when the going was good, but would drop away to sometimes complete and utter uselessness in the evenings. Watch netflix? - ahhhh - maybe. Was better further out in the suburbs.

Their micro dslam thing isn't bad... it's by product of design a bit difficult to congest unless their fibre backhaul is heavily incumbered...

 

 

 

problem is though is their "NBN" doesn't really many anything.

 

It's like our "UFB" some have been known to claim Cable as Fibre...x.. which missleads.

 

 

 

Given nokia is doing a big media speal lately with chorus, i'd suspect it wont be long till it's said our vdsl is "UFB" too.

Unless someone invents a device a la Star Trek to transport people through the network, I can't see any benefit for residential internet consumers to use this technology.

640k will be enough for anyone /s

 

This would be something the likes of SCC and Hawaiki might pick up one day when the tubes start to get too small right?

I feel your pain. My folks house only 10km from a fairly major township but anyone would think we lived in the wilderness. New subdivisions going in around us soon as well, with still no indication of any upgrades.
