It's not the speed...

...it's the latency. You can hit that speed with traditional glas-core fiber. You just can't get 99.7% of the speed of light in that fiber (it's closer to 65%). I mentioned this in a couple comments on Engadget.

Basically renders DDoS useless for a while because botnets' 300gb ammo can't destroy a 73700gb structure?

It isn't useless.

I'm sure transcontinental fiber runs would benefit quite a bit from the ~30% lower latency from hollow fiber. But for this to happen, they would need to get the attenuation down to the conventional glass fiber 0.2-0.3dB/km range.

The only real news in this article is a new speed record for hollow fiber... but as someone said above, similarly high speeds have already been achieved on conventional fibers over long-haul fibers (the stuff that really matters) so the speed claim itself is not particularly impressive.

I'm sure the ultimate goal is to produce long-haul hollow fiber but at 3.5dB/km, they most likely still have a long way to go to get there.

At least somebody got it! Thank you Motoracer. I was simply pointing out the irony of the VZ CEO (and others) claiming there is no market for Gigabit Internet while technology continues to increase the boundary of fiber's usable speed.

Re: Verizon CEO says:

In security and ISP hosting, there is. Especially when botnet and DDoS incidents starts to rise.

Higher latency threshold means less likely to take a huge hit from gigabit ddosing right?

fiber is already capable of transmitting terabits per second. This won't make any difference there.

This could be good for data centers between systems and for network based storage, but likely not for consumers.

There is more to the world than consumer Internet connections and current fibre technology is not a limiting factor for anything that would be delivered for a consumer Internet connection.

Next the traders will be using fibre that has the signal arrive before it is sent.

That was my first thought when considering who would adopt this now. Short runs, they care about nano-seconds, early-adopter cost = non-issue.

Emotionally driven opportunistic social commentary: I'd just as soon like to see practitioners of high frequency trading buried alive with their new fiber.

I need that!

If I had that kind of bandwidth. I would have an online cloud that would make daily full backups of all of my computers. Also I would use it for video streaming HD 1080P and 4K when it comes out.

makes perfect sense...

from my ee classes (that i thought i had drunk away) -- n of glass is ~1.5.
remove the glass -- n~1.
you remove a lot of barriers around permittivity.

now if it can be mass produced...

Sounds like a great replacement...

...for existing multimode fibre, which tend to be intended for short-distance runs (up to ~6 miles / ~10 kilometres), and already have a 2.5-3.5dB loss per kilometre. Reference:

What am I missing?

quote:
To achieve the transmission rate of 73.7 terabits per second, the researchers used wave division multiplexing (WDM) to transmit 37 40-gigabit signals down the hollow fiber.
40 Gbps * 37 = 1,480 Gbps
40 Gbps * 37 != (does not equal) 73,700 Gbps

Their math (or the quoted numbers) is off by a factor of 50.

what's practical?

the majority of residential subscribers can't get or can't afford speeds of over 100 megabits to say nothing of gigabit & beyond. the networking equipment beyond 1 gigabit is prohibitively expensive for regular Joe Schmo.

it will be a decade or perhaps never that residential broadband hits speeds of 1 gigabit symmetric given the companies who OWN the last mile through monopoly, duopoly and consumer apathy.

what's also interesting, you don't hear many FTTP companies ready to even talk about 10 Gigabit ONTs as the cable industry is in R&D/pre-construction phase over re-organizing spectrum to get 24mhz channels on their last mile docsis 3.1 deployment.

How about a fiber optic cable that has none of these signal loss issues & is cheaper to make than current FO cable? That would be impressive... this? Not so much.

Look at the loss

The loss makes it completely impractical for any major applications. Just useful for intrafacility transmissions really.

pointless

No real point.. The deployment will be a joke and to people with 5 options already, and then they will just cap the crap out of it.. Just put all research to sleep till companies decide to let the consumer have fun with the internet again and god freakin forbid build it out more with the USF funds rather than horde it claiming its for maintenance for POTS that hardly noone use's any more..

The usual clueless

As usual anything posted about fibre and the clueless come out. OMG I won't receive a ridiculously fast Internet connection at home so there is no point at all. Completely clueless. Because there is nothing else to the Internet but your home connection.
