Fibre optic cables' data capacity may soon be reached

Interesting article.

He is stating the obvious.

If people would stop downloading blu ray copies of fucking Sandra Bullock movies, then maybe we wouldn't have a problem.

Japan doesn't seem to have this problem. Their cables capacity is 100x that of USA

It's not a new story, but increasingly being told.

Looks like I'm going to be stuck on 750 kbps.

True but don't underestimate technology

This 'story' has been repeated every couple of years since the internet started.

Ooh, we can't possibly have PICTURES, the network will collapse.

Oooh, we can't possibly have MUSIC, the network will collapse.


Oooh, we can't possibly have VIDEO, the network will collapse.


Oooh, we can't possibly STREAM VIDEO, the network will collapse.

Oh and then the stuff about running out of IP addresses.

Etc.

It's a non story.

Here's the BBC in 2007 saying we will run out by 2010.

And here is Cringely 3 years ago explaining about this bandwidth scarcity myth.

http://www.pbs.org/cringely/pulpit/2...05_003153.html

We havent even yet started deploying 40Gbps and 100Gbps ports over fiber... I really doubt we are anywhere near "close" to maxing out fiber optic cables. There's colored optics, etc. to use more bandwidth over existing cabling.

That makes two of us champ.

There was an ENORMOUS glut of fiber laid in the 90's by all of those internet and telco companies that are now out of business. More than the U.S. could have possibly used. Even now Google is laying more, and there are government initiatives on the table to mandate increased access and speed.

Sounds like there was a sale on tinfoil this week.

"640K ought to be enough for anybody." - Bill Gates (1981)

A lot of the dark fiber doesn't run where the backbones are. For example, there's dark fiber from Kenosha, WI to Milwaukee, WI and what fucking good is that going to do?

I will sum things up.

Current DWDM will power 160 channels or waves as we call them them today. The standard for these waves is currently 10Gbps. 40Gbps and 100Gbps technologies are just now emerging. It is only a matter of time from when we go from having the ability to run 160 x 10G over a single pair of fiber to 160 x 40G and 160 x 100G over a pair of fiber.

If the technology, which some cases work on bi-di "bidi" or bi-directional fiber. I.e 1 strand instead of two making up a circuit you can go from 160x to 320x waves on 2 strands of fiber.

Whoever wrote that article doesn't understand how things work.

Lots of good. You can achieve anything with fiber, tv signals, data, voice you name it.

Well, Google has been buying it hand over fist for years. I'm sure the web hosts here can tell us pretty quick if this article is b.s. or not (some already have posted).

Like everytime a story like that breaks out, there is an agenda behind it. Mostly about net neutrality.

According to Gerry Butters,[2][3][4] the former head of Lucent's Optical Networking Group at Bell Labs, Moore's law holds true with fibre optics.[5] The amount of data coming out of an optical fibre is doubling every nine months. Thus, excluding the transmission equipment upgrades, the cost of transmitting a bit over an optical network decreases by half every nine months.[dubious – discuss] The availability of dense wavelength-division multiplexing DWDM and coarse wavelength division multiplexing CWDM is rapidly bringing down the cost of networking, and further progress seems assured.

:1orglaugh:1orglaugh:thumbsup

Bell Labs scientists have determined that the theoretical limit of a fiber is 100 TBPS.

1TBS has finally been reached.

And that's per strand, if you bundle a bunch of strands together then where's the issue? Article has no hard numbers just spews a bunch of FUD, IMHO the article is junk.

this is just the fud drum being beat to justify tiered internet again.

the fact is all that Bit torrent downloading could be solved by setting up reverse proxy, as local area nodes. Everyone would simply get their copy from the node, while the node would be the only one to communicate across the backbone.

The only reason telco don't implement such a solution is bacuase they want to justify tiered internet.
