Loooooooooonies...

[andrewducker]

You think?

I like crazy when the crazy is that crazy.

Someone's trolling with "Why Do Non-Conservatives Exist?" but it's hard to tell who.

[momentsmusicaux.livejournal.com]

You think? I'm scared they're deadly deadly fucking serious.

[ashfae.livejournal.com]

I'm afraid they are. Sometimes I really don't miss my country.

Poe's law says that there's an even chance that you're right. But to me it just reads like 4chan has been in there, and the more subtle trolling hasn't been detected and reverted.

It'll be a bundle of fibre optic cables, so it's very upgradeable.

[dalglir.livejournal.com]

It's certainly a major investment but a 100Gb backbone connection isn't _especially_ big between two large and geographically close (on a global scale) cities.

If they're bundling, say, OC-768/STM-256 lines then 100Gb shouldn't too hard to reach. Not really sure why it's news :)

[pete stevens (from livejournal.com)]

Isn't it 100G on a single wavelength, so one 100G interface rather than 10x10G or 3x40G ? Using DWDM and 64 wavelengths it'd be upping the capacity per fibre from 640Gbps (10Gbps) or 2.5Tbs (40Gbs) to 6.4Gbps. Janet already runs 40Gbps per transceiver on the main backbone around the UK.

[dalglir.livejournal.com]

Yes - that's along the lines of what I was thinking. OC-768/STM 256 connections are ~40Gb each.

EDIT: I will learn to read things properly instead of just glancing through LJ while I'm working :)

It seemed more insinuated that this is 100Gb on a single line terminating on a single interface. If they've cracked it (which seems backed up by Andy's further link below): well done. If they can apply the technology to existing, laid fibre then that's a good leap forward.

[andrewducker]

That's something I'm curious about - is fibre-optic easily upgradeable by just putting new transmitter/receivers on it? Or do you get different grades of cable?

[andrewducker]

Looks like it's 100G on a single line:

[dalglir.livejournal.com]

Does seem to suggest that it's a 100G Ethernet terminating on a single physical interface.
