Yeah no wonder. The administration he’s part of is behaving unconstitutionally, so it’s only logical he would condemn the Office for the Protection of the Constitution in other countries for doing its job. Can’t have that if you want to erode the democratic basic order.

Wow interesting! Thanks for checking the label!

Yes, and that’s before muxing!

I need only 75 GHz of spectrum to send 400 Gbit/s through our country. We’ve currently got a link running between Zürich and Lugano (two amplifier sites in between, before and after the alps), and I’ve got 4400 GHz of usable spectrum with our currently deployed system, so if we needed it and spent like two million dollars we could deploy 23.2 Tbit/s within months, using just our normal commercial stuff, on a single fiber pair.

Using G.657.A2 fiber you could get away with 7.5 mm bend radius, or 15 mm diameter, for the innermost layer of the spool. That’s around 5/8 inch for freedom units.

But then again if you went that tight you’d need like 56’000 windings for 10 km. That sounds like a fuckton, and like we can’t ignore the outer diameter being larger.

Approaching it from the other side: The fiber diameter with coating but without any mantle is 0.25 mm. If you want to put 10 km on a 100 mm long spool you could put in 400 layers lengthwise, and each layer would have to be a spiral of 25 m (of course you’d spool it outside in, not layer by layer, but should be mathematically similar enough). Using this spiral calculator and some random changing of the values it looks like an outer diameter of 91 mm (3 & 5/8 inch), and inner of 15 mm and a thinkness of 0.25 mm would work for a 25 m spiral.

Or if we go for 125 mm drum length, so 500 layers, with 20 m each we get 82 mm (3 & 1/4 inch) outer diameter.

Or if we go for 150 mm drum length, so 600 layers, with 16.7 m each we get 75 mm (3 inch) outer diameter.

So yeah I think your estimate was pretty spot on, if the 10 km length is the right assumption.

Today’s wires aren’t actually wires, they are optical fibers. It must be G.652 or G.657 from telecom use, since that’s commercially available en masse. I think most likely would be G.657.A2 because that can be bent tighter. Here’s an example data sheet from a random google search. I wrote it in a different comment already, but the core has 9 micrometer, the cladding 125 micrometer and the coating 250 micrometer diameter. For telecom applications you’d add at least a mantle, or more likely use a cable with many fibers in little pastic tubes wrapped around a metal core for stability, 12 x 12 is fairly standard. Here of course it’s just a single fiber without mantle being spooled off.

Bidirectional transceivers (so both directions on a single fiber) can do 100 Gbit/s ethernet too. No way you’d do that for drones of course, but just to show how far you can get with a single fiber.

bend the fiber around a pencil and only experience degraded signal

Interesting. Are you using G.657.A2 then?

Those news are already not so new any more. We’ve had reports of those two months ago.

Since fiber optic wire guided missiles exist it’s not that much of a leap to think it should work with drones too, so long as the weight works out.

Fiber is really really thin. 9 micrometer core diameter and 125 micrometer cladding diameter (incl core) and 250 micrometer coating diameter (incl core, cladding). The 10 km spools we use in our lab for network equipment testing are boxes of only like 20x20x10cm, and those aren’t optimized to be extra small with bend insensitive fiber. I can totally believe the 1.2-1.4 kg for 10 km in the article.

Edit: leak -> leap

If the Republican administration wanted to win a trade war against China they could have really used some allies, to make sure they had equivalent size as a bloc. However they preferred to start a trade war with 182 fronts at once.

Maybe they should have used some of that very profane UV light on their holy water, to make it safe, not just holy.

I checked and this does seem to fit for Switzerland.

Trade deficit of US to Switzerland: 38.5 B
Exports from Switzerland to US: 63.4 B

Ratio of the two: 61%

Half of that as “reciprocal” tariff: 31%

Sure, I’m not opposed either! Just want to make sure people here have the information needed to not be disappointed later.

Coronaviruses are not the only cause for what is considered the “common cold”. I remember that some Rhinoviruses, Adenoviruses and I think a forth family of viruses also cause symptoms that are counted as a cold. It’s kind of a catch all term.

Though they have less immigration, a bunch of those languages originate closer to China than the USA, I bet they can find staff equally well, if they really aim for a 1-to-1 replacement.

Isn’t Voice of America like the USA’s equivalent of Deutsche Welle?

Basically a vehicle for internationally transporting news from the US American perspective?

Trump really hates any and all soft power the USA have available.

I have some doubts. Only small or weird outlets have any news on this and there is no good original source linked anywhere.

The Canadian Press explains a potential path by which this claim could have arisen, namely that Slim’s company América Móvil had stated in an earnings call that they were going to invest 22 billion pesos (! not USD) in infrastructure over three years and they didn’t have plans to invest it in Starlink, instead looking more towards two other satellite companies, and only for rural backbones where laying fiber would be more expensive.

Just to make sure I got the right Arabic prince here, that’s the guy who ordered Khashoggi’s death, right?

I’m not above realpolitik, if his interests actually align with supporting Ukraine I’m happy to hear it.

I like it, but I’m a little confused.

Why does an individual province determine trade policy? Is this normal for Canada?

The Frankfurter Rundschau additionally writes

Wie Nikita Lofving, eine befreundete Kollegin Brösches der Zeitung sagte, soll das Tattoo-Equipment, das die Berlinerin bei sich trug, den Grenzbeamten als Verdachtsmoment ausgereicht haben, dass Brösche in den USA arbeiten wolle. Lofving sagte, Brösche habe lediglich sie tätowieren wollen – unter Freundinnen und eben nicht kommerziell.

Jessica had tattoo equipment with her to tattoo Nikita, but that equipment made the border police suspicious that she was trying to tattoo American customers illegally on her tourist visa.
