Finland’s last analogue landline phones go silent after 150 years.

Finland’s last landline call has been made as the Nordic country becomes the latest to retire copper-wire phones in favour of fibre.

Estonia, the Netherlands, Norway and Spain have already made the jump as countries across the world roll out fibre optic cable that can handle both internet services and voice calls.

Fibre-Optic Curiosity Poll: people who deploy single-mode point-to-point fibre links (any distance beyond inside a datacenter), do you use two-strand optics, or single-strand with two colours? Please #boost!

I very much lean on Bi-Di optics since I figure there's half the amount of OSP cable to go wrong, and swapping failed optics is MUCH easier than splicing a bad strand in an inaccessible flooded underground vault that's on fire.

Let me know in the comments what you do, and why.

[Note top-of-rack/intra-rack and in-datacenter is NOT what I'm asking about that. That's the realm of MMF and DACs.]

Additionally I'm wondering about NNIs and medium-haul 100G+ links, since bidi there is LESS common, but is beginning to happen. LR4 -> LR2 <- LR1???

#Scientists have demonstrated #quantum #teleportation over the #Internet for the first time

It may not be teleportation like you see in the movies, but it's real. Scientists at Northwestern University have successfully demonstrated, for the first time, quantum teleportation via #fibre #optic cables carrying internet traffic.

#China bans export of key #minerals to #US as trade frictions escalate
China has banned exports to the #UnitedStates of items related to the minerals #gallium, #germanium and #antimony that have potential military applications, it said on Tuesday, a day after Washington's latest crackdown on China's chip sector.
Gallium and germanium are used in #semiconductors, while germanium is also used in infrared technology, #fibreoptic cables and #solar cells.

Well shit! Designed this whole light pipe situation for this #meshtastic enclosure, thought it would be sick! But transparent PLA makes a TERRIBLE fibre optic cable. Any suggestions? Big ass fishing line? #3dprinting #lightpipe #fibreoptic #fiberoptic

New research in Optics Express📜! We linked unexpected UV loss in HCFs to gaseous chlorine. For transmission to recover, this needs to diffuse out. This has implications for current goals for long length, high yields of #fibreoptic HCF #Photonics https://doi.org/10.1364/OE.537473

Outside our house they are pulling #FibreOptic cables (and draw cords) into existing ducts for Virgin Media. (AFAICS they didn't have draw cords before, used push rods to get to the next pit, then pulled a draw cord back.) Pulled both ways by us, plus across the road, so there are 3 lots of 4 cables in that pit! I'm intrigued by how these fibre optic cables get joined and junctioned!

Have some festive #RetroComputing - a #Psion 3mx running Agenda, in front of a fibre optic Christmas tree. 😁

No matter what you're doing today, I hope you're all spending it the way that you want to.

While I was doing our #advent #jigsaw, Diana has tested positive for COVID, but after consultation with relatives we'll still be undertaking our #Christmas tour.

However, the good news is that a new power supply should arrive today to light our #fibreoptic #tree again. 🙂

Have you checked your #broadband speed? It’s a fun game #talktalkbusiness has imposed on me as my connection keeps dropping. They say they guarantee a minimum download speed of 56.84Mb. I think I get an average speed of 30. Do check your speed and ask them what their #fibreOptic does actually. https://www.supportal-test.co.uk/

I am looking at adding networks between four buildings in a rural property. Runs are 30m, 60m, 80m and 180m.
(I have a soft spot for digging trenches, I love it in fact.) (I also hate wireless, I spend too much of my professional life with it. Wireless miasma will not seep into home life)

I'd hoped that I woulds type in "plastic optic fiber" and get back results selling me cheap, cheery and essentially guilt-free 100 Mbps networking gear. Alas, #POF seems to have been an evolutionary dead-end.

What happened?

Dear #Australian's that pay #rent, what do we think #landlords spend the money on?

a) improving your home (adding #fibreOptic connectivity, solarPanels)
b) building highrise towers that they call investments,
c) lavish holidays and getaways
d) parties
e) #politicalDonations, #lobbying, writing PR and press releases for the #legacyMedia about how important they are, and why they need to siphon more #freeMoney out of tenants.
f) all the above except (a)
g) other, please comment
