Submarine Cable Map 2023
- mmwelt 3y agoThe interactive online version is available here: https://www.submarinecablemap.com/ https://www.submarinecablemap.com/
- Tempest1981 3y agoMuch better, thank you.
- h0nd 3y agoI was looking for this as I was surprised that a map would be displayed the way it is in the shared link.
- ezequiel-garzon 3y agoI love these maps, and I'm glad they provide downloads like [1]. I wish the resolution was a bit higher. As it is the names of the towns on the coasts can be read with difficulty.

- dotancohen 3y agoWow, that map is very political. Israel is not mentioned by name, but the Palestinian Territories are.
- josh_frome 3y agoTelecom Egypt is the sponsor of the map
- Kye 3y agoThere is no selection of labels for disputed territory that will make everyone happy. It's inherently political.
- dotancohen 3y agoWith the exception of the ambitions of fringe terrorist groups, the land that Israel has ruled since 1948 is not disputed territory.
- jacooper 3y agoSo writing Israel isn't Political? Your definition of political is obviously biased.
- dotancohen 3y agoWould writing Germany be Political? Writing Ukraine? These nations exist and are functioning parts of international relations.
- deleted 3y ago[deleted]
- jacooper 3y agoWell Germany isn't occupying lands illegally or commiting war crimes every minute.
- dotancohen 3y ago1. Neither is Israel, despite how your news source is trying to manipulate you. 2. Those nations that do occupy lands illegally and commit war crimes are in fact listed, so that disproves any connection to your supposed reason and the real reason for eliminating the name of the state of Israel.
- jacooper 3y ago> 1. Neither is Israel, despite how your news source is trying to manipulate you. It's's occupying lands illegally according to the international court. https://www.amnesty.org/en/latest/campaigns/2017/06/israel-occupation-50-years-of-dispossession/ https://www.amnesty.org/en/latest/campaigns/2017/06/israel-o... https://www.ohchr.org/en/press-releases/2022/10/commission-inquiry-finds-israeli-occupation-unlawful-under-international-law https://www.ohchr.org/en/press-releases/2022/10/commission-i... > 2. Those nations that do occupy lands illegally and commit war crimes are in fact listed, so that disproves any connection to your supposed reason and the real reason for eliminating the name of the state of Israel. This sounds eerily similar to people trying to justify the apartheid in south Africa, oh our allies don't say it's bad so it's fine! The end of the Israeli occupational doesn't mean the deportation of Jews, Jews lived in Palestine in Peace with Muslims and christians for a long time, it's a holy land for all three religions.
- h0nd 3y agoMaybe to avoid politics, the name of the region was used.
- dotancohen 3y agoThat would have been an acceptable explanation in the 1950s or early 60s. But after 1964 one of the sides adopted the regional name as a national identifier, thus invalidating it as a neutral name.
- mikae1 3y agoToo bad it's a rather shitty JPEG that's blotchy in the more uniform "white" areas. I've been able to compile a map from the png tiles for the earlier versions of this map. It uses mapbox.js and tiles have URLs like this one: https://tiles.telegeography.com/maps/submarine-cable-map-2023/3/2/1.png https://tiles.telegeography.com/maps/submarine-cable-map-202... https://dezoomify-rs.ophir.dev/ https://dezoomify-rs.ophir.dev/ is helpful.
- davedx 3y agoIf the world could run power along all these submarine telecoms cables then we'd be a lot further towards solving the problem of renewable power generation. I wonder how these kinds of cables compare to HVDC cables in terms of size and cost.
- ccakes 3y agoThey do, any cable over about 1000km has active repeaters on the seabed which need to be powered. There is HVDC equipment on both ends and typically each end is sufficient to power the entire cable independently to allow for the cable to continue running through maintenance, shunt faults (basically something earthing out on sea water) or a single failed repeater.
- Kim_Bruning 3y agoThere's a rotating sphere at the top of the map, but part of it is black, and apparently you're not supposed to use it? It's just decoration? You scroll down to what you think is the map, but it immediately gets covered by a caption, so you scroll down more ... It turns out that downloads for the actual map are at the top of the page.
- FL410 3y ago...but only after you scroll all the way to the bottom. What a horrible design.
- joering2 3y agoCame here to say the same. And clicking on the globe does not stop it. Then trying to zoom and you can't but the globe image is too blurry/low res to read what's on it. Don't get me even started on scrolling...
- Tempest1981 3y agoYeah, very frustrating to see just the Pacific Ocean w/o text blocking half of it. Fortunately mmwelt posted another link for exploring: https://news.ycombinator.com/item?id=38503448 https://news.ycombinator.com/item?id=38503448
- cliffordc 3y agoIs there somewhere we can see submarine and land cables both?
- ivix 3y agoLand cables are usually considered classified/sensitive information, so no not generally.
- ris 3y agoDear map widgets in 2023, Stop asking me for WebGL, I will not give it to you.
- aaron695 3y ago[dead]
- _whiteCaps_ 3y agoIf this sort of thing interests you, I highly recommend "Mother Earth Mother Board" by Neal Stephenson. Probably my favourite piece of writing in Wired. https://www.wired.com/1996/12/ffglass/ https://www.wired.com/1996/12/ffglass/
- everybodyknows 3y agoAre any of the spatial datasets that may have gone into this available for public download?
- sklargh 3y agoDoes anyone else find it a little weird that the Great Salt Lake is shown on the map but Lake Champlain and Lake of the Woods are not?
- dotancohen 3y agoI just noted in another comment how the map is very political in its choice of things to label.
- huytersd 3y agoSo is dijibouti some massive switching station hub or do those cables just go by it underwater?
- toast0 3y agoMy understanding is most of the multipoint cables are not switched at every point, it's more of a bundle of cables where each point gets a strand or two to every other point (or selected points, maybe the anchor points connect to all others, but minor points might only connect to the anchors and not each other). That said, Djibouti is a major cargo transport hub for Ethiopia, and is probably a network transport hub as well. Ethiopia is the 2nd most populated country in Africa and that would justify a lot of cable landings.
- maxlin 3y agoThis has to be the worst possible way to present this. Just give us a, you know, MAP. With openable annotations and panning so we aren't locked in some view we didn't navigate to with tons of info about something we didn't actually seek out.
- deleted 3y ago[deleted]
- tiahura 3y agoI'm not seeing my favorite, Honotua. It connects Hawai'i to Tahiti. https://en.wikipedia.org/wiki/Honotua https://en.wikipedia.org/wiki/Honotua
- xkekjrktllss 3y agoI have a 5k display and I can't even quite make the page wide enough to view the entire globe. How are people with regular displays supposed to view it? What a disaster of a presentation!
- nemoniac 3y agoSome years ago I visited the Transatlantic Cable Station on Valencia Island off the west coast of Ireland, from where the first submarine telegraph cable was laid to Newfoundland in 1857. After several attempts the cable reached Newfoundland in 1866. Before that moment the fastest way to get a message from Europe to America was aboard a ship; two weeks or so. After that it could be sent over a cable with Morse code. https://valentiaisland.ie/valentia-transatlantic-cable-station/ https://valentiaisland.ie/valentia-transatlantic-cable-stati...
- gist 3y agoWell a random check of one cable (Gemini Bermuda) shows it was decommissioned in 2004. I wonder how up to date the rest is (based on this one entirely random check). https://en.wikipedia.org/wiki/Gemini_(submarine_communications_cable) https://en.wikipedia.org/wiki/Gemini_(submarine_communicatio...
- Thaxll 3y agoI mean the website is crap, how do I see the map as a whole?
- Galacta7 3y agoTry this link instead: https://www.submarinecablemap.com/ https://www.submarinecablemap.com/
- zrail 3y agoHow do these cables split in the middle of the ocean? Is there a fiber switch laying on the ocean floor?
- Maakuth 3y agoNo idea of what precise sort of hardware is there, but the fact is that these cables consist of a bunch of fibers. Dozens of them typically, quick search suggests up to 144, but I doubt that's a physical ceiling. So I suppose they make a branch when needed, with some number of fibers going to another direction.
- rdl 3y agoThere are repeaters on the cable every ~50-200km (depending on technology), powered by DC power carried on the cable. There are branching units powered the same way -- I believe they handle branching at the fiber level, rather than waves, but not sure of the specifics on modern DWDM cables. (they can run ~80-160 different frequencies of light on the same fiber, and the cables contain multiple fibers...)
- aDfbrtVt 3y agoQuick correction - not repeaters but amplifiers. The term repeater is commonly used to refer to a device that demodulates and remodulates a signal.
- rmah 3y agoIt's interesting how Europe-Asia interconnects are so small relative to US-Asia and US-Europe.
- jedberg 3y agoThis is only undersea cables. Europe and Asia have overland connections too. But mostly it's because both continents do more business over the internet with the US than with each other.
- jedberg 3y agoGiven all the compute infrastructure in Ireland, I'm surprised it still has no direct connection to continental Europe (they all go through the UK first).
- SnorkelTan 3y agoThe reduction in latency and additional throughput is probably not worth the cost. I’m sure the cable operators have considered this.
- Scoundreller 3y agoI wonder if they put in a "long-way-around" splice into these forks in the Atlantic, so Ireland would have a connection to Denmark: https://www.submarinecablemap.com/submarine-cable/havfrueaec-2 https://www.submarinecablemap.com/submarine-cable/havfrueaec... Then you've got this link to the SW tip of UK, that then links to France (via Guernsey & Jersey): https://www.submarinecablemap.com/submarine-cable/pan-european-crossing-uk-ireland https://www.submarinecablemap.com/submarine-cable/pan-europe... There might be an overall direct fibre link. But yeah, Ireland is at risk of the UK cutting most of their continental Europe capacity. I've seen some strange investments though that don't seem to add much more on top of what's already there, like this company's: https://crosslakefibre.ca/network/ https://crosslakefibre.ca/network/ But maybe despite ample existing infrastructure, the incumbent providers suck so they can make a successful go at providing a bypass.
- Scoundreller 3y agoThe Katittuq Nunavut Fibre Link, labelled as 2025, had its tender cancelled this year. https://www.cbc.ca/news/canada/north/nunavut-cancels-tender-for-fibre-optic-line-internet-1.6900346 https://www.cbc.ca/news/canada/north/nunavut-cancels-tender-... > Nunavut is the only province or territory in the country [Canada] without access to fibre internet. The project would bring fibre to both Iqaluit and nearby Kimmirut. Right now, everything is over satellite. Too bad the big "internet cache" systems don't have sneakernet approaches to filling their caches. Unsure if their local ISP does any kind of caching. So every stream/download/update, etc. is its own "hit" over the downlink. Thanks to Canada's terrible mobile telecom pricing and lacklustre competition, a cell phone with a dataplan in this territory is cost-competitive with the rest of the country... https://www.qiniq.com/mobile/#plans https://www.qiniq.com/mobile/#plans
- betaby 3y agoThe whole territory of Nunavut is under 40k habitants. It's totally fine to serve it with satellite. Also I don't see how any completion is possible, again, for a territory with under 40k habitants.
- ericra 3y agoIt's amazing how many cables there are routing through the Suez Canal, especially directly connecting Mumbai all the way through to Marseille. I wonder how well protected they are specifically in the Suez Canal. Presumably the whole area is pretty well surveilled by the Egyptian government, but I have no clue. I just think it's really interesting how many cables are (understandably) routed this way and wonder whether there is full backup redundancy in the few cables running around south of Africa.
- 082349872349872 3y agoI was initially surprised by how highly the cable map correlates with canonical surface traffic routes, but upon reflection I guess the basic economics of trade centres drives both, so I should've expected it...
- _8j50 3y agoIf fiber cables like these are possible, why not pneumatic tubes maybe 1 meter in diameter. Think of the economic and environmental implications!
- analog31 3y agoThe pressure.
- vikmals 3y agoDoesn't work
- ThinkBeat 3y agoIs it safe to assume that there exists a lot of cables that we are not supposed to know about or at least that are not public and not on such amps? I have long been thinking that the NSA must have some high capacity "black" cables to help the surveillance of the internet. Primarily to capture data, sending all the captured data back through the public internet would be counterproductive. A 5eye private subsea network? I would assume other countries have some for similar reasons
- dmvdoug 3y agoWell, SOSUS had cables that people knew fed into landing stations on the coast but what exactly they were for remained classified until like the 1980s. So those are literally classified government cables. If you mean secret Internet cables, I have no clue, but hey, history teacher had a history answer so… hi. :)
