Meta Plans $10 Billion Global 'Mother of All' Subsea Cables 63
Meta plans to build a $10 billion private, "mother of all" undersea fiber-optic cable network spanning over 40,000 kilometers around the world, according to TechCrunch. The project, dubbed "W" for its shape, would run from the U.S. east coast to the west coast via India, South Africa and Australia, avoiding regions prone to cable sabotage including the Red Sea and South China Sea.
The social media giant, which co-owns 16 existing cable networks, aims to gain full control over traffic prioritization for its services. The project mirrors Google's strategy of private cable ownership. The construction could take 5-10 years to complete.

There's more latency in fiber optic than LEO satellites. I'm talking about satellites that are in orbit at 250 mile altitude. Light travels 30% faster in space than in a vacuum .. not to mention all the extra distance a cable has to follow due to land topography. If a cable is a mere 2000 miles long (Europe to USA is about 3500 miles, FYI .. Japan to USA is 5500 miles) .. that would have more latency than a satellite link.

Don't forget that if you put the worlds internet in space, you are committed to a never ending cycle of launching satellites to replace the other satellites that you launched before. If something like a kessel Event happens - and since everyone thinks that satellite internet is utter perfection, it simply will happen.

Speed-wise yes, latency-wise unlikely because the distance is further you have hundred to a thousand or two of extra kilometres to and from orbit depending on the location of the satellite plus added distance bouncing between satellites whose positions shift as they orbit. Also satellite bandwidth is tiny compared to undersea cables. Also the estimates I have seen for the full-size V2 starlink satellites is around 100Gbps per satellite compared to ~10+ Tbps for modern undersea cables.

You only have to be able to multiplex over 100 of those thousands of satellites to reach ~10 Tbps.
You are nothing thinking this through properly. You need 100 parallel routes between A and B on the ground, not just 100 satellites. You will need 100 satellites accessible at point A to handle the upload, then 100 parallel transmission routes between satellites to reach point B and then 100 satellites in reach of the groundstation to download back to the surface. That's going to be thousands of satellites in total with hugely complex upload and download stations to ensure that they can always reach 100 sa

then your total network bandwidth isn't limited to the bandwidth of one satellite.
That is how bandwidth works when you have only 2 customers - one at each end of where you're transferring data. Starlink isn't deploying 34000 satellites to get a signal to the other side of the world, they are deploying them to get the signal to the millions of users on the ground, each providing their own load on the satellites reducing the available bandwidth.
Even now the Starlink network doesn't attempt to get a signal from end to end. It attempts to get to the nearest ground router and then send the re

Read that people, because this guy gets it. I'm not certain where the other poster got the idea that the band the satellite oprates in has more bandwidth than fiber, but a fiber system has whatever bandwidth that you want. Need more BW? Add more fibre channels.
And yes the basic speed of fiber will always be greater than satellites.

On the other hand, you have more distance, both because of the distance up to the satellite and back down and because the signal has to go farther when you're higher up, which cancels out a lot of that benefit.
The planet has a radius of about 6,378 km. So a fiber line halfway around the world would be about 20,000 km long. Starlink is at about 550 km of altitude, so a Starlink path around the world would be 1100 km up and down plus 21765 km, for a total of 22865 km. So almost half of that speed difference goes away because of the extra distance alone. (And geostationary satellites would result in at least twice the latency of the undersea cable even for a single hop, without factoring in any point-to-point link in space.)
Also, every time you relay it from one satellite to another, you're adding latency storing the packets and retransmitting them. If the satellite path involves significantly more hops, that can completely cancel out the rest of the difference.
And of course, there's the bandwidth issue. A Starlink satellite has about 20 Gbps capacity. Even though the story says that they're not planning to deploy it will full capacity at both ends initially, the cable is projected to eventually be able to move data at up to 1 *petabit* per second, which is the equivalent of fifty *thousand* Starlink satellites. And remember that if you're going point-to-point in space, you'd be talking about several satellites handling the traffic, so it is likely equivalent to more like a few hundred thousand Starlink satellites in practice, which is on the order of 10 times the total projected Starlink deployment.
At $25 million per satellite, times say 200,000 satellites, that's $5 trillion dollars, or about 2500 times the cost of this cable, or 20% of the US GDP.
Satellites are great for providing service to folks in the middle of nowhere, because you can avoid a lot of expensive last-mile infrastructure by doing a hop up and back down to the nearest ground station, but they are really not great as long-distance repeaters, because the bandwidth involved just isn't very practical.
