so the limit is what exactly? quality of the Fiber itself, quality of the glass strands?Not over land with the current cables as far as I can tell. We are limited by the speed of light. With Starlink they are saying there is a chance to reduce latency to anywhere on the planet becasue you dont have to run cables but you still have limitations of speed of light and I doubt we have a lot of demand for low latency to Australia or South America. Nice to have but no huge demand I imagine.
The speed of light is exactly 299 792 458 meters per second in a vacuum.so the limit is what exactly? quality of the Fiber itself, quality of the glass strands?
Now divide the length of the Equiano cable by this fibre light speed. What is the delay.The speed of light is exactly 299 792 458 meters per second in a vacuum.
The speed of light in any material including fibre optic cable is based on its RI or Refractive Index. I think for most fibre cables its.... 1.4. This means that speed of light in a fibre optic cable is 299,792,458 / 1.4 which gives us - 214 137 470 meters per second in a fibre cable.
No idea what lenght it will be but it wont be shorter than what we already have and they are not selling this cable as having faster speeds or a new technology so we can expect latency of over 100ms to EU.Now divide the length of the Equiano cable by this fibre light speed. What is the delay.

Now if only we could actually get that damn 160. I'm seeing 200 to EU in games...For the round trip, you're looking at minimum 120ms (give or take). So add in all your additional local latency and latency from the international landing point out to your destination, I would say 160ms is probably the lowest we'll ever see latency to a system in Europe, with absolutely ideal conditions and minimal hops between everything.
Which is the other most interesting thing about star link, latency Cape Town to Europe, Australia to US, etc.Starlink promised sub 100ms from anywhere in the world I believe.
On Twitter, SpaceX CEO Elon Musk discussed the work being done to reduce the latency on Starlink, the company's satellite internet network, to under 20 milliseconds.www.pcmag.com

forgive my ignorance on undersea cables, but dont they have repeaters all over to ensure the light source isnt degraded too much?
I mean were taking thousands of KM, and how can light stay the same "brightness" that long?
