10 minutes of 4k video is ~30GB.

Knowing the size of a video file is exactly not the information, that would help me put this number in a meaningful perspective with any comparable operation. How do I think of 42 petabytes in terms of an ISP? Is that a lot? How does it compare to other satellite providers? How does it compare to 4G capacities? Is this a small country worth of traffic or just any ol' data center? I have no intuition about traffic at…

42 million gigabytes per day, or if we are working with 30GB for 10min of 4k movies - 233,000 hours of ultra HD movies per day

Over estimating by a factor of 86,400.

I have absolutely no idea how that number relates to any comparable operation. Can anyone add a banana for scale?

I feel like this is a bad example.

Most people's experience with 4K video is through a streaming service, and 10 minutes of 4K video on a streaming service is more like 1-1.5 GB.

Or a UHD Disc perhaps where 10 minutes is 3.5-7 GB.

> If you took a petabyte's worth of 1GB flash drives and lined them up end to end, they would stretch over 92 football fields. https://info.cobaltiron.com/blog/petabyte-how-much-informati...

That's actually a somewhat useful visual.

Bangladesh, the whole country, usage 2,300Gbps as of 2021. So 1 Petabyte per hour?

Edit: It's international traffic. YouTube, Facebook video has local cache server by ISP.

I still dont think this is what the OP was asking for. This is in the context of an individual-HD video is an individual perspective. More helpful would be a comparison to say a small town or a major city or state.

The speed of light in a vacuum is roughly 50% higher than the speed of light in fiber.

Is attenuation in a vacuum also better?

yes, glass has a non zero amount of absorption which is why Erbium amplification is required.
