I know there are many of these cables that have been around for years, but I am curious how are they physically secured? Especially where they transit from ocean to land? Is there some long underground/sea tunnel of conduit that the cable is routed through to the basement of some building? Or if you are walking along the beach somewhere is there just some cable running out of the ocean along the beach to some buildin…

I'll take any chance I can get to link to this wonderfully sprawling 1996 article from novelist Neal Stephenson about the laying and landing of transoceanic cables: https://www.wired.com/1996/12/ffglass/

Yes it's long, but it's so worth it!

I know a lot is focusing on the Bandwidth. But are we making any progress on Long Distance Subsea Cable using Hollow Core Cable, achieving close to maximum speed of light for theoretical lowest latency possible? Imagine cutting latency from West Coast US to Hong Kong by 50ms! Light is only traveling at around 2/3 of speed within Fibre. The previous decades have been around Bandwidth. Is time we shift out focus to lat…

You gotta bore for that sweet latency win. A chord tunnel between San Francisco and Hong Kong would save 1300 miles (20% improvement right there), and if you drill it straight enough, you won't even need a cable.

More feasible would be transmitting neutrinos or some other signal that would not be blocked by the Earth.

Alameda enterprises excited by rumours of new chord tunnel Thursday, low latency burrito delivery futures up 5%.

And they are heated along the way!

Wow, talk about a barrier to entry. Google already has Curie from North America to South America and Equiano from Portugal to South Africa. They're also working on Hopper from North America to UK and Spain: https://cloud.google.com/blog/products/infrastructure/announ... I presume that the other trillion-dollar companies are getting in on the action too.

Welcome to the new form of Colonialism!!

Source, destination, message length, etc. Lots of interesting meta data to play with.

assuming there isn't a point-to-point encryption layer for the whole cable.

Sure, but the NSA tap probably sits just after that point.

This is super-cool! I found "enough to transmit the entire digitized Library of Congress three times every second" to be a really weird comparison though - I'm used to text being really small and compressible, and I doubt many people have an intuitive grasp of how much One Scanned Library of Congress is. How many hour-long Netflix/YouTube episodes per second, on the other hand...

How long to transfer all of Youtube? ;)

> More feasible

If they don't interact with the thousands of miles of earth between the source and the destination, they probably also won't interact with the receiver! :p Imagine the retransmission rates!

War and Peace is a few MB. A “YouTuber” gossiping in HD is more bits. Luckily video services rely heavily on on-net caches.

Please don't give the HFT's ideas, they'll probably do it and cause a half dozen tsunamis in the process.
