Do the transatlantic fibre cables have amplifiers?

They do. It's been a while since I looked into this in detail, but there's a lot of information on Google. There's some very clever stuff going on out there!

Quite a few of the places he highlights there I have visited many times. Prime ones being the Marconi site and Poldhu which has a super beach for dogs! There's one, I forget which, with a now disused(?) tiny hut to do with this stuff.

Did you get to the bit about the optical vacuum tube taking a few ms off trans-Atlantic times, with financial transactions now routing through it? (Soon after 52 mins in).

Yeah watched it all the way through, interesting about the low latency link.

Fascinating to see all of those places and cables

Yep, heís done a good job with his research. Though some of the manhole covers heís unsure of are in fact BT ones (ĎTELECOMí, ĎTELECOM HDí etc). The BT site that he says is probably disused, doesnít look like it to me, itís got an active OBASS card reader on it, would appear to be a live site. Could be for anything though.

I donít understand why he was so surprised to see a Verizon building on the industrial estate though, as heís got footage of Verizon manhole covers in the video.
