very interesting, thanks both. I'm surprised something travelling at the speed of light over a relatively short distance attenuates at all. I wonder if these amplifiers are purely optical (like mini magnifying glasses), or if they are powered (requiring running adjacent power cables)
- gus_massa 7y agoWikipedia has a lot of details about how the amplifiers work: https://en.wikipedia.org/wiki/Submarine_communications_cable#Modern_history https://en.wikipedia.org/wiki/Submarine_communications_cable...

- kitteh 7y agoPower is involved too. When I first visited a cable landing station I got to learn about the process to de-energize / energize the cable and coordinate with the ship and the remote side. Pretty involved but really neat to see. The stories are interesting too. One cable landing station on a small island the main tech would bring his family in during a typhoon to shelter there for days since it was a fairly protected site that had plenty of fuel for the generators.
