How do the internet wires get to sea floor level? And how would they get fixed if an issue arises?
In: 88
A big ship carries VERY big internet cables that are as thick as tree trunks, it slowly lays them down on the seabed, which can take a very long time.
Average about 100kms a day that they can lay down.
When a part is damages or faulty, they can see exactly where by sending signals from 2 different shores.
They then life a piece o cable up where it’s working, and cut it, then go past the faulty part, and cut another piece off, so they have 2 working pieces, and then connect those two again with new cable.
