Submarine cable repair

Ever wonder how broken undersea cables get repaired? A few interesting links were posted to the NANOG mailing list last month, including a series of YouTube videos produced by Hibernia Atlantic onboard Global Marine's Cable Innovator. My favorite is this one demonstrating how the individual fibers are prepared and spliced together:
Other videos in the series demonstrate (in no particular order):
- Cable dropping and pick-up
- Cable molding/reinstating
- Cable wheel tension
- The cable tanks
- The test room
- The power feed room
- The rover
Interesting stuff. Alcatel also has a couple nifty Flash videos demonstrating how cables are laid and retrieved for repair.

This stuff is always fascinating to see how it's done, unfortunately I'm at work and i'm in the drawing pretty diagrams area of IT so I don't have access to the videos at the moment, look forward to watching them when I get home.

If you are curious about the process that goes into deploying a submarine cable. You can follow the one, that the company I work for is building.

Cable between egypt and tunisia has just been broken :( This kind of ship was already there to repair the damaged fiber cable , but earth moved elsewhere and they had to start again :( So France and Europe must be re routed to the US if they want to reach the whole Asia !! That must be a lot of traffic !
Thanks for the Video Stretch !

Thats pretty cool, I have often wondered why cables dont break more often on the bottom of the ocean. My imagination certainly thinks the bottom of the ocean is a much more horrible place then it probably is. Guess I have seen Abyss and Leviethan too many times.
Watching that first video I couldnt help but think "how many sailors does it take to splice one piece of fiber together?" :p

Where can I get a map of the internet links with some detail? I would like to have a worldmap of the real internet links including sat links to know how my packets travel around the world. It would be great to know more about this ..is so virtual for us..

Kevin, check out this link
Not entirely sure if this is every cable but its the only decent source I've come accross. Maybe someone has a better source?
