How will they fix the submarine wires from the quake?
 

I wonder how they do it exactly and how long it will take after the quake near Taiwan. If you don't know what I'm talking about then here you go.

I would guess that they will probably raise the cable off the floor, splice in a good section, then let it drop.

Let's hope they don't.. I like not having any chinese traffic.

I don't know, but that would blow!

i don't have any idea on how long will it take to fix that problem...
Let us just pray for easier results..:thumbsup :thumbsup

Sounds logical

20+ years in the biz helps

old school cable, yes . . . fiber, not so much

Things only engineering experts know. Let's just hope they could fix those cables as soon as possible. :pimp

Exactly. They essentially run big hooks on the ocean floor until they snag them and then raise them and fix them.

I remember seeing something on TLC or some channel like that aout how they do it.

They use sonar to find the cable, then use an rov to uncover it and hook something on, and then pull it up into a clean room in the ship.
Was pretty neat.

2-3 weeks they are saying....

Send out a ship, power the cable down, cut the cable, grab one end and pull it up, buoy it off, grab the other end, splice it to a new cable section, recover the other end, splice at that end, test and drop. The splicing generally can be fusion splicing where the fibre is accurately aligned and actually melted until it flows together (~ 0.03dB loss) or a mechanical splice where the ends are effectively clamped together (~ 0.3dB loss). Not sure which they use nowadays at sea for repair.

there often isn't a 'lot' of slack - the above method ends up inserting some new cable and hence the initial cut. The strain of pulling up the uncut cable would probably break it anyway
