How to repair a broken under sea cable?
Find the location of the accident; drag the damaged part to the surface, and replace it with a new stretch of cable
May also send light pulses along the fibers in the cable to determine the exact location
A working fiber will transmit those pulses all the way across the ocean; a broken one will bounce it back
The telecom operator then sends out a large cable ship with a few miles of fresh fibre-optic lines
If the faulty part of the cable is less than about 4,000 feet down, a submersible robot can be sent The robot finds the right place; grabs hold of the cable; cuts out the malfunctioning section, and pulls the loose ends back up to the ship
Robots do not work in very deep water. In such cases, technicians use a grapnel to cut the cable and hold it
A skilled technician (jointer) splices the glass fibers; uses adhesives to attach the new section of cable
The repaired cable is then lowered back to the seabed on ropes
