Tonga undersea cable may take at least month to repair
A key undersea cable that was destroyed in a volcano eruption in Tonga may take at least four weeks to be repaired, said New Zealand’s foreign ministry. The cable was severed during a volcanic eruption on Saturday, crippling communications and cutting the Pacific island off from the outside world.
Fixing a break in a fibre-optic cable on land is easy for an experienced technician, but repairing a cut in one on a seabed is far more complicated. Cable operators must first locate the fault by seeing how far a pulse of light travels down the cable before it bounces back at the break.
A repair ship is currently en route from neighbouring Papua New Guinea. Meanwhile, efforts to establish a temporary broadband satellite link for Tonga appeared stalled.
