I’ve been wondering about the enormity of the repair job facing the telecom companies with the screwed fiber-optic internet cables 20,000 leagues under the sea after the Taiwan earthquake – particularly how the heck they do it.

Digg pointed out a Slate story and podcast posted yesterday about exactly this. Slate’s Explainer Lindsey Goldwert says location of the broken section is the challenge, and then hoisting it up, and then replacing the damaged stretch before laying it out back down. Repairs involve light pulses, grapnels, cable ships and deep-sea robot tanks. Coolness.
