TeleGeography released a 2013 version of its Submarine Cable Map on Thursday showing the 232 cables that ferry telecommunications under water between countries. The mapmakers note that the number of cables do not denote capacity, but present an interesting visual of otherwise unseen connections around the world.

In addition to mapping the locations of the cables, the map shows a chart detailing the names and connectivity of all the cables installed between 1997 and 2012. For instance, the Challenger-Bermuda 1, built by Alcatel-Lucent in 2008, connects the US to Bermuda and had an initial capacity of 20 Gigabits per second, scalable to 320 Gigabits per second. The Unity/EAC-Pacific cable, lit in 2010 and funded in part by Google, connects the US and Japan (and cost around $300 million to build, according to Wired).

In addition to the two larger charts, the map also includes insets that show network latency between countries over their undersea cables. Worst connections: Japan to the UK, the US to South Africa, Brazil to almost everywhere. A second inset shows rough estimations of how heavy transmissions are between countries with the thickness of lines: transatlantic communications are unsurprisingly heavy. Cables from India to Africa also handle a significant amount of traffic.

Twelve more of the cables shown on the map are set to be strung between landmasses during the coming year. Two cables on the docket: Port Vila to Fiji, and Fiji to Tonga. The lower chart shows that cables from Europe to sub-Saharan Africa are also on the rise.

The map is available as a print as well as an interactive version online.
