Fabulous facts you didn’t know about submarine data cables

Submarine communication cables are the carriers of nearly 100 percent of all the mails, tweets, pasta recipes and other digital communications across the oceans. They connect every continent except Antarctica. They are also:

An achievement: Five attempts to lay a transatlantic cable were made over nine years—in 1857; two in 1858, 1865, and 1866—before lasting connections were finally achieved. The first official message to pass between two continents was a congratulatory note from the Queen to the President on August 16, 1858. The cable was destroyed the following month when Wildman Whitehouse applied excessive voltage to it while trying to attain faster telegraph operation. The Atlantic didn’t get broadband until 1988, when fiber-optic cable was laid across it.

Chewy: Deep-ocean cables can be 17-20 mm (0.7-0.8 in), like a garden hose. At least 40 cable faults have been caused by shark and “fish bites”, verified by the presence of fish teeth.

Entangling: Between 1877 and 1960, at least 16 whale entanglements took place with undersea cables. Today, the most common problems are anchors and trawls getting caught in the cables.

Fast: On the 1858 cable and it took 2 minutes to transmit just one character (compared to ten days for a message by ship at the time). Today, each fiber pair within a cable can carry information (including video) equivalent to 150,000,000 simultaneous phone calls. In 2008, the world’s first transatlantic transmission at 40 gigabytes per second was made between Luleå, Sweden and Manhattan over the TAT-14 cable.

File sharing for navies: The US navy didn’t mind sharing some of the Soviet Union’s information during the Cold War by tapping into USSR copper cables. According to ZDnet, today’s fiber-optic cables did occasionally prove to carry too much data for the NSA’s budget.

As you might have noted from before, we are fascinated by these high-powered garden hoses. If you know of more cool facts, please don’t hesitate to add them in the comments below.

Great, fun info – glad you shared this information here which isn’t always communicated.

Let me know if I can provide you with more information!

Now the connections are increasing. Now there are cables connection Africa to India and Europe… http://www.telecomengine.com/newsglobe/article.asp?HH_ID=AR_5001

There’s no denying that Google Chrome continues to be the darling of the web browser market. And as we predicted in July last year, Chrome overtook Firefox around November 2011.

So now the question is, when will Google also wrestle down Internet Explorer, and become the undisputed king of the browser world? In December 2011, Chrome 15 became the most popular browser in the world, beating Internet Explorer 8, but if you combine all IE versions, Microsoft still holds the number 1 spot.

Equipped with the latest web browser statistics from StatCounter, we set out to see when Chrome is likely to achieve more than 50% market share.
