There's been a lot of press about delayed approval for the Pacific Light Cable Network (PLCN) cable, which is due to connect Hong Kong, Taiwan, and the Philippines to the United States.

You can understand why this cable has gotten extra attention. Backers include Google, Facebook, and Pacific Light Data Communication (PLDC), which is owned by Chinese ISP Dr. Peng Telecom & Media Group.

I'm a cynic and you can be one, too!

This was the title of Tim Stronge's presentation during a recent webinar we did with our friends at Ciena.

Is a Mass Extinction of Submarine Cables Looming?

The rapid pace of demand growth is only going to require more international bandwidth in the coming years. While there's certainly lots of investment in new systems, cables built in the late 1990s and early 2000s continue to play a key role in global connectivity. But are their days numbered?

Happy Anniversary to the AC-1: A Twenty Year Retrospective at Subsea EMEA

Way back in 1998, a press release went out from Global Crossing about the first segment of their transatlantic fiber-optic cable.

Full city-to-city connectivity! A link between Europe and the U.S.! 

Did you catch what's so interesting about that language?
