The cable ship Global Sentinel has completed surveying Unity cable which links Japan and the United States. Unity Cable starts in Japan and terminates in Hermosa Beach, California.
The cable was completed in April 2010 and has five fiber pairs, with each fiber pair capable of carrying up to 960 Gigabits per second (Gbps). By having a high fiber count, Unity is able to offer more capacity at lower unit costs. It is said to have a capacity of up to 7.68 Tbit/s.
Unity’s installation cost around US$300 million, and its completion increased Trans-Pacific cable capacity by around 20 per cent. Google is an investor in the cable. The Unity Consortium comprises Bharti Airtel, Global Transit, Google, KDDI Corp., Pacnet, and SingTel.
With the anniversary of 9/11 less than a week away, perhaps monitoring of the infrastructure has been increased. But you wouldn’t need a cable ship for that.
