The different cables often have different landing points. In the USA these are spread along the eastern seaboard, while in Europe they are typically in Brittany, the West of England, and in Northern Germany. Today TAT-8 through TAT-12/13 are all in service. The typical price for a complete system (cables, repeaters, equipment at the landing points, all marine operations) is about 600 M$.
TAT-8 connects Tuckerton NJ to England and France and has offered (2+1)*280 Mbps PDH capacity since it came into operation in 1988. [The convention (2+1)*280 used here to describe the capacity indicates that two fibre pairs with a capacity of 280 Mbps each are available to provide the normal service, while another fibre pair with similar capacity is available for back-up purposes. The text inside these square brackets should be a footnote, but the .html version of the paper seems to lose footnotes, which is why it is inelegantly placed here]. In the initial forecasts made by the TAT-8 consortium it was expected that the cable capacity would be filled by the year 2000, but it was actually filled in 1990, six times faster than foreseen.
