FLAG provided a link between the European end of high-density transatlantic crossings and the Asian end of the transpacific crossings. [5] FLAG includes undersea cable segments, and two terrestrial crossings. The segments can be either direct point-to-point links, or multi-point links, which are attained through branching units.
All cables presently in service use fiber optic technology. Many cables terminate in Newfoundland and Ireland, which lie on the great circle route from London, UK to New York City, US. There has been a succession of newer transatlantic cable systems. All recent systems have used fiber optic transmission, and a self-healing ring topology.
Atlantic Crossing 1 (AC-1) is an optical submarine telecommunications cable system linking the United States and three European countries. It transports speech and data traffic between the U.S., the U.K., the Netherlands and Germany. [ 1 ]
Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [ 1 ] [ 2 ] The light is a form of carrier wave that is modulated to carry information. [ 3 ]
In the 1980s, fiber-optic cables were developed. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into operation in 1988. A fiber-optic cable comprises multiple pairs of fibers. Each pair has one fiber in each direction. TAT-8 had two operational pairs and one backup pair.
Terrestrial cable may be subterranean (buried) or aerial (suspended from poles), and may be fiber or copper. [ 1 ] [ 2 ] The term "terrestrial cable" is principally used to distinguish it from submarine cable , [ 3 ] although some overlap exists between the two.
