Year or range of years in which the achievement occurred:
1988
Title of the proposed milestone:
Trans-Atlantic Telephone Fiber-optic Submarine Cable (TAT-8), 1988
Plaque citation summarizing the achievement and its significance:
TAT-8, the first fiber-optic cable to cross an ocean, entered service on 14 December 1988. AT&T, British Telecom and France Telecom led the consortium that built TAT-8, which covered a seabed distance of 5846 Km. between North America and Europe. AT&T Bell Laboratories developed the foundational technologies: 1.3 micron fiber, cable, splicing, laser detector, and 280 Mbps repeater for 40,000 telephone-call capacity, and led the integration at Freehold, NJ.
In what IEEE section(s) does it reside?
IEEE NJ Coast Section

Street address(es) and GPS coordinates of the intended milestone plaque site(s):
AT&T Labs, 200 S Laurel Ave., Middletown, NJ 07748
Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.
Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need.
This is the main AT&T Labs Building in New Jersey, in the vicinity of Tuckerton, NJ (cable landing site) and Freehold, NJ (technology integration site). There is a mounted bust of Alexander Graham Bell in the vicinity of where the plaque will be installed.
Are the original buildings extant?
YES, this building is operational and used as labs facility housing nearly 5000 employees.
Details of the plaque mounting:
Ground Floor Entrance Hall Lobby
How is the site protected/secured, and in what ways is it accessible to the public?
The site is within the security perimeter of AT&T.
Who is the present owner of the site(s)?
AT&T

What is the historical significance of the work (its technological, scientific, or social importance)?
See URL - http://www.ieeeghn.org/wiki/index.php/Oral-History:Jack_Sipress TAT-8 was the first transatlantic cable to use optical fibers, a revolution in telecommunications. It had a capacity equivalent to 40,000 telephone circuits which was ten times the capacity of the last copper cable. Several new technologies had to be developed which were beyond those for land applications: (a) strong enough fiber strand and undersea cable that required ten times the strength available with typical fibers of that time; (b) strong splicing to withstand the rigors of the ocean as well as the laying of cable or pull up and repair of the cable at the fault location; (c) 1.3 micron wavelength single mode fiber and matching lasers and detector technology; (d) silicon for repeaters running at 280 Mbps and with very low failure rates. These resulted in far fewer repeaters and thinner cable than the copper submarine cable.
What obstacles (technical, political, geographic) needed to be overcome?
See URL - http://www.ieeeghn.org/wiki/index.php/Oral-History:Jack_Sipress The regulatory agency, Federal Communications Commission, was promoting satellite technologies for across the ocean applications and would not let Bell System to put in new cables. The new fiber-optic submarine systems had to be developed rapidly, and implemented in a span of seven years.
What features set this work apart from similar achievements?
This was the first submarine fiber-optic cable system and several new technologies were developed rapidly for this purpose. The lessons learned were incorporated in later systems such as submarine cable systems across the pacific and around the world. Later terabit fiber-optic submarine systems that make the internet of today possible build on this strong foundation.
References to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or citations to pages in scholarly books. At least one of the references must be from a scholarly book or journal article.
