FIRST LASER PHONE CALL ZIPS ACROSS THE ATLANTIC!
ISAAC ASIMOV DEDICATES TAT-8; MAKES FIRST CALL
------------------------------------------------
A shark-proof undersea cable began carrying laser beam phone calls across
the Atlantic Ocean Wednesday as the first leg of a network designed to
revolutionize service on three continents.
AT&T, British Telecom and France Telecom, the three principal owners of
the cable asked well known author Isaac Asimov to dedicate the new cable
and place the first call.
In his remarks, Asimov said, "Welcome everyone to this
historic trans-Atlantic crossing -- this maiden voyage across the sea
on a beam of light..." He noted, "...our world has grown small, and
this cable, which can carry 40,000 calls at one time is a sign of the
voracious demand for communications today....... .....the clarity is
in striking contrast to the crackling first telephone message from
Alex Bell to his assistant Thomas A. Watson 113 years ago..."
Mr. Asimov was the first speaker of several in a video
conference in New York that was transmitted to Paris and London by the
new cable.
The fiber-optic cable, which is thinner than a child's wrist,
is able to handle double the capacity of all the trans-Atlantic
copper-cable predecessors combined. It took seven years to design,
build and install. The total cost was $361 million, but the people
involved insist that in the long run, it will mean a continued decline
in the price of overseas phone calls.
Ordinary television broadcasts will continue to be carried by
satellite because they would take up too much room on TAT-8. But the
cable will be used for video conferences on a regular basis between
the United States and Europe, using a method to compress the signals
and take up very little bandwidth.
American Telephone & Telegraph Company, which will operate
TAT-8, said 1988 is the first year it will handle more than one
billion international calls.
Commenting on Asimov's remarks of '...a voracious demand for
communications..' an AT&T spokesperson noted that even this new cable
will start running out of room late in 1991. The fourth quarter, 1991
is when a new fiber-optic cable with nearly double the new cable's
capacity is scheduled to begin operation.
Fiber-optic service to Japan and the far east will start in
the second quarter of 1989 under the name PTAT, and fiber-optic links
to the Caribbean and the Mediterranean will open in 1991 or 1992.
Lasers have revolutionized phone networks by making it
possible to transmit information in the form of rapid pulses of laser
light through hair thin strands of glass. The lasers transmit
information in digital form coded into a series of ones and zeros.
Most long distance calls within the United States are already carried
on optic fibers.
Ownership of TAT-8 is as follows --
American Telephone and Telegraph, 34 percent
British Telecommunications , 15.5 percent
France Telecom , 10 percent
The remaining 40.5 percent is divided among 26 partners, some of whom
own up to two percent interest; while others own less than one percent
interest. The principal partners are --
Sprint Communications, MCI, Western Union and Northern Telecom.
Will overseas telephone rates go down in the next few years? AT&T says
they will. The exact amount is anyone's guess, but a spokesperson from
AT&T said "....I think within a few years the rates will be *less than
half* of what they are now..."
Wednesday, December 14, 1988: An historic day in telecommunications
history, and one I believe is only third to the invention of the
telephone itself; the second most historic occasion being the
completion of the cable which connected the east and west coasts of
the United States in the early 1920's.
