Russian scientists for A.T.&T. and Corning

Article Abstract:

AT&T Bell Laboratories and Corning Inc each sign agreements by which they hire the services of Russian scientists for research into fiber optics. Fiber optic cables can carry television signals, conversations and computer data at far greater speeds than traditional copper wiring. The technology is currently too expensive, however, for broad-based use. Russia's sophisticated scientific research laboratories are focusing on the development of ultra-high strength fiber optic cables and coatings that will decrease the loss of tensile strength caused by exposure to moisture in the air. AT&T has agreed to hire about 100 scientists from Moscow's Russian Academy of Sciences. Corning's agreement is with 115 researchers from the Vavilov State Optical Institute of St. Petersburg. The scientists will be paid at their current wages of about $40 a month, and will retain patent rights to their research within Russia.

TV by telephone: long way to go

Article Abstract:

GTE Corp is testing a videotex system that provides the viewer with a television programming via telephone lines. With this system, viewers can select programs via a remote control. The prototype system also includes a video camera for supporting picture-phone services. The systems represents a move by telecommunications companies toward digital services. An FCC ruling has stated that telephone companies may offer video services over telephone lines. Cable television companies have been fighting to prevent relaxation of regulations that previously prevented telephone companies from offering information services over telephone channels. Telephone companies, however, need to implement more fiber optic cabling in order to offer video, data and voice transmission because traditional copper wire cannot carry the amount of information needed for video signals.

Laser benefits now closer to home

Article Abstract:

AT&T and Northern Telecom Ltd announce separate innovations in fiber-optic technology that could help increase the number of calls routed through telephone lines and could reduce costs. AT&T has developed a way to transmit 6.8 billion bits of information a second on a glass strand. This could allow up to 100,000 calls, and helps the system work over distances up to 520 miles away. The Northern Telecom research found a way to cut the cost of installing a part of the fiber-optic technology, which currently consumes up to $3,000 per household. Laser light has different characteristics from normal light. and sends approximately 1.7 billion bits of information per second. The construction of a transmission module used to cost $500 but now may reduced to just $50.
