AT&T laser chips conduct heat via synthetic diamond

Article Abstract:

AT&T announced that it is developing laser chips that use synthetic diamond to conduct heat, and the company also said that its new microprocessor, the Hobbit, is available for sale. The Hobbit, which costs $35 for 10,000 processors, or less than $100 for the chip set, is touted as containing five times the processing power of Intel Corp's 80486 chip, and will be able to operate with battery-powered pocket communicators. The chips with the new heat conductors are expected to be available in late 1993. They are made with a new technology that mixes chemically vapor-deposited (CVD) diamond films with an unspecified metal. According to AT&T, the new material conducts heat better than aluminum nitride, silicon carbide or beryllium oxide by as much as five or six times. AT&T has yet to choose a synthetic diamond supplier, although it is negotiating contracts with several companies.

AT&T to unveil alliances creating a global network

Article Abstract:

AT and T plans to announce a joint venture with carriers in Australia, Japan, Singapore and possibly Germany, France, Belgium and elsewhere that could turn the company's long-distance system into a global network. The venture will use a special signaling network to manage all voice and data communications of AT and T corporate customers in the US, Europe, Asia and Australia. Reportedly, AT and T will invest hundreds of millions of dollars in the venture, which could pose a severe threat by British Telecommunications PLC and MCI Communications Corp to construct their own global networks. AT and T's new partners would automatically become players on the international stage.
