AT&T succeeds in system test of fiber optics
Article Abstract:
AT and T Bell Laboratories and Kokusai Denshin Denwa (KDD) Co test a new fiber-optic system. For the test, AT and T researchers linked a system consisting of 2,790 miles of cabling and signal regeneration equipment with a similar 2,790 mile system from KDD. The two systems' combined 5,580 total mileage is about equal to the longest trans-Pacific cable extension. The test results show that the new optically amplified system will be able to carry 600,000 phone calls simultaneously across the Pacific Ocean. The system consists of strands of fiber coated with erbium, a rare earth element. At intervals, the strands are spliced to the system's standard glass fiber. The fiber strands, in essence, act as the system's signal amplifiers.

Communications meeting focuses on fiber optics
Article Abstract:
The 1990 International Switching Symposium (ISS), held in Stockholm, Sweden, focuses on fiber-optic communications and intelligent computer networks. Optical switches and network management systems are expected to revolutionize the public telephone network over the next ten years. Public telephone companies are expected to better integrate the disparate communications technologies to accommodate the vast amount of information that will be transferred over future fiber optics and public networks. Intelligent computer networks, a technology that will enable telephone companies to allow third-party suppliers to send their programs to customers on a dial-up basis, is another focus of the conference.
