AMP (Harrisburg, PA) is expanding its fiber business with the purchase of Fibernet (Melbourne, Australia), an optical-fiber-systems company. AMP is eliminating 1000 jobs in its more traditional businesses, such as the military cylindrical pin and socket connector areas, and closing at least one facility in California. . . . Mosaic Technologies (Boston, MA) and Boston University`s Center for Photonics Research have entered into a product-development agreement to build a second-generation, fiberoptic-based DNA sensor, a multiple-test version of the single-test prototype already developed (see Laser Focus World, February 1997, p. 34). . . . The Micro Switch Division of Honeywell (Freeport, IL) is combining its short-wavelength vertical-cavity surface-emitting laser technology with the long- wavelength, 1300-nm technology produced by Sumitomo Electric Lightwave Corporation (Research Triangle Park, NC) to provide optical transceivers of both wavelengths for communication equipment applications, such as asynchronous transfer mode and gigabit ethernet.
