Corning InfiniCor(TM) 50 micron Multimode Fiber Demonstrates Over 3000 Meters at Gigabit Ethernet

Aug 23, 1999, 01:00 ET from Corning Incorporated

    CORNING, N.Y., Aug. 23 /PRNewswire/ -- Corning Incorporated (NYSE:   GLW)
 announced today that InfiniCor multimode fiber achieved over 3000 meter
 transmission at Gigabit Ethernet speeds in the 850nm window.  This
 demonstration of Corning(R) 850nm optimized InfiniCor 50 micron fiber greatly
 exceeds any test ever performed for Gigabit Ethernet multimode systems.
     Measurements at Corning's Center for Fiber Testing (CFT) were performed on
 the premises system test bed.  This set up is designed to replicate actual
 field installations and includes commercially available fiber optic
 transceivers, connector patch panels, and jumpers.  The heart of the test
 equipment is a state-of-the-art HP bit error rate tester and a high-speed
 signal communications analyzer for eye diagram analysis.  In this test, the
 output signal clearly illustrated an open-eye diagram, demonstrating error
 free transmission.  CFT, the world's first optical fiber test facility,
 offers more than 60 different tests and is a leading resource for qualifying
 new product innovations and troubleshooting customer issues.
     "Our cablers and end users alike continue to tell us they want a low-cost,
 long term solution for local area networks," said Windsor Thomas, Corning's
 premises product line manager.  "Multimode fiber is a superior value solution,
 poised for growth.  When criteria are defined for 10 Gigabit Ethernet, Corning
 will lead the industry with the next generation of multimode fiber.  Until
 then, we set the industry benchmark for serial transmission at Gigabit
 Ethernet over multimode fiber."
     InfiniCor fiber is tailored for installation in premises applications
 including the campus backbone, building riser and horizontal deployment.
 Typical applications are local area and campus-wide networks carrying data,
 voice, and/or video services using light emitting diodes, 850nm vertical
 cavity surface emitting lasers (VCSELSs), 780nm CD lasers, and
 1300 Fabry-Perot lasers.
