Corning, Gore and Siecor Demonstrate Capability of Next Generation Multimode Fiber at 1 and 10 Gigabits Per Second
CORNING, N.Y., Jan. 17 /PRNewswire/ -- Corning Incorporated (NYSE: GLW), W.L. Gore & Associates, Inc., and Siecor announced today the results of further testing of cabled Corning(R) next generation prototype multimode fiber. Successful demonstration of serial transmission at both 1 and 10 gigabits per second (Gb/s) was achieved with Corning(R) multimode fiber using Gore's high-speed 850nm vertical cavity surface emitting laser (VCSEL) technology. The fiber, best suited for high-speed transmission at Gigabit Ethernet (GbE) speeds or higher, is a prototype 50?m InfiniCor(TM) fiber optimized for 850nm operation. In August 1999, Corning and Gore achieved an industry first -- 600 meter serial transmission at 10 Gb/s over Corning(R) multimode fiber using a Gore VCSEL. Utilizing the knowledge gained from this and other testing, Corning can now produce a robust, highly repeatable enhanced short wavelength optimized fiber that is ideal for GbE as well as 10 Gb/s. This next-generation fiber prototype transmitted 2000 meters at GbE speeds, as well as maintaining error-free transmission at 10 Gb/s for 500 meters. To better simulate real world system conditions, the fiber was cabled by Siecor and multiple connectors were used in each experiment. The 850nm VSCEL was coupled to the fiber and the output pulses, converted into electrical pulses, displayed the bit pattern on the oscilloscope in the form of an eye diagram. The eye diagrams illustrated a very clear, well open-eye for both 1 and 10 Gb/s modulation. "We have selected the link lengths for this prototype fiber to reflect realistic premises applications. According to a recent IEEE survey, 500 meters at 10 gigabits per second covers 98% of in-building backbones in the premises market." says Carolyn Case, Corning's premises product line manager. "The 2000 meters at GbE encompasses the limit of a multimode fiber campus backbone according to the Commercial Building Telecommunications Cabling Standard (TIA/EIA-568-A)." "We have gained a lot more knowledge about the expectations and capability of multimode fiber from these recent tests," says Bob Pollock, manager of market strategy for private networks at Siecor. "There is a big difference between testing bare fiber and cabled fiber with connectors. These tests show that optimized fiber and high data rate VCSELs will work in installed networks. The bottom line for end users is that cost-effective, high-speed local area networks are becoming a reality -- with the help of 850nm technology." According to Dave Welch, business leader at Gore, "The use of 850nm VCSELs with laser-optimized, multimode fiber will enable a cost-effective transition to higher speed LANs. Gore is collaborating with leading optical fiber and cable manufacturers like Corning and Siecor to develop low cost VCSELs that will support 10 Gb/s transmission."
