Coming invents first ) low-loss optical fiber

Corning invents ) va por deposition for fiber manufacturing

In the race to satisfy the global demand for telecommunications bandwidth, the need for technically advanced, high-capacity networks is paramount. Since 1998, the world has relied on Corning® LEAF® optical fiber to transmit information at higher bit rates and over longer distances than ever before. Corning LEAF optical fiber is:

* The world's first large effective area, non-zero dispersion-shifted fiber (NZ-DSF)

* Optimized for long-haul and high-data-rate metro networks

_* The world's most widely deployed NZ-DSF

* The industry leader in polarization mode dispersion (PMD) specifications, enabling evolution from today's 10 Gb/s networks to the 40 Gb/s systems of the future

_* The world's first low-water-peak NZ-DSF

* In compliance with the industry's most stringent requirements, including:

• ITU-T G.655 (Tables A, B, C, D)

• IEC Specifications 60793-2-50 Type B4

• TIA/EIA 492-EA00

• Telcordia's GR-20

Corning sets world record )-for low attenuation in laboratory tests

Corning introduces first )-dispersion-shifted fiber
