Corning Introduces New Ultra-Low-Loss, Single-Mode Optical Fiber for Long-Haul and Regional Networks.CORNING, N.Y. -- Corning Incorporated Corning Incorporated NYSE: GLW is an American manufacturer of glass, ceramics and related materials, primarily for industrial and scientific applications. The company was known until 1989 as Corning Glass Works. (NYSE NYSE See: New York Stock Exchange : GLW GLW Glasgow Airport (UK) GLW Gross Laden Weight GLW Good Lady Wife (Australia) ) today unveiled a new single-mode optical fiber In fiber-optic communication, a single-mode optical fiber (SMF) is an optical fiber designed to carry only a single ray of light (mode). This ray of light often contains a variety of different wavelengths. with Corning([R]) ultra-low-loss technology. This fiber has world-class specifications for low attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. and low polarization mode dispersion Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. (PMD (Polarization Mode Dispersion) The type of dispersion that occurs in singlemode fiber due to a lack of perfect symmetry in the fiber and from external pressures on the cable. Light travels over singlemode fiber in two polarization states. ), enabling greater system reach and longer span lengths in long-haul and regional terrestrial networks. This fiber, fully compatible with the installed base of single-mode fibers, has the lowest loss of any terrestrial-grade fiber with maximum attenuation available between 0.17 and 0.18 dB/km at 1550 nm. Additionally, the fiber has the lowest PMD of any ITU-T See ITU. ITU-T - International Telecommunications Union G.652 compliant optical fiber featuring a en 0.04 ps/eUkm PMDQ link design specification. Combined, these features provide spare network margin that can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility or lengthen the distance between regenerators. "Extended fiber reach brings significant value to our carrier customers and is especially useful in constructing and planning new networks which must span difficult terrain," said Eric Musser, senior vice president and general manager, Corning Optical Fiber. "With Corning ultra-low-loss fiber technology, the world's network operators will have flexible design options that can result in significant cost savings upon installation and over the lifetime of the network." Corning is the first optical fiber manufacturer to offer this unique combination of ultra-low attenuation levels and low PMD levels in a G.652-compliant product. This is the second Corning optical fiber product to be commercialized featuring Corning ultra-low-loss fiber technology. Corning introduced a submarine product, Vascade([R]) EX1000 fiber, with ultra-low-loss technology in 2006. Corning's new terrestrial single-mode fiber with ultra-low-loss technology will premiere March 27-29 at the OFC/NFOEC 2007 conference in Anaheim, Calif.
