Publication date: Feb., 2012Revision A132FIBERSTANDARDSThe International Telecommunication Union (ITU-T) hasstandardized various fiber types for data networks. These aresummarized in the following table.Table 13: Fiber StandardsITU-T Standard Description ApplicationG.651 Multimode Fiber50/125-micron coreShort-reach connections in the 1300- nmor 850-nm bandG.652 Non-Dispersion-Shifted FiberSingle-mode, 9/125-micron coreLonger spans and extended reach.Optimized for operation in the 1310- nmband. but can also be used in the1550-nm bandG.652.C Low Water Peak Non-Dispersion-Shifted Fiber Single-mode,9/125-micron coreLonger spans and extended reach.Optimized for wavelength-divisionmultiplexing (WDM) transmissionacross wavelengths from 1285 to1625 nm. The zero dispersionwavelength is in the 1310-nm region.G.653 Dispersion-Shifted FiberSingle-mode, 9/125-micron coreLonger spans and extended reach.Optimized for operation in the regionfrom 1500 to 1600-nm.G.654 1550-nm Loss-Minimized FiberSingle-mode, 9/125-micron coreExtended long-haul applications.Optimized for high-power transmissionin the 1500 to 1600-nm region, with lowloss in the 1550-nm band.G.655 Non-Zero Dispersion-ShiftedFiberSingle-mode, 9/125-micron coreExtended long-haul applications.Optimized for high-power densewavelength-division multiplexing(DWDM) operation in the region from1500 to 1600-nm. |
