Tanzania Fiber Optics

In fiber-optic communications, Coarse Wavelength Division Multiplexing (CWDM), a WDM technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. Effective CWDM realizations with uncooled lasers and wide passband filters a nominal central wavelength spacing of not less than 20nm. Total source wavelength variation of the order of ± 6-7nm is expected to be compatible with current filter technologies. In 2002 the ITU standardized a channel spacing grid for use with CWDM (ITU-T G.694.2), using the wavelengths from 1270nm through 1610nm with a channel spacing of 20nm. Many CWDM wavelengths below 1470nm are considered "unusable" on older G.652 (dotten line) specification fibers, due to the increased attenuation in the 1270–1470nm bands. Newer fibers which conform to the G.652.C and G.652.D (full line) standards, such as Corning Single mode Fiber-28e and Samsung Widepass nearly eliminate the "water peak" attenuation peak and allow for full operation of all 18 ITU CWDM channels in metropolitan networks.
