DWDM Meeting Bandwidths Demands
Since the Telecommunications Reform Act of 1996, the 'flood gate' has been opened for the competitive local exchange carriers to provide services throughout the world. To meet the ever changing needs of consumers, including high speed data, it has become necessary to be able to provide services on a large scale than ever before. This would mean that in order to provide quality of service you would have to have the resources to supply the demand. Data services are a crucial part of business operations. For this reason it has become essential to have fault tolerance services which could result in having to have doubled the bandwidth. This could be a big stress on an already strained infrastructure.No one could have predicted the growth that the telecommunication industry experienced. Most U.S. networks were built using estimates that calculated bandwidth use by employing concentration ratios derived from classical engineering formulas such as Poisson and Reeling. By this formula networks were designed on the assumption that a given individual would only use network bandwidth six minutes of each hour. These formulas did not factor in the amount of traffic generated by Internet access (300 percen
There are two types of fiber; single mode and multimode fiber. Modes meaning light paths in which light travels in fiber cable. Dense Wavelength Division Multiplexing is the optical technology used to increase bandwidth over existing single mode fiber optic backbones. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. To picture this, think of a single mode of fiber as a four lane highway with one lane active. Then imagine the many more cars that you can put on the highway if you open up three more lanes. That is what DWDM does. Light is a spectrum of colors, fiber optic networks reads information in the form of light which is converted to electricity later. The only range of light that fiber optics can read is infrared colors. This is due to the wavelength of those colors of light for performance. t growth per year), faxes, multiple phone lines, modems, teleconferencing, and data and video transmission. Had these factors been included, a far different estimate would have emerged. In fact, today many people use the bandwidth equivalent of 180 minutes or more each hour. One study estimated that from 1994 to 1998 the demand on the U.S. interexchange carriers'(IXCs) network would increase sevenfold, and for the U.S. local exchange carriers' (LECs) network, the demand would increase fourfold. † Noti
