spreading of a light pulse as it travels down a fiber when light pulses launched close together(high data rates) spread too much and result in errors and a loss of information. The spectral width determines the number of different wavelengths that are emitted from LED or laser. One way to reduce chromatic dispersion is to narrow the spectral width of the transmitter. Chromatic dispersion can be compensated for with the use of dispersion-shifted fiber (DSF). Laser has a more narrow spectral width

Advantages and Disadvantages of Fiber Optics An optical fiber is a thin and flexible fiber that carries the light between the two ends of the fiber. Optical fibers are widely used in Fiber Optic Communications‚ which is the transmission over longer distances at higher bandwidths than other communications. A fiber optic communication system consists of three components: an optical transmitter‚ a fiber optic cable‚ and an optical receiver. The optical transmitter converts electrical signal to

Chapter II Review of Related Literature Chemical Wood Pulping Chemical wood pulping involves the extraction of cellulose from wood by dissolving the lignin that binds the cellulose fibers together. The 4 processes principally used in chemical pulping are kraft‚ sulfite‚ neutral sulfite semichemical (NSSC)‚ and soda. The first 3 display the greatest potential for causing air pollution. The kraft process alone accounts for over 80 percent of the chemical pulp produced in the United States
