    Optical fibers have revolutionized telecommunication, becoming the most widely used and the most efficient device for relaying information over long distances. While the market for optical fiber continues to grow, the next stage in the field of communication is the mass delivery of integrated services, such as home banking, shopping, internet services, and entertainment using video on demand/5(2). The stress properties of GeO2- and F-doped optical fibers drawn in different conditions have been investigated. The results are in excellent agreement with calculated data based on a generalized theoretical model. For constant drawing forces the influence on the stress profiles was found to be independent of drawing speed and temperature. The total observed stress is the sum of preform .

    This essential book analyzes polarization effects, including non-linear effects, and their influence in communications and sensing. You get full details on telecom system degradation caused by PMD, PDL, and PDG and techniques for mitigating it, plus insight into the effects and consequences of polarization on solitons, amplifiers, and switches. Polymer Optical Fibers summarizes research activities on polymer optical fibers to offer a complete perspective on this emerging topic. Polymer optical fibers are in great demand for the transmission and processing of optical communications compatible with the Internet, which is one of the fastest growing industries of modern times.

    optical technologies on these chips for frequency conversion [6, 7], all-optical regeneration [8,9], multiplexing and demultiplexing [], as well as for routing and switching [10,12]. The motivation for optical technologies is primarily based on the ultrahigh bandwidth of the optical fiber and the extremely low attenuation coefficient. suggested the possibility that low-loss optical fibers could be competitive with coaxial cable and metal waveguides for telecommunications applications in [2]. The commercial applications of optical fibers were not possible until when Corning Glass Work discovered an optical fiber with a loss less than the benchmark level of 10 dB/km.
