All forms of dispersion degrade a light wave signal, reducing the data carrying capacity through pulse-broadening. Chromatic dispersion results from a variation in propagation delay with wavelength, and is affected by Fiber materials and dimensions. In this paper we briefly review limitation imposed by chromatic dispersion on optical fiber system. We have presented idea about how to design fiber optics system using dispersion compensated fiber to reduce chromatic dispersion. We are providing mathematical design for optical fiber system to reduce chromatic dispersion with bit rate 2.5 Gbps, for wavelength 1550 nm. The use of dispersion compensating fibers (DCF's) has now emerged as the most practical technique to compensate for the chromatic dispersion in the long-haul, optically amplified Standard fiber. © 2010 Springer-Verlag Berlin Heidelberg.

The first successful long distance public message was sent by Samuel Morse on a 61 km telegraphic line and this simple act has led to huge advancement in telecommunication field. With the increase in number of users using circuit switched and packet switched networks, fraudulent calls and data usage is also increasing proportionally. To avoid this false usage of the advanced network, interception is done. All the international long distance calls go through ILD MGW. In the traditional telephone networks, implementation of LIM was easy due to provision of centralized networks but with the increase in the IP users this task became stale. This paper describes the LIM deployment at the ATCA MGC and its various advantages. © Research India Publications. Source
