The long distance communication system in a cellular network for higher bit rate can be designed using the various dispersion compensator like DCF , FBG and ECF as well as hybrid techniques. We have compared different Q-factors for the SMF of 50 km and 100 km with or without using fiber bragg grating as dispersion comparator . In this paper the system performance is analyzed on the basis of Q-factor , Eye diagram at different length with and without compensator . Data transmission for high speed data transmission requires more bandwidth requirement , which is an important factor for the communication system . In DWDM system , each laser must emit light at a different wavelength , with all the lasers light multiplexed together onto a single optical fiber. After being transmitted through a high-bandwidth optical fiber , the combined optical signals must be de-multiplexed at the receiving end by distributing the total optical power to each output port and then requiring that each receiver selectively recover only one wavelength by using a tunable optical filter . In this paper , by using FBG the four wave mixing effect is reduced at different value of Q-factor .
