Dispersion is one of the basic problems in the optical fiber communication. Chromatic dispersion is one of this type of dispersion. Nowadays we require high data transmission without any substantial loss in a communication system, so optical communication serves as a better choice for high data rate transmission. However it has a dispersion problem. To overcome dispersion in an optical communication system, we proposed a novel type of method to reduce chromatics dispersion in this paper. The proposed method is experimentally implemented and analysed. The eye diagram analysis test confirms achievement of complete reduction of chromatic dispersion in the fiber at long distance communication. Optisystem version 12.0.2 was used as a software tool for experimental validation of proposed method. Optical fiber system implemented in this experiment was designed for bit rate 2.5Gbps at wavelength 1550nm.

“…This effect is known as inter symbol interference. [2] Dispersion limits the information capacity at high transmission speeds. Dispersion reduces the effective bandwidth and at same time it increases the BER due to an increasing inter symbol interference.…”

Abstract:In this paper, dispersion compensating fibers (DCF) are used to compensate the positive dispersion accumulated over the length of the fiber at 10Gbits/sec and 250 km of optical fiber with 50 km of DCF. Three schemes (Pre-compensation, post-compensation and symmetrical-compensation) of dispersion compensation with DCF are proposed. The simulated transmission system has been analyzed on the basic of different parameters by using OptiSystem 7.0 simulator. The results of three dispersion compensation methods are compared in terms of four parameter, which are Q-factor, BER, Eye height and threshold value, investigated at the receiver end. Further, it has been observed that the system needs proper matching between EDFA gain and the length of the fiber for the optimum performance.

“…Among the methods on aspect of the place of DCF, we chose post-compensation. Because it has better performance compare to pre-compensation (Hu et al, 2010) (We don't have mix-compensation in one span that is implemented in our experiment). Since the GVD in SSMF is 16 ps km −1 nm and in DCF is -90 ps km −1 nm with formula (12) we can achieve the required length for DCF Eq.…”

Problem statement: Besides of some impairment that has been inherited form single channel, specialists confronted with new obstacles in WDM implementation which bared them for achieving desired performance. Although Chromatic Dispersion (CD) exists in single channel too, it can worsens new nonlinearities which are occurs just in WDM systems. So CD compensation in WDM is even more vital than single channel one. Approach: A wide range of optical and electrical CD compensation techniques have been represented. In this study we evaluate the efficiency of feed Forward-Decision Feedback Equalizer (FFE-DFE) as one type of electrical compensation methods and Dispersion Compensation Fiber as one type of optical compensator. Also we will look how electrical pulse shapes induced by pulse generator in transmitter, can impact on the performance of the either optical or electrical compensations. Results: After implementation, it was revealed that overall optical compensation with DCF gives us better performance than electrical equalizer and NRZ is more vulnerable than two other pulse shapes. Conclusion: Chromatic compensation was implemented with different pulse shapes and RZ pulse shape with optical compensation showed the best performance.
