Abstract
Abstract Dispersion is one of the very important parameters that effect on the performance of optical fiber communication systems. It causes pulse broadening, limiting of transmission distance and low bit rate. Dispersion compensation fiber (DCF) is widespread used in the dispersion compensation scheme. In this paper, the suggested DCF included (pre–post-symmetrical) schemes with various bit rates (10–60 Gbit/s), and the positive dispersion accumulated over the length of the fiber at 100 km of optical fiber with 21.25 km of DCF. Optisystem software version 7 is used to design simulation model. The performances have been compared on the basis of parameters such as Q factor, bit error rate (BER) and eye height which used to evaluate the performance analysis of the system. We concluded that the symmetrical compensation techniques are better than the other compensation schemes when the Q factor is 14.9536 and BER is 1.759842.10−0.22, these at 60 Gbit/s and the input cw laser frequency equal 193.1 THz.
