摘要：Orthogonal frequencydivision multiplexing (OFDM) can accomplish high use effectiveness. Various system impairments affect the performance of system. So mechanisms should be adopted to improve the performance of the system. In this paper, a 40 Gbps optical OFDM system is designed. Comparative analysis of the designed system is done using different fiber standards and dispersion compensating mechanismson the basis of transmission distance and SNR. From the present research, it is clear that pre dispersion compensating mechanisms perform better than post ones.The fiber standards considered in present research are SMF, ALCATEL, ITU G.652, ITU G.654, and ITUG.655. Of all the fibers, ALCATEL (D=8 ps/nm/km)is able to cover maximum distance i.e. 660kmwithSNR 30.08 dB. For rest of fibers, the performance was remarkable for few hundreds ofkilometres and then degraded. ITU G.655(D=3.78ps/nm/km)gives the best SNR i.e. 32.08 dB upto 418km then degrades due to less DCF fiber length to compensate for dispersion.
