OFDM is a multi-carrier-modulation (MCM) which is deliberated as a special case of FDM technology. Single polarization fibers means that the fundamental mode propagate in only one polarization state. Single polarization Optical OFDM system is simulated with Opti-system V14.0 program. ''Coherent optical orthogonal frequency division multiplexing (CO-OFDM)'' system with different effective area and cyclic prefix length was investigated to reach high data rates with long distance by using single mode fiber (SMF). The performance of the system has been deliberated by calculating signal to noise ratio (SNR), bit error rate (BER) and optical signal to noise ratio (OSNR), it was found that as the effective area increase, the BER decreases. The optimal value is at a BER of 75*10-6 where the cyclic prefix is at 1/16 (6.25%) and the used effective area is 150 μm2.
