Abstract :
The CO-OFDM (coherent optical orthogonal frequency division multiplexing) system is simulated and studied in the paper. The electro-optic modulation and photoelectric detection in CO-OFDM are studied. The performance of CO-OFDM system with different modulation mode and different number of sub-carrier are studied. The result of simulation shows that performance depends on the modulation mode, coupling optical power, attention of atmosphere, the number of the subcarrier and OSNR. The result of simulation also show that the CO-OFDM system will has good anti-dispersion ability and higher bandwidth efficiency if using the suitable modulation and coupled combined optical power.
