Abstract
Optical OFDM system is considered to be the essential backbone of the next generation of ultra-high-speed networks. A dispersion effect is considered one of the common limitations in optical OFDMA system especially at very high date rate. When the pulse width reaches less than a few pico-seconds, not only the second-order but even higher-order dispersion must be taken into account. In this paper OOFDM system designed with traditional dispersion compensating devices such as Dispersion compensating fiber (DCF) used in multi spans with single mode fiber to reach to 288 km distance at 20 Gb/s. moreover, single side band (SSB) used to reduce the dispersion as well. Therefore, the overall system performance based on SNR, spectral analyzer and constellation diagram for the single side band (SSB) OOFDM system gives a good result with 16 QAM modulation.
