Optical Orthogonal Frequency Division Multiplexing (O-OFDM) provides major advantages in mitigating Group-Velocity Dispersion (GVD) in Single-Mode Fiber (SMF). Unfortunately, substantial dispersion is accumulated in long-haul transmission, leading to a longer Cyclic Prefix (CP). This effect sets some limitations on the overall throughput and the spectral efficiency. On the other hand, if the CP length...
The Performance of Orthogonal Frequency Division Multiplexing (OFDM) combined with Quadrature Amplitude Modulation (QAM) has been analyzed in presence of fiber optic dispersion. The influence of dispersion on the (OFDM) spectrum is investigated with fiber lengths, bit rates, no. of channels and source line widths. The inter-channel interference occurs due to dispersion-induced broadening of OFDM spectrum...
