ABSTRACT: OFDM (Optical
Orthogonal Frequency Division Multiplexing) in the optical domain is a
promising technology which provides solutions to problems of today’s optical
networks. In the present research an optical OFDM system is designed using different modulation techniques QPSK (quadrature
phase shift keying), QAM (quadrature amplitude Modulation). Various signal conditioning parameters, like OSNR (optical
signal to noise ratio), BER (bit error rate), chromatic dispersion and
electrical SNR (signal to noise ratio) have been reported in present research. These
parameters could be used for identifying the fault. On the basis of
conclusion drawn for values of these parameters, the system may dynamically
adapt and reconfigure itself for better transmission. In present research
OPTSIM and MATLAB has been used as Simulation tools.
