In this paper, an effort is made to analyze the
integration of direct detection optical orthogonal frequency division multiplexing
(DDO-OFDM) with wavelength division multiplexing (WDM) to reach high data rates
of 1.050 Tb/s over 3600 km single mode fiber (SMF). The 1.050Tb/s signal is generated by multiplexing 30
OFDM signals with 35 Gb/s for each OFDM. The performance of the system is
studied by measuring the optical signal to noise ratio (OSNR) of each WDM
channel; signal to noise ratio (SNR); and bit error rate (BER); while analyzing
the constellation diagram of all users. Also, the relationship between the OSNR
and BER is studied and it is noticed that as the OSNR increased, the BER
decreased. As can be seen form the results, as the
transmission distance increased the BER increases and to keep the BER less than
10-3 we need to increase the OSNR.
