A different channel spacing characteristics was analysed using wavelength-division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM). In a system has 32 channels using only Single Mode Fiber (SMF) (without any amplifier or DCP) over a frequency range (100 – 400) GHz. Then compare their effectiveness, according to the distance to cover, Q factor, bit error rate (BER) and power needed, by means of advanced modulation schemes return-to-zero (RZ) in order to determine the best frequency channel. It is observed that the 100 GHz channel spacing has the maximum transmission coverage up to 90 km with acceptable power, BER and Q-factor which it is equal to 10 dB, 2.08 × e −29 and 11.19 respectively.
