| Abstract This paper provide a software simulation to enhancement performance system using hybrid Erbium doped fiber amplifier/Raman amplifier (EDFA/RA), by the way, RA provides a continuous amplification along the fiber. The (8 × 10Gb/s) wavelength division multiplexing (WDM) system show successful transmitter work at (193.1 to 193.8 THz) all input channels have the same power with (-6.66dBm) these signal are amplified through EDFA and RA of (20km), two pump laser used. The total output signal is (29.36dBm), total output noise is (- 13.53dBm), and output optical-signal-to-noise ratio (OSNR) is (0dB). The average maximum Q-factor for all 8- channels is (4.79), and the average of minimum BER is(3 × 10 ), this mean the optical network is exploiting for high speed network communication with low error rate, and the major contribution is the development of the multi-destination communication over the lightwave WDM system. The system is simulated, tested, and verified using OptiSystem Software Package | ||
