	%X This paper describes the gain and noise performances
of discrete Raman amplifier as a function of fiber lengths and the
signal input powers for different pump configurations. Simulation has
been done by using optisystem 7.0 software simulation at signal
wavelength of 1550 nm and a pump wavelength of 1450nm. The
results showed that the gain is higher in bidirectional pumping than in
counter pumping, the gain changes with increasing the fiber length
while the noise figure remain the same for short fiber lengths and the
gain saturates differently for different pumping configuration at
different fiber lengths and power levels of the signal.
