In this paper, analysis of CDMA network with Optical Amplifiers has
been done. As the optical amplifier provides gain as well as has nonlinear
characterstics, gain is expected due to signal
amplification as well as operation of SOAs as limiter due to gain
saturation. In this paper results have been computed for with
different SOA placements in a typical
star topology employing CDMA.
The results show that in a star topology network employing CDMA,
placement of SOAs before CDMA decoder does provide benefit due to gain as well as because of
clipping due to nonlinear gain saturation.
It is also seen that preamplifier scheme works better than
