  The increasing demand on the internet trafficking to meet the demands of
video streaming and mobile communication has exerted too much pressure.
Accordingly, this demand will result in providing high bandwidth which in turn
increase the use of cells on the network. However, the current networks do not
meet the requirements of the necessary data rate. Therefore, the Dense
Wavelength Division Multiplexing (DWDM) network and the Radio over Fiber (RoF)
technology are the ideal solution for providing the necessary data rate needed
in the current networks. The DWDM, will increase the transmission distance and
will increase the data rate; nonetheless, the DWDM network will be compromised
especially by the Non-linear effects. This study in intended to propose a
system to find solutions for the issues of increasing the data rate and for
reducing the nonlinear effects. There are number of technologies that could be
adopted to fix such issues, which includes; Optical Phase Conjugation (OPC),
Semiconductor Optical Amplifier (SOA),
