Nonlinear is one of the major interferences in the RoF (radio-over-fiber) scheme. In this scheme, optical fiber transmission is an essential medium for transmitting data. Data transmission with high capacity and density is highly vulnerable to nonlinear effects. To overcome this problem, we proposed the use of HFD (high-frequency dithering) and APD (avalanche photodiode) to reduce the nonlinear effect on both sides of the transmitter and receiver sides. This study was more emphasized on SPM (self-phase modulation) and GVD (group velocity dispersion) nonlinear types. The results show that there was an increase in amplitude unit (a.u) of the APD component used on the CD. The maximum amplitude unit (a.u) generated was 500 k and the minimum was least −70 k at the optical fiber length of 10 km. Longer optical fiber length led to greater losses. Compared with the scheme without using APD on the receiving side, the results show a fivefold increase at the optical fiber length of 10 km.
