For the expansion of the linear dynamic range of Radio over Fiber(ROF) communication systems
this paper summarizes the advances in the relevant study in China and abroad and sorts out and expounds the constraints on the system dynamic range.It focuses on a dispersion-immunized highly linear modulation technology
which is based on the dual parallel Mach-Zehnder modulator structure and pre-distortion idea.Experiments verify the correctness of the principle and the optimum experimental conditions and prove that the new technology improves the dynamic range measuring value of ROF communication systems by at least 20 dB over conventional ROF systems in 25 km single-mode fiber transmission.
