Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link Optical frequency multiplication enables the utilization of only low frequency electro-optical components at the headend. This helps to cut back the RoF system costs, while providing high-frequency operation at the RAU. Optical Frequency Multiplication employing a Fabry Parot Interferometer (FPI), is demonstrated with Optisystem for generating micro/ millimeter signals optically and distributed to many remote located base stations. The simulation results show that the relative strength and frequency of the harmonics is strongly hooked in to sweep frequency, FSR, Frequency Deviation and FM index. it's observed that optical uplifting of FM radio signals to 19, 30 and 50 GHz frequencies admire 4th, 6th and 8th harmonic after transmission in optical downlink with the facility level of 10 dbm, -10 dbm and -20 dbm respectively. Similarly, PSK data is recovered from the 4th harmonic of 12 GHz. Hence, the OFM system is employed successfully for multiple functions concurrently, like high-frequency-carrier-generation, optical signal transportation, frequency up-conversion, and bi-directional data transmission through generated harmonics.
