Millimeter-waves have found wide application in various fields. In this research, MMW generation, transmitting and receiving, multiplexing techniques are investigated. Three ways of MMW generation based on photonics are discussed. By modeling these three techniques and applying different situations of transmission links up to 100 km and fixed bit rate of 2.5 Gb/s, different results were found and compared to each other. Also, the effect of chromatic dispersion is discussed in addition to the phase conjugation way of dispersion compensation. Dispersion compensation based on phase conjugation was also simulated and applied to OSSB millimeter-wave generator in order to transmit the generated signals through 100 km of fiber and data rate of 10 Gb/s without dispersion effect
