Abstract: There is continuous growth in demand of internet traffic among end users for various applications. This results in overcrowding and interference of data at microwave region. Numerous research is being carried out in the field of broadband technology to achieve high performance and high data rate, as with the increase in demand of application and various high bandwidth application at the end user terminal is a stress over data rate. Increased interference leads to deterioration in network performance. A promising solution to this problem, is integration of network evolved from wireless and optical fiber network at very high frequency in millimeter (mm) wave range such as 60GHz – 70GHz to cope up the need of bandwidth which result in increased mobility and provide large instantaneous bandwidth. There is a need of shifting frequency of operation to high frequency region in mm. As the propagation characteristics such as reflection, refraction and scattering are less at high frequency, high frequency of operation at mm wave can be proved to be a promising solution to provide high data rate with enhanced performance. In this project four technologies for increasing the bandwidth of network with decrease in cost of system were reviewed .Including photonic mm wave generation using based on external intensity modulation and non-linear effects in fiber using principal of frequency quadrupling and sextupling. From all these four different proposed techniques we conclude that dual-parallel MZM is the most cost effective and promising solution for frequency quadrupling and copes with the increasing frequency demand in the market.
