Power Fading Effects in Millimeter-Wave Radio Over Fiber (RoF) Link
2015The use of fiber-based wireless system has offered a reliable and cost effective communication system. Such system greatly provides superior possible bandwidths for both fiber and free-space applications. For that reason, radio over fiber (RoF) technology is the best preference to deal with the improved capacity and mobility mainly at higher frequency.

Radio-over-fiber (RoF) links based on reflective electro-absorption modulator (REAM)
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012There are two types of optical signal modulation in optical communication systems: the direct modulation of the laser diode (LD) radiation and the indirect modulation by using an external modulator. External electro-absorption modulators (EAMs) attracted a great attention in high-speed applications due to low cost, possibility of integration with LDs ...
