Abstract: The aim of this research project is to address the transmission of RF signals like UWB or Wireless LAN signals over cheaper Multimode fiber (MMF) links which are evolving along with the Gigabit / 10G Ethernet standards. The MMF link components were characterized as large signal equivalent circuit models and were implemented in ADS Spice simulator. The VCSEL model is a semiconductor rate equation model adopted for circuit simulation. The MMF model is a transfer function model whose Modal delays were calculated using WKB approximation. A pulsed UWB transmission over fiber is simulated and validated against the experimental results where the temporal signal qualities of the pulse were analyzed. Also WLAN IEEE 802.11a/11g system's EVM performances for ROF transmission predicted by the simulation were inline with experiments. Further it was used to predict the EVM performance of an IEEE 802.11a system in the presence of UWB signal over ROF.
