- Abstract
The research community and telecommunications companies have developed new methods for bandwidth optimization. The high transport capacity of optic fiber links and the high flexibility of wireless networks have done the Radio over Fiber (RoF) technology be considered as a promising alternative for the solution of the increasing bandwidth and network access requirements. The performance of the RoF systems has been widely analyzed; however, it is also important to understand the behavior of the Symbol Error Rate (SER) when the distances and the modulation schemes are modified. The behavior of a RoF system with OFDM (Orthogonal Frequency Division Multiplexing) carriers at 900 MHz is evaluated considering the variation of the distance in the optic fiber inks and the multilevel modulation (in phase and in quadrature) in the radio interfaces. It is possible to state that the 16 QAM modulation schema offers the best balance between spectral efficiency, performance in terms of the symbol error rate (SER) and distance. With this modulation schema it is possible to achieve distances of 60 Km with SER values of 10-3.
