Abstract
This paper presents a radio over fiber (RoF) system based on 24-tupled millimeter-wave generation using parallel Mach–Zehnder modulators (MZMs) and a semiconductor optical amplifier (SOA). By precisely configuring the parameters of two parallel MZMs, a frequency-octupled signal is generated, which is further converted into 24-tupled mm-wave using optical four-wave mixing (FWM) in SOA. A 5 GHz signal carrying 2.5 Gbps data is up-converted to 120 GHz signal, and BER of 4.9e−35 is obtained at transmission length of 15 km. Further, the performance of the presented scheme is analyzed by employing practical filters like Gaussian and Bessel filter and varying different parameters such as fiber length and SOA’ current. The results show that among the practical filters, the Gaussian filter provides better performance in terms of BER and required SOA’s current.
