Abstract: Radio over fibre (RoF) is a revolutionary technology, which integrates radio and optical networks with a substantial bandwidth for wireless communication systems with minimum distortion and low cost. This paper investigates the performance of a radio over fibre system for high speed, moderate data of 10 Gbps encoded by RZ and NRZ code. The Mach-Zehnder modulator (MZM) is used to modulate the encoded data using 60 GHz radio frequency (RF). The results are obtained for the RoF system for the optical fibre of various lengths of 30, 45, 60 and 70 km. The performance of RZ and NRZ encoding is discussed using BER, Q factor, eye diagram and output power. It is observed that NRZ performs better than RZ for long haul communication.
