Abstract

This paper investigates the bit error rate (BER) performance of a radio-over-fibre system utilizing binary phase shift keying (BPSK) at radio frequency (RF) of 5 GHz. The RF signal is externally modulated using the Mach-Zehnder modulator (MZM). The results have been obtained for RoF link over 8, 30, 60 90 and 120 km distance to study the effect of dispersion and attenuation on signal and compare the results with on-off keying (OOK) modulation. The paper proves the chromatic dispersion has no effect on MZM whereas it has distinct effect on OOK modulation scheme
