Performance enhancement of 8 channel SCM–WDM based RoF link using different type of transmission fibers along with different type of channel spacing

Abstract

A system is represented that uses 20 nm of channel spacing and unequal channel spacing along with four different types of transmission fibers on subcarrier multiplexing–wavelength division multiplexing (SCM/WDM) based radio over fiber (RoF) link. These five different kinds of fibers have been analyzed offering different propagation parameters. In case of 20 nm of channel spacing the performance of the link is improved by 35.32% with the use of True wave fiber. In this paper, 8 channel SCM–WDM based RoF based model is simulated and analyzed with different type of optical fibers covering distance of 10 km. A comparison of Q-factor at different optical power and different optical lengths has been made. Q-factor, bit error rate and eye diagrams have been examined for assessing the performance of the model.
