Employing broadband light source on FTTx/RoF transmission system

This paper presents a spread radio-on-fiber wavelength-division multiplexed (Radio-over-WDM) scheme of transport system. In this paper, user-extension effect is investigated on using only one broadband light source in the local oscillator (LO). Not only effectively reduces the complexity of system, but also reduces the cost of system construction. After more than 40-120 kilometer transmission, it can be expected a good system performance on the bit error rate (BER), and a good eye diagram.
