Four signals 1550 nm, 1552 nm, 1553 nm, 1555 nm is shown in optical spectrum analyzer at the output of MUX in the central station as in fig.7.2. And video signal is shown in fig.7.1. The whole Radio over Fiber system consists of wavelength division multiplexing and optical add-drop multiplexing techniques. This is simulated using Opt system 10. WDM technique is used to transmit four different signals through a single fiber for long distance. OADM technique enabled us to transmit both down-link and uplink data via the same single-mode fiber. EDFA is used to amplify the signals after every 40 km of the transmission link. . At the receiver station some noise signals are presented with required signals but desired signals are detected easily due to higher amplitude of that signals. The proposed system is suitable for high bit rate and long-haul microwave optical links.
