Design and Analyze the Impact of Photo Detectors with RZ and NRZ Encoding Scheme 40 Gbps Radio Over Fiber Link

For high capacity transmission such as broadband we require high speed. Therefore a combination of radio frequency with optical fiber is proposed known as radio over fiber. [1, 2] With the advent of this technique the system cost reduces because there is no need to design uplink and downlink. The application of radio over fiber includes cable television, network design, and uplink and downlink design and in satellite base station. In this paper, we design a Radio over fiber communication link with suppressed carrier amplitude modulated RF signal. After modulation signal is transmitted to the optical fiber of 50 km. For simulation Optisystem 13 is used. The results are compared and analyzed with the help of eye pattern generated by the BER analyzer. The input and output optical spectrum is studied with the help of optical analyzer whereas the RF signal is analyzed with the help of RF analyzer.
