A 40 Gbps Ro-FSO transmission system for 5 G applications

Never-ending demand for higher data rate has led the research to focus on new kind of networks (5G) which can support increasing number of users. To handle such traffic, integration use of millimetre (mm) wave is proposed with free space optical networks. This work focuses on transportation of 40 GHz radio signal over free space optical link. Four independent channels are used with a data rate of 10 Gbps and 40 GHz radio signal are transported over 400 m free space link by employing On-Off Keying (OOK). Analysis of the received output signal is performed using BER and eye diagrams. Furthermore, comparison of Non- Return to Zero (NRZ) and Return to Zero (RZ) modulation schemes are also investigated.
