Radio Over Fiber Millimeter Wave Generation for 5G Communication Applications

Radio Frequency (RF) waves at 2.5 and 5 GHz have been used to generate millimeter (mm) wave frequencies at 90 and 180 GHz using two cascaded dual parallel Mach–Zehnder modulators (DP‐MZM). In Radio over Fiber (RoF), 36‐tupling is employed to maximize the signal quality by modifying the bit rate up to 20 Gbps over a 50 km single‐mode fiber distance. The characteristics research is graphically analyzed in terms of fiber length, bit error rate, quality factor, Optical Sideband Suppressing Ratio (OSSR), and Radio Frequency Spurious Sideband Suppressing Ratio (RFSSR) at 10 and 20 Gbps with a minimal Bit Error Rate (BER) of 10 −9 . The performance of the generated millimeter wave was evaluated at the receiver. Furthermore, the consistency of the theoretical and simulation results proved the usefulness of the system.
