Abstract

This work investigates the effect on the optical millimeter (mm)-wave long-haul RoF with pre-distortion systems and Fiber Bragg grating (FBG) techniques. Dual-Drive Mach-Zehnder Modulator (DDMZM) is used to generate the long-distance but inexpensive RoF mm-wave-based system by varying transmission rates of 1, 5, and 10 Gbps and power parameters of 0, 5, 10, and 15 dBm, respectively. Graphical analysis is done for Q-factor, Bit Error Rate (BER), and eye height with a 140 Km fiber link at a 10 Gbps bit rate. The results demonstrate that the system achieves excellent performance with a high Q-factor, low BER, and well-opened eye diagrams, confirming its feasibility for high-capacity and long-distance wireless access networks. Furthermore, the combination of pre-distortion and FBG techniques provides a scalable, low-cost, and energy-efficient solution, making the design highly suitable for next generation.
