Main Article Content
Abstract
The future 5G wireless system will provide communication systems with a new advanced features to cover a large area with providing high bandwidth Millimeter wave (MM Wave) processing speed, in which case transmission technologies become more important and require large amounts of data, a large number of channels and lower cost. This paper reports the design of MM wave optical generation with 60 GHz based on RoF-WDM technique for long-distance optical fiber. The bloc scheme consists of 64 channels generated using Dual-Parallel Mach-Zehnder Modulator (DP-MZM) modulators for high data rate optical transmission. The performance was evaluated and analyzed in terms of various parameters such as optical fiber distance, input power and data rate, the simulation results are reported using Bit Error Rate (BER), Q-factor, Optical Signal-to-Noise Ratio (OSNR), and Eye Diagrams. The System efficiency provides an average BER of 4.0309e-10 with optical fiber link of 120 km and 10 Gbps data rate per channel, it also provides 18 Gbps per channel for 100 km of Standard Single Mode Fiber (SSMF). In this work, the integration of different techniques is viewed as a unique perspective of radio over fiber systems towards a wireless communication network.
