In the domain of optical wireless communication and radio frequency heterogeneous networks (OWC/RF HetNet), the design of network topology is of paramount importance, posing a multifaceted challenge. This challenge arises due to the distinctive features of OWC and RF networks, as well as the differences in transmissions, both uplink and downlink, between optical and RF access points (APs). To address these issues, we introduce the Fuzzy Technique for Order Preference by Similarity to the Ideal Solution (Fuzzy TOPSIS) algorithm. It serves as a comprehensive method for simultaneously evaluating various attributes during the topology design process. We have developed a simulator for this algorithm, although it requires a substantial amount of time to execute due to its inherent complexity and the need to examine all potential network topologies. The resulting dataset contains valuable information collected after running the simulator, which is accessible to other researchers. They can utilize this dataset for comparisons and to enhance their own research outcomes. Furthermore, this dataset can be tailored to suit machine learning-based approaches in the topology design of OWC/RF HetNet. Within this dataset, we consider specific factors such as attainable data rates, node-to-AP distances, and cost-effectiveness as pivotal elements when formulating the topology for OWC/RF HetNet. #Quantities 'N_V': Number of optical APs 'N_R': Number of radio APs 'N_T': Number of nodes 'Counter': Count of reputation 'minC1_up', 'avgC1_up', 'maxC1_up': Residual or unoccupied data rates for Optical APs upload 'minC2_up', 'avgC2_up', 'maxC2_up': Residual or unoccupied data rates for radio APs upload 'minC4_up', 'avgC4_up', 'maxC4_up': Number of APs weren't employed by the topology in uplinks 'minC5_up', 'avgC5_up', 'maxC5_up': Price: very high or low for uplinks rate of optical to radio 'minC6_up', 'avgC6_up', 'maxC6_up': Distances between nodes and optical APs in uplink 'minC7_up', 'avgC7_up', 'maxC7_up': Distances between nodes and radio APs in uplink 'minC1_down', 'avgC1_down', 'maxC1_down': Residual or unoccupied data rates for Optical APs downlinks 'minC2_down', 'avgC2_down', 'maxC2_down': Residual or unoccupied data rates for radio APs downlinks 'minC4_down', 'avgC4_down', 'maxC4_down': Number of APs weren't employed by the topology in downlinks 'minC5_down', 'avgC5_down', 'maxC5_down': Price: very high or low for downlinks rate of optical to radio 'minC6_down', 'avgC6_down', 'maxC6_down': Distances between nodes and optical APs in downlinks 'minC7_down', 'avgC7_down', 'maxC7_down', Distances between nodes and radio APs in downlinks 'UpCount': Number of uplink topologies 'DownCount': Number of downlink topologies 'Total_Count': Total number of topologies 'ex_time': Excution time 'unused_vlc', 'unused_rf',
