Abstract: This study explores the deployment of YOLOv8s for detecting anomalies in fiber optic cables mounted on poles, with a focus on climbing activities and environmental impediments. To address the lack of climbing-related annotations in current datasets, a custom dataset was generated, covering a variety of scenarios to enhance model adaptability. During training, various augmentation approaches were used, which greatly enhanced model performance and reduced overfitting. The proposed model was trained and tested over many epochs, with detection performance progressively improving: [email protected] increased from 78.9% at 20 epochs to 87.5% at 50 epochs and 97.3% at 100 epochs, after which further increases plateaued. In comparison, the trained YOLOv8s-modified model outperformed the other models on all key metrics. It achieved a mAP@50 of 97.3% and a mAP@50:95 of 71.5%, outperforming YOLOv8-original at 89.6% and 59.0%, respectively. Additionally, it achieved higher precision (96.9%) and recall (86.6%), demonstrating superior detection accuracy, dependability, and robustness in detecting complex anomalies. These improvements due to model backbone optimizations and the usage of a well-balanced, scenario-rich dataset. This study shows that YOLOv8s is a highly accurate and efficient method for detecting anomalies in fiber optic infrastructure, making it appropriate for real-time deployment in operational field environments.
