This DMP serves as a comprehensive guide for managing the data generated during the MIR-FAST project. This project focuses on pioneering advancements in FSO communication technologies, specifically in the long-wave Infrared (LWIR) spectrum. The DMP outlines how we will handle, store, share, and preserve the data collected, ensuring it supports the project's objectives and is accessible for future research and development. The MIR-FAST project will generate and collect a variety of data crucial for advancing mid-infrared photonics technology. Specifically, the datasets will include Bit error Rate (BER) values, Spectrum Analysis Data, Eye Diagram Time Traces, etc. The data will also be stored in various formats, e.g., CSV. Data will be collected using sophisticated signal processing tools and optical measurement equipment. All data will be initially stored in raw format to ensure no initial data loss and then processed for analysis. In line with our commitment to advancing knowledge in the field of optical communications, the processed data will be made available to the research community. A dedicated data manager will oversee the implementation of this DMP, assisted by the project team. Responsibilities for data collection, processing, analysis, and sharing will be clearly defined within the project team to ensure adherence to the plan.
