A system (100) for the identification of the formation of a burning droplet (9) of a material of a fiber optic cable (3) during cable burn testing comprises a data processing device (11) for processing respective image data of a plurality of image samples of an image stream. The data processing device (11) is configured to execute at least a processing step of preprocessing each of the recorded image samples of the image stream to generate a respective preprocessed image sample for each of the recorded image samples such that areas of the recorded image samples disturbing the identification of burning droplets (9) are masked out in the respective preprocessed image sample, and a step of identifying a burning droplet (9) in each of the preprocessed image samples by evaluating a pixel color property of a pixel of each preprocessed image sample.
