1. A surface defect detection device for detecting surface defects on at least one terminal surface of at least one optical fiber, said device comprising:
a digital microscope configured to capture an image of said at least one terminal surface; and
means for analyzing said image configured to detect surface defects present on said at least one terminal surface;
characterized in that said means for analyzing comprises a U-Net neural network having had its training phase carried out via an enhancer;
said enhancer is configured to create training images, for training said neural network, from reference images by only applying flips, rotations or luminosity, contrast, or shade variations to said reference images, wherein the created training images are configured to detect the surface defects.
