Graph Theory Web 0 - Image Index | Yenra Fiber Optic Close-Up: A close-up photograph of strands of optical fiber, each coated in thin layers of glass or plastic, with individual light sources at regular intervals along their lengths. The optical fibers are arranged diagonally across the frame and appear to be angled towards the right side. Several bright white lights are visible, emitting pink and blue light as they pass through the glass or plastic coating. Some areas have a purple hue due to reflection from the surrounding environment. A few strands of black material, possibly thin wires or more optical fibers, run along the length of the optical fiber bundles. The background is mostly black with blurry circles in various colors scattered throughout, giving a sense that the image was captured under low-light conditions and the camera has added an artificial glow to compensate.
