Since the earliest days of fiber optics, multimode cables have typically been color‑coded orange, black, or gray, while single‑mode cables are marked in yellow. For example, cable jacket color typically defines the fiber type, and can differ based on mode and performance level. These colors are typically chosen by industry standards bodies. However, there are some non-standardized colors and inconsistencies that you should be aware of. However, with the introduction of metallic connectors like FC and ST—whose bodies are difficult to color‑code—colored strain relief boots. Multimode fiber (MMF) is a kind of optical fiber mostly used in communication over short distances, for example, inside a building or for the campus.
