Fiber Optic Color Codes by Fiber Type


Jacketed optical fibers are color coded according to fiber type. Color coding enables technicians to quickly determine whether a particular cable is multimode (e.g. orange or aqua) or singlemode (e.g. yellow or blue). The jacket imprint provides additional information, such as fiber size, fire code rating, and so forth. Be aware that the colors of some jacketed fiber varies from this standard.

Also note that bare fibers within buffer tubes are color coded differently than jacketed fiber. The chart below pertains only to jacketed fiber.
