What color typically indicates laser-optimized 50/125 OM3 or OM4 fiber in premises cable jackets?

The color typically indicating laser-optimized 50/125 OM3 or OM4 fiber in premises cable jackets is aqua. This color coding is significant as it helps technicians and installers quickly identify the type of fiber cable during installation or maintenance tasks. OM3 and OM4 fibers are designed specifically for high bandwidth applications, and the aqua color is standardized in the industry to prevent any confusion with other types of fibers that may have different performance characteristics.

While other colors like yellow and orange are used for different types of fiber, such as single-mode (yellow for 9/125) and multimode fibers (orange for OM1 and OM2), they serve distinct purposes. Purple is less commonly used and does not denote either OM3 or OM4 fibers. Recognizing these color codes is crucial for ensuring that the right types of fibers are used in specific applications, particularly in environments where performance and compatibility are essential.
