Which color code represents the largest gauge multimode fibers?

The color code for multimode fibers is essential in identifying their core size and intended use. In the case of multimode fibers, orange is designated for the largest gauge multimode fibers, which typically have a core diameter of 62.5 microns. This size is significant because it is widely used in local area networks (LANs), where the larger core allows for the transmission of multiple light modes, enhancing capacity and reducing signal loss over shorter distances.

Different color codes are established by standards such as TIA-598, which is recognized in the telecommunications industry, ensuring consistency and ease of identification for installers and technicians. While other colors in the code represent different types of fibers with varying core diameters, orange specifically aligns with the need for higher bandwidth and greater light-carrying capacity, making it suitable for many typical applications in fiber optic communications.
