We know that different colors of the outer sheath of fiber optic jumpers represent different types of fiber optic jumpers. Do you often have this confusion and don’t know how to distinguish fiber optic jumpers based on the color of the outer sheath? This article will focus on the outer sheath colors of different fiber optic jumpers and how to distinguish fiber jumper types through the outer sheath of fiber optic jumpers.
TIA-598C is a color coding standard for fiber optic patch cords developed by the Telecommunications Industry Association of the United States. This standard defines the identification scheme for optical fibers and fiber optic patch cords. Below are the colors and corresponding fiber optic patch cord types for non-military and military applications.

In addition to the color of the optical fiber and sheath, you can also distinguish them by the color of the connectors and adapters of the optical fiber jumpers. The following table shows the information about the different colors of optical fiber connectors and adapters corresponding to different optical fiber jumpers.

In conclusion
This article details how to distinguish different fiber optic patch cords by the colors of their jackets, optical fibers, connectors and adapters. However, there are many types and colors of fiber optic patch cords on the market, and sometimes it is not possible to distinguish based on this information alone. At this time, you can check the model and specifications of the fiber jumper to help you better distinguish the fiber jumper.
