Which feature is typical of the outer jackets on most communications cables?

• A. Color-coded jackets
• B. Metallic jackets
• C. Textured jackets
• D. Transparent jackets

Answer: (A)

Color-coded jackets provide a quick way to identify a cable’s function and type at a glance, which is essential in dense installations or when tracing cables in a bundle. The jacket color helps distinguish copper data cables from fiber, indoor versus outdoor use, or different category ratings, so technicians can install and troubleshoot efficiently without needing to inspect every cable in detail. While outer jackets can be made from various materials and may include armor or special textures in some cases, the common practice for most communications cables is to use color coding to aid identification.
