The buffer or jacket on patch cords is often color-coded to indicate the type of fiber used. The strain relief boot that protects the fiber from bending at a connector is color-coded to indicate the type of connection. Connectors with a plastic shell (such as SC connectors) typically use a color-coded shell. Standard color codings for jackets (or buffers) and boots (or connector shells) are shown below: Remark: It is also possible that a small part of a connector is additionally color-coded, e.g., the lever o
