Color Coding
The buffer or jacket on patchcords is often color-coded to indicate the type of fiber used.
Connector boot
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 or E2000) typically use a color-coded shell.
Standard color coding for jackets and boots (or connector shells) are shown below:
