Reference & Information

Fiber Wire Color Coding

This page describes wire color coding as defined by current military specifications. The color coding is used on the wiring insulation.
metallic insulation is listed on the Copper Wire Insulation Color Code page.
The National Electrical Code [NEC] requires their own coding system for premises wiring.
The National Fire Protection Association [NFPA]; specifies wire insulation colors for industrial machinery [machine tools].
These color codes may or may not apply to your specific application, because they apply to Drills, Motors, and so on.
The NFPA color scheme uses a solid color with another color strip for a number of applications.
NFPA color codes differ from NEC and Mil standard wire codes. For details, see: NFPA 79: Electrical Standard for Industrial Machinery.

The table above provides for optical fiber cable color coding [EIA 598-A].
EIA598 color codes the fibers once the cable are grouped into a bundle.

**Color coding of Premise Fiber Cable**
Fiber Type / Class	Diameter (µm)	Jacket Color
Multimode 1a	50/125	Orange
Multimode 1a	62.5/125	Slate
Multimode 1a	85/125	Blue
Multimode 1a	100/140	Green
Singlemode IVa	All	Yellow
Singlemode IVb	All	Red

The table above provides for optical fiber cable color coding when there is more then one types of cable in the jacket.
