TABLE 5.3. Standard Optical Fiber Jacket and Loose-Tube Color Identifications

Fiber number Color Fiber number Color
1 Blue 13 Blue/black tracer
2 Orange 14 Orange/yellow tracer
3 Green 15 Green/black tracer
4 Brown 16 Brown/black tracer
5 Slate (gray) 17 Slate/black tracer
6 White 18 White/black tracer
7 Red 19 Red/black tracer
8 Black 20 Black/yellow tracer
9 Yellow 21 Yellow/black tracer
10 Violet 22 Violet/black tracer
11 Rose (pink) 23 Rose/black tracer
12 Aqua 24 Aqua/black tracer

through 24 repeat the same fundamental color code used for strands 1 through
12, with the addition of a black or yellow dashed or solid tracer line, as noted in
Table 5.3. For cables having more than one loose tube, the tubes also are color-
coded in the same manner as the fibers; that is, tube 1 is blue, tube 2 is orange,
and so on.
Ribbon cables follow the same color-coding scheme. Thus, one of the outside
fibers would have a blue jacket, the next fiber would be orange, and so on until
the other outer edge is reached where, for a 12-fiber ribbon, the fiber would be
aqua (light blue).
