Pigtail color order

The standard color order for fiber optic pigtails follows the TIA-598-C sequence: Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose, Aqua. Standard 12-Fiber Color SequenceFor most singlemode and multimode pigtails, the 12-color sequence is used to identify individual fibers within a cable or pigtail pack: BlueOrangeGreenBrownSlate (Gray)WhiteRedBlackYellowVioletRose (Pink)Aqua This sequence is applied consistently across pigtails, buffer tubes, and connectors to ensure error-free identification during installation and splicing. Extending Beyond 12 FibersFor cables with more than 12 fibers, the color sequence repeats with stripes to maintain unique identification: Fibers 13–24: Repeat the 12 colors with one stripeFibers 25–36: Repeat the 12 colors with two stripesThis pattern continues for higher fiber counts, ensuring each fiber remains uniquely identifiable.

For example, Fiber #13 would be Blue with one stripe, Fiber #14 Orange with one stripe, and Fiber #25 Blue with two stripes.

Special Cases

Some high-density or European standards (e.g., DIN) use a 16-color sequence for MPO connectors: 13: Olive, 14: Magenta, 15: Tan, 16: Lime. Pigtails are typically supplied in sets of 6 or 12 colors, with both the fiber and buffer colored for easy identification. The standard applies to singlemode (OS2, G657A1) and multimode (OM1–OM5) fibers, and the color coding ensures global consistency across installations.

Practical Tips

Always verify the TIA-598-C compliance when purchasing pigtails to avoid misidentification. For high-count cables, use the tube and fiber system: the outer buffer tube has a color, and the fibers inside follow the 12-color sequence. Proper color coding reduces splicing errors, miswiring, and troubleshooting time in dense fiber networks.

By following this standardized color order, technicians can ensure accurate fiber identification and reliable network performance.
