A 12-color pigtail set gives each fiber in a splice tray its own color, so technicians can match pigtails to cable fibers without tracing. The fiber pigtail color order most often used follows TIA-598: blue, orange, green, brown, slate, white, red, black, yellow, violet, rose and aqua. Some operators and countries use a different sequence, so the color code has to be stated. This guide covers the color order, buffer and length choices, how the set fits the tray and ODF, and how to write it on a request.

| Position | Color | Position | Color |
|---|---|---|---|
| 1 | Blue | 7 | Red |
| 2 | Orange | 8 | Black |
| 3 | Green | 9 | Yellow |
| 4 | Brown | 10 | Violet |
| 5 | Slate | 11 | Rose |
| 6 | White | 12 | Aqua |
Fibers 13–24 often repeat the sequence with a stripe or dash marking. Regional codes, such as some European operator standards, use different orders; the FOA color code reference lists several. State the code that applies to your network.
A pigtail set should be ordered for a specific tray or panel position. Record the tray capacity (for example 12 or 24 splices), the adapter type and count on the panel, and the routing path. If one tray holds 12 splices, a 12-color set maps one-to-one; for 24-fiber trays, specify how the second group is marked.
In a typical ODF or closure, cable fibers arrive in loose tubes or ribbons that already follow a color code. When the pigtails in the tray follow the same code, the technician splices blue to blue, orange to orange and so on, without looking up a table or tracing each pigtail back to its adapter. The adapter position on the panel then matches the fiber number in the cable record. This reduces crossed fibers, makes acceptance testing easier because the port number equals the fiber number, and helps later repairs because any technician can read the tray. The benefit only holds if the color code of the pigtail set, the cable and the port numbering all agree, which is why the code belongs on the order.

FAQ
TIA-598: blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, aqua. Some regions use different sequences.
Each fiber in a tray gets a unique color, which speeds splicing and reduces errors.
0.9 mm tight buffer is common in splice trays; state another size if your trays need it.
Long enough to route from the adapter to the splice point with slack for re-splicing; it depends on the tray and panel.
