Under the TIA/EIA-598-C standard, the universal 12-color sequence is: 1-Blue, 2-Orange, 3-Green, 4-Brown, 5-Slate (Gray), 6-White, 7-Red, 8-Black, 9-Yellow, 10-Violet, 11-Rose, and 12-Aqua. This sequence repeats for cables with more than 12 fibers. Global Consistency: Whether cables originate in North America, Europe, or Asia, the same 12‑color sequence applies—so any technician can interpret it correctly. * For cables >12 fibers: The sequence repeats with one or more black stripes (except black fibers, which receive yellow stripes) to. Prysmian uses the US industry standard repeating 12-color sequence. The long-length ADSS version allows pole-to-pole span lengths ranging from 400 feet under NESC heavy ice and wind loading conditions to 500. The color coding of fiber optic cables is typically determined based on the standards set by the International Telecommunication Union (ITU-T) or the Electronic Industries Alliance/Telecommunications Industry Association (EIA/TIA). Below are the common fiber optic color codes: The color sequence of.
