Wiring sequence for 24-core optical cable
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.
