In the standard TIA-598-C 12-color sequence, the brown fiber is Fiber #4.
The TIA-598-C standard assigns colors to individual fibers in a repeating 12-color sequence for identification within multi-fiber cables. The sequence is as follows: 1 – Blue, 2 – Orange, 3 – Green, 4 – Brown, 5 – Slate, 6 – White, 7 – Red, 8 – Black, 9 – Yellow, 10 – Violet, 11 – Rose, 12 – Aqua . Therefore, the brown fiber is the fourth fiber in each 12-fiber group.
For cables with more than 12 fibers, the 12-color sequence repeats for each subsequent group of 12 fibers. For example:
This systematic approach ensures that each fiber can be quickly identified during splicing, termination, or troubleshooting .
