Order of Red Green White and Yellow Optical Cables

In a standard TIA/EIA-598-C fiber optic cable, the sequence of the four fibers is Green, White, Red, Yellow.Standard 12-Fiber Color SequenceThe TIA/EIA-598-C standard defines a 12-color sequence for individual fibers in a cable, which is widely used for both loose-tube and ribbon fiber cables. The full sequence is: Blue, Orange, Green, Brown, Slate (Gray), White, Red, Black, Yellow, Violet, Rose (Pink), Aqua (Light Blue) .From this sequence, the specific order of the four fibers you asked about is:Green (3rd fiber)White (6th fiber)Red (7th fiber)Yellow (9th fiber)This order is consistent whether the fibers are in a single tube or part of a multi-tube cable. For cables with more than 12 fibers, the sequence repeats in groups of 12, sometimes with additional markings to distinguish repeated sets .Practical ImplicationsInstallation and Splicing: Knowing the correct order ensures proper fiber identification and prevents miswiring.High-Density Cables: In cables exceeding 12 fibers, the same 12-color sequence is applied to each bundle or tube, maintaining consistency.Maintenance: Technicians can quickly locate and trace fibers using the standardized color sequence, reducing errors and downtime.By following this standard, fiber optic networks maintain global consistency, allowing technicians to work across different manufacturers and regions without confusion .
