The tubes themselves are also color-coded for identification. Tube Color Coding for Loose-Tube Cables (12-Tube Standard): Blue Orange Green Brown Slate White Red Black Yellow Violet Rose AquaWolonFiber's 12-Color Fiber Optic Pigtail Packs are manufactured strictly to the TIA-598-C standard with vibrant, easy-to-identify colors. Perfect for fast, error-free termination in your ODF or splice closures. Available in OS2/OM3/OM4 at factory-direct wholesale pricing. Hexatronic offers cables with color code systems according to all interna ional and national standards and for all types of fiber opti such as a tube, ribbon, yarn wrapped bundle or other types of bundle. You rely on these color systems to ensure correct fiber routing, splicing accuracy, tube identification, polarity. The TIA/EIA-598-C standard is the most widely followed guideline for color coding in optical fiber cables, both for loose-tube and ribbon fiber cables. TIA/EIA-598-C Standard Color Code for Optical. Fiber optic color codes follow a 12-color sequence defined by TIA-598: blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, aqua. The same twelve colors identify individual fibers, and they repeat to identify buffer tubes — so in the common 12-fibers-per-tube build, 12 tubes. The standard defines a 12-color sequence that cycles through tubes and repeats for fibers within each tube, allowing unique identification of every fiber in cables up to 288 fibers and beyond. Standard cable construction groups 12 fibers into each buffer tube.
