AllFiber Color Code
The fastest TIA-598 fiber color code lookup app for field technicians. Open a 144-fiber cable in a hand-hole and know exactly which tube holds fiber 47 — in two taps, fully offline. Seven international standards, 162 cable configurations, 49,782 pre-computed lookups. $4.99 one-time — no subscriptions, no ads.
What it does
Three core lookups, every one of them designed for a vault floor where you can't take off your gloves and can't get a signal:
- Forward lookup — enter a fiber number, get the tube color and fiber color. Fiber 47 in a 144F? Brown tube, Rose fiber.
- Reverse lookup — see a tube and fiber color in the cable, get the fiber number. Filter excludes colors not used by your active standard so you can't pick an invalid combination.
- Interactive diagram — manufacturer-accurate SVG cross-section of every supported cable. Tap any tube or fiber. Pinch to zoom on cables > 24 tubes.
The TIA-598-C 12-color base sequence
TIA-598-C defines a 12-color order used for both loose-tube IDs and individual fiber IDs inside each tube. Memorize it once and you can identify any fiber in any standard-sequence cable:
- 1. Blue
- 2. Orange
- 3. Green
- 4. Brown
- 5. Slate
- 6. White
- 7. Red
- 8. Black
- 9. Yellow
- 10. Violet
- 11. Rose
- 12. Aqua
The sequence is always the same whether you're identifying tubes (for larger counts) or individual fibers inside a tube. Tube colors repeat the fiber colors in order: tube 1 is Blue, tube 2 is Orange, tube 3 is Green, etc. Past tube 12, tubes repeat with a tracer stripe to disambiguate (tube 13 = Blue with Black tracer, etc.).
How tube + fiber color combine
In a multi-tube cable, each fiber's position is read as (tube color, fiber-within-tube color). To locate any fiber number by hand:
- Divide (fiber number − 1) by fibers-per-tube to get the tube index.
- The remainder + 1 is the fiber index within the tube.
- Look both up in the sequence above.
Example: fiber 47 in a 144F cable (12 fibers per tube). (47 − 1) ÷ 12 = 3 remainder 10. Tube 4 = Brown. Fiber-within-tube 11 = Rose. So fiber 47 = Brown tube, Rose fiber. The app does this for you instantly across every standard and every manufacturer layout.

TIA-598-D extension (for 16-fiber MPO connectors)
MPO/MTP breakouts with 16 fibers use TIA-598-D, which adds four more colors beyond the base 12. You'll see these in data-center trunks and 400G/800G breakout cables:
- 13. Olive
- 14. Magenta
- 15. Tan
- 16. Lime
Supported standards
Outside North America you'll encounter IEC 60304 (global IEC), DIN VDE 0888 (Germany), S12 (Japan/NEC legacy), FIN2012 (Finland), IEC 60794-2, and Type E (Ericsson/Nortel legacy). Most share the first six TIA-598-C colors but diverge on positions 7–12 — which is where splice errors happen when crews cross standards. AllFiber Color Code includes all seven so you can switch standards from the settings screen when you're working on a non-US build.
Supported manufacturers
The app ships with 60 generic configurations that cover any TIA-598-compliant cable, plus 102 manufacturer-specific layouts across these five vendors:
- Corning — multiple product lines with accurate tube ring layouts
- CommScope — TeraSPEED, LightScope, and other lines
- Prysmian — including Sirocco and FlexTube
- AFL — Spider, LightLink, and central tube configurations
- OFS / Furukawa — AccuRibbon, Sumotube, and others
Who it's for
Fiber optic field technicians who do splicing, terminations, OTDR testing, or fault location. Specifically:
- Outside Plant (OSP) techs working in vaults, manholes, and pedestals
- FTTH installers running drops and verifying tube counts
- Backbone crews on 144F/288F/432F long-haul builds
- Data center fiber techs handling MPO/MTP breakouts
- Fiber inspection and OTDR test crews

Frequently asked questions
What is the TIA-598-C fiber color code?
TIA-598-C is the North American standard 12-color sequence for fiber optic cables: Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose, Aqua. The same sequence is used for both buffer tubes and individual fibers within each tube.
Does the app work offline?
Yes. All 49,782 fiber lookups and 162 cable configurations are pre-computed and bundled with the app at install time. It works in vaults, manholes, and aerial lifts where cellular signal is unreliable or unavailable.
Which international standards are supported?
Seven standards: TIA-598-C (North America), TIA-598-D (extended for 16-fiber MPO), IEC 60304 (global IEC), DIN VDE 0888 (Germany), S12 (Japan/NEC legacy), FIN2012 (Finland), IEC 60794-2, and Type E (Ericsson/Nortel legacy).
Can I use it on tablets?
Yes. The iOS build supports iPad and the Android build supports Android tablets. The cable diagram benefits from the larger screen, especially on cables larger than 144F.
