Fiber identification tool
A fiber identification tool has gotten unnecessarily complicated across most of the market — GPS-tracking platforms, full network-mapping suites, subscription dashboards that need a login before you can look anything up. Strip it back and the job only needs two or three things done well: tell you what fiber you're looking at, do it without a signal, and do it fast enough that you're not the bottleneck on a splice crew.

The category has drifted toward “platform” thinking — more dashboards, more account tiers, more features nobody asked for at the tray. A fiber tech standing over an open cable doesn't need a platform. They need an answer, in seconds, to one specific question: what color, what tube, what fiber number.
What identification actually means at the tray
Identifying fiber isn't a single lookup — it's two related but distinct questions techs run into constantly. Sometimes you know the fiber number and need the color: that's forward lookup. Sometimes you're staring at a tube color and fiber color in the tray and need to know which fiber number that actually is: that's reverse lookup, working backward from what's physically in front of you. A tool that only does one direction forces you to do the other direction's math yourself, which is exactly the kind of manual step a field tool should be removing, not leaving in.
AllFiber does both. Every lookup — 98,898 of them — is pre-computed and bundled offline, so there's no live calculation and no chance of a mental-math slip at 2am in a vault.
Coverage is the other half of “identification”
A tool that identifies fiber correctly for one manufacturer's cable and guesses for the rest isn't really an identification tool, it's a chart for one vendor. AllFiber covers 7 international color standards — TIA-598-C, IEC 60304, DIN VDE 0888, S12, FIN2012, IEC 60794-2, and Type E — across 199 cable configurations: 139 manufacturer-specific tube layouts spanning Corning, CommScope, Prysmian, AFL, OFS/Furukawa, and Sumitomo, plus 60 generic standards layouts for everything else. For the color-code side specifically, our 12 fiber reference and fiber optic color identification guide cover the standards themselves in more depth.
Identification has to survive the environment it's used in
None of this matters if the tool can't take the conditions techs actually work in. AllFiber runs fully offline off a bundled SQLite database — no signal required, whether that's a manhole, a vault, or basement OSP work. The dark theme UI is built for low-light field conditions, and tap targets are sized for gloved hands in cold or wet weather, not a phone screen designed for an office desk.
There's also an interactive SVG cable cross-section diagram with manufacturer-accurate tube positioning, so identification isn't just a text answer — you can visually confirm the physical layout matches what the tool told you, which matters when a cable doesn't look quite like the reference photo in your head.
Trying it before committing
A 24-hour free trial gives full access to everything, no account required. After that, a single one-time $4.99 purchase unlocks the whole app — no subscription, no tiered feature-gating, no recurring billing to track. For the deeper walkthrough of how the lookup workflow itself works day to day, see our guide to the fiber color code lookup app.
Frequently asked questions
What's the difference between forward and reverse fiber lookup?
Forward lookup answers “what color is fiber number X” — you know the number, you need the color. Reverse lookup does the opposite: you're looking at a tube color and fiber color in the field and need to know which fiber number that is. A complete identification tool needs both, since field techs run into each direction depending on the task.
Does a fiber identification tool need to work offline?
For field use, yes — manholes, vaults, and basement OSP environments routinely have zero signal, and a tool that requires connectivity to look up a fiber color is unusable exactly when it's needed most.
How many cable manufacturers does AllFiber's identification cover?
Six manufacturer-specific layouts (Corning, CommScope, Prysmian, AFL, OFS/Furukawa, Sumitomo) totaling 139 configurations, plus 60 generic standards layouts covering cable that doesn't match a specific manufacturer's proprietary tube arrangement — 199 configurations total.
Is there a subscription for a fiber identification app, or a one-time cost?
One-time cost only — $4.99 unlocks the full app after a 24-hour free trial, with no recurring billing or feature tiers.
