Fiber Color ID

Built by a CFOT-certified fiber technician. Two-way fiber, tube and ribbon identification that works with no signal — handhole, splice trailer or bucket.

Fiber Color ID turns a fiber number into a color, and a color back into a fiber number. It is built for splicers, OSP technicians and engineers who need the right answer in a handhole, not a spreadsheet back at the office.

WORKS BOTH WAYS

• Enter a fiber number and get its tube or ribbon, its position in that unit, and both colors with the marking.
• Or pick the colors and markings you can actually see on the fiber and get the fiber number back.

BUILT FOR REAL CABLE

• Loose tube and ribbon construction.
• Standard counts from 12 up to 6,912 fibers.
• Custom cable counts and custom tube or ribbon sizes for non-standard builds.
• The 12-color sequence, with the repeat and marking logic that takes over above 144 fibers.
• Every fiber in the unit is drawn out with your fiber ringed, so you can count along the tube and check the app against what is in your hand.

WORKS WITH NO SIGNAL Every answer is arithmetic done on your device against a color table built into the app. No account, no sign-in, no network connection. It works in a vault, a manhole, a splice trailer, or anywhere else with no bars.

NO ADS, NO TRACKING No advertising and no analytics. The app does not collect information about you or about what you look up.

FREE AND PAID Free covers standard loose-tube cables up to 144 fibers. A single one-time purchase unlocks ribbon mode, custom tube and ribbon sizes, and counts above 144. It is a one-time purchase, not a subscription: nothing renews and there is nothing to cancel. If the store cannot be reached, an unlock already recorded on your device keeps working.

A NOTE ON CONVENTIONS Colors follow the standard 12-color sequence used across the industry. Some manufacturers use their own tube or marking conventions on particular products. Where your cable sheet disagrees with the app, trust the cable sheet, and please send us the cable structure so we can look at it.
