Field guides
Practical write-ups for the people actually opening closures — color code sequences, strand identification on high-count cable, and the parts of the job where a laminated chart runs out.
Fiber Tech Pocket Reference: What It Needs to HoldThe 12 colors, the tube math, each cable's real build and its color standard — and why a 144F isn't always 12 tubes of 12.Fiber Optic Field Tools: The Five Jobs That MatterFiber optic field tools sorted by the five jobs they do: identify, clean, join, test, record. Plus an offline color code reference that works in a manhole.Best App for Fiber Techs: Offline Beats EverythingThe best app for fiber techs works with zero signal. The four checks that separate a real field app from a phone chart, and what the $4.99 one-time price covers.Fiber Optic Technician App: The Offline FundamentalsWhat a fiber optic technician app actually has to do in the field: offline lookup in both directions, manufacturer-specific tube layouts, and a 5-point test for any tool.Cable Identification App: What It Has to Do UndergroundWhat a cable identification app has to do underground: forward and reverse lookup, manufacturer-specific tube layouts, and fully offline operation with zero signal.Field Fiber Calculator: What Splice Techs Actually NeedWhy a field fiber calculator should look the answer up instead of computing it: forward and reverse lookup, manufacturer-specific tube layouts, and fully offline operation.Offline Fiber Reference: What Actually Works UndergroundWhat an offline fiber reference actually needs: data that ships with the app, lookup in both directions, and coverage across standards and manufacturers.Fiber Identification Tool: What the Job Actually RequiresForward and reverse lookup, offline access, and manufacturer coverage — what a real identification tool needs, not a platform.FTTH Installer App: What Actually Matters in the FieldWhat a good FTTH installer app actually needs to do: offline fiber ID, manufacturer coverage, and a UI that survives gloved hands.Splice Tech Tools: The Short List That Does the WorkThe eight tools that cover almost every splice, and what to check before blaming the splicer for a bad one.TIA-598 Color Code Chart: 12 Fiber Colors in OrderThe base twelve, why they repeat past fiber 12, and how tubes and fibers use the same list at once.Fiber Optic Color Identification: A Field Tech GuideHow the two-layer tube-and-fiber color system works, and how to read it on high-count cable.Fiber Color Code Lookup App: Offline Field GuideWhat forward and reverse lookup do, why offline matters underground, and what the app costs.
Reference charts
Looking for the raw sequences rather than a walkthrough? The color code charts cover 12, 24, 48, 96 and 144-fiber counts, including the TIA-598-D extension used on 16-fiber MPO breakouts.
