Phase 1 · Fiber identification
Fiber Identification
The standard 12-position color sequence, buffer tube and ribbon identification, and a fiber-number lookup driven by documented cable constructions — never by an assumed universal chart.
TIA-598 sequence
Standard 12-fiber color code
The same 12-position sequence identifies fibers inside a unit and units inside a cable. Above 12 units the sequence repeats, and how a manufacturer marks the repeat (stripes, tracers, ring markers, subunit labels) differs by cable — always confirm against the construction record below.
Lookup tool
Find a fiber in a high-count cable
No documented construction is loaded for 1728F yet. Conduit only publishes constructions that are backed by a manufacturer document.
Pick a documented construction and enter a fiber number between 1 and the cable count.
