ANSI/TIA-598-D-1
Updated 2026-10-25
Data records
- ANSI/TIA-598-D-1 (2018) replaces clause 3.1 and the closing sentences of clauses 3.2 and 3.3 of ANSI/TIA-598-D (2014), renumbers the original color table as Table 1a, adds Table 1b for the 16-element base, and appends the new colors to the Munsell limits of Table 4.
- The foreword of ANSI/TIA-598-D-1 (2018) states that its content is to be incorporated into ANSI/TIA-598 at the next revision.
- ANSI/TIA-598-D-1 (2018) keeps the IEC abbreviation scheme of Annex C available for the original base but excludes it from the 16-element base, because that annex has no entries for the added colors.
- Under ANSI/TIA-598-D-1 (2018), positions from 13 upward name different colors in the 16-element base than in the original base, so a fiber number is unambiguous only when the base in use is known.
- ANSI/TIA-598-D-2 (2018) adds an informative Annex G bibliography citing ANSI/TIA-568.3, IEC 60793-2-10 and ISO/IEC 11801-1.
- ANSI/TIA-598-D-2 (2018) replaces the preferred indoor jacket color table, Table 3, of ANSI/TIA-598-D (2014), giving the laser-optimized and single-mode fiber classes separate rows, and adds the new jacket color to Table 4, Table 5 and Table B-1.
- ANSI/TIA-598-D-2 (2018) gives the OM5 jacket color its own Munsell limits and notes that they differ from those of the similarly named fiber color added by ANSI/TIA-598-D-1 (2018).
- A note to the jacket color table in ANSI/TIA-598-D-2 (2018) explains that single-mode cabled category also depends on cabled attenuation, so jacket color alone cannot distinguish OS1a from OS2.
- Clause 3.3 of ANSI/TIA-598-D (2014) treats a group as a collection of units, such as a tube holding ribbons or a ribbon assembled from sub-ribbons, and makes group identification optional.
- Clause 3.2 of ANSI/TIA-598-D (2014) treats a unit as a primary grouping of fibers, such as a buffer tube, a multi-fiber ribbon, a bundle held by thread or tape, or an ungrouped slot of a slotted core, and requires each multi-fiber unit to be uniquely identified.
- Clause 5.5 of ANSI/TIA-598-D (2014) specifies the north-sky daylight lighting condition under which colors are compared against Munsell references.
- ANSI/TIA-598-D (2014) bases its color limits on the ANSI/EIA standard colors for identification and coding and on Munsell notation as specified by ASTM D1535, and allows instrument methods that map to Munsell values to show compliance.
- Informative Annex C of ANSI/TIA-598-D (2014) gives an alternative scheme using IEC 60757 color abbreviations in the same position order, and notes that the IEC has no agreed positional method of its own.
- Clauses 3.5 and 3.6 of ANSI/TIA-598-D (2014) describe how binders identify units and groups at higher positions and define the longitudinal, spiral, ring and hachure tracer forms, with nominal coverage and spacing rules for each.
- Clause 3.1 of ANSI/TIA-598-D (2014) describes a printed block coding scheme in which combinations of solid blocks and bars represent the numeric position of a fiber.
- Clause 3.1 of ANSI/TIA-598-D (2014) allows fibers to be coded by coloring, by a printed legend, by printed block coding, or by another unique method agreed between maker and user.
- Clause 5 of ANSI/TIA-598-D (2014) sets Munsell hue, value and chroma limits for fiber, unit and group colors, allows deviations for materials such as PVC and halogen-free compounds that cannot meet them, and applies only color centroids to PVC jackets.
- Clause 6 of ANSI/TIA-598-D (2014) intends the colors to remain permanent for the design life of the cable and leaves the permanence test methods to the detail specification.
- Clause 3.1 of ANSI/TIA-598-D (2014) assigns a fixed sequence of base colors to fiber positions and extends it to higher positions by adding one tracer, then two tracers, then stripes, with each position also given a printed legend in numeric, abbreviated or combined form.
- ANSI/TIA-598-D (2014) is an identification document rather than a test method: it defines how fibers and units are told apart, and contains no instrument measurement to be made in the field.
- Clause 4.1 of ANSI/TIA-598-D (2014) applies the fiber, unit and group coding of clause 3 to indoor distribution cable unless otherwise specified, and clause 4.3 extends the indoor rules to sub-cables and cordage inside an indoor cable.
- Clause 4.2 of ANSI/TIA-598-D (2014) permits colored jackets or jacket printing to show fiber classification and size on indoor cable, and a cable holding only one fiber type and using its jacket color for that purpose follows the preferred jacket color table unless the jacket print identifies the classification.
- Clause 4.2.2 of ANSI/TIA-598-D (2014) requires an indoor cable carrying more than one fiber type to have the count of each type printed on its jacket unless otherwise specified, and clause 4.2.3 prefers the standard's category nomenclature for that printing.
- ANSI/TIA-598-D (2014) has clauses on scope, normative references, fiber, unit and group color coding, indoor cable color coding, color control and limits, and color permanence, with a normative Annex A of indoor cable definitions and informative Annexes B through F.
- Clause 3.4 of ANSI/TIA-598-D (2014) relaxes the scheme for simplex and duplex cable, permitting an uncolored fiber in simplex construction and a short list of discernible color pairings in duplex construction.
- Clause 3 of ANSI/TIA-598-D (2014) requires each fiber to be uniquely identifiable by color, unit, group or position, while noting that where the position of a fiber in a ribbon or slotted-core design already identifies it, the color scheme is preferred rather than required.
