This Standard addendum was formulated as TIA Standards Proposal number TIA-PN-598-D-2 under the cognizance of TIA TR-42.12, Subcommittee on Optical Fibers and Cables. This addendum augments Sta
24、ndard ANSI/TIA-598-D. This addendum defines a new color for the jackets of indoor cables defined in ANSI/TIA-568.3-D that contain wideband laser-optimized 50/125 m multimode fiber specified by TIA-492AAAE. This cable is also defined in ISO/IEC 11801-1 as cabled optical fiber performance category OM5
25、 containing fiber specified in IEC 60793-2-10 as A1a.4. This new color will be incorporated into the next revision of TIA-598. Key words: OM5, WBMMF, wideband multimode fiber, wide band, wide-band, WDM, SWDM, lime, jacket color ANSI/TIA-598-D-2 iv This page left blank. ANSI/TIA-598-D-2 1 Optical Fib
26、er Cable Color Coding - Addendum 2, Jacket Color for OM5 Indoor Fiber Cables 1 Scope This addendum defines the recommended jacket color for indoor cables containing wide-band multimode fiber, WBMMF. These fibers are defined in TIA-492AAAE and in IEC 60793-2-10 for fiber model A1a.4. The performance
27、of cabled WBMMF is defined in ANSI/TIA-568.3. The cabled optical fiber performance category for WBMMF is designated as OM5 in ISO/IEC 11801-1. 2 Normative references The following standards contain provisions which, through references in this text, constitute provisions of this Standard. At the time
28、 of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

34、 of applications for these fibers, print nomenclature are to be agreed upon between manufacturer and end user.

Orange, for example, is different to facilitate ink marking. For color control, consideration should be given to using a E (deviation rang
38、e vector) value for deviations from the centroid, where E = Hue + Value + Chroma with the Hue, Value, and Chroma in Munsell notation (see text footnote #3). Using this system, E 6 indicates adequate control for most colors. 2) Munsell data for Lime are not available for weatherized PVC. ANSI/TIA-598
