TIA-598-D:2014

This standard defines the recommended identification scheme or
system for individual fibers, fiber units, and groups of fiber
units within a cable structure. The methods contained herein may be
used to identify and locate specific fibers for the purpose of
connection, termination, or testing within a communication system
or for the topography of long haul, feeder route, subscriber, or
distribution applications for both indoor and outside plant
use.

This standard also defines the optical fiber type identification
scheme for color coding or marking jackets for military cables or
indoor cables. Cables with colored jackets are typically used only
in intrabuilding applications and must be listed to a level of fire
resistance specific to their use. The jacket materials used can be
colored for identification purposes.

Conversely, most cables deployed outdoors must incorporate
additives in the jacket material to be able to withstand the
damaging effects of solar radiation over their designed operating
lifetime. Such products typically contain carbon black material to
provide the requisite level of protection, which precludes the use
of any jacket color other than black. Although color-compatible
materials designed to resist solar radiation are available for
outdoor use, and other means for color-coding black jackets are
possible (i.e., colored striping), the use of such materials and
methods are beyond the scope of this standard.
