TIA/EIA Standards Information
A number of Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA)
standards are applicable to wiring.
Following is a list of applicable standards:
• TIA/EIA Telecommunications Building Wiring Standards Collection
•
TIA/EIA-568A—Commercial Building Telecommunications Cabling Standard
• TIA/EIA-569A—Commercial Building Standard for Telecommunications Pathways and Spaces
•
TIA/EIA-570A—Residential Telecommunications Cabling Standard
• TIA/EIA-598—Optical Fiber Cable Color Coding
•
TIA/EIA-606—The Administration Standard for the Telecommunications Infrastructure of
Commercial Buildings
• TIA/EIA-607—Commercial Building Grounding and Bonding Requirements for
Telecommunications
•
TIA/EIA TSB 72—Centralized Optical Fiber Cabling Guidelines
• TIA/EIA TSB 75—Additional Horizontal Cabling Practices for Open Offices
•
TIA/EIA TSB 95—Additional Performance Guidelines for 4-Pair 100 OHM Category 5 Cabling
In addition, the following relevant standards are available from Global Engineering Documents:
•
FIBS PUB 175—Federal Building Standard for Telecommunication Pathways and Spaces
• FIBS PUB 176—Residential and Light Commercial Telecommunications Wiring Standard
Optical Fiber Color Codes
The most common color code for optical fiber is based on the ten colors that are used for plastic insulated
conductor copper cables. Two other colors have been added to bring the optical fiber color code to
twelve. These colors are now standardized under TIE/EIA-598—Optical Fiber Cable Color Coding.
The coloring specified in TIA/EIA–598 is used to identify individual optical fibers when the colors are
applied to the surface of the coated fiber or included directly in the fiber’s secondary coating. See
Table D-1 . Buffered fibers have colored plastic buffering jackets. The standard colors also may be used
to identify units (groups of fibers or loose tubes) or ribbons on a given cable. As well, units and ribbons
may be identified with printed markings.
