Fiber Optic, Cat 5/5E, Cat 6 and Cat 7

TIA/EIA-568 is a set of telecommunications standards from the Telecommunications Industry Association (TIA), an offshoot of the Electronic Industries Alliance (EIA). The standards address commercial building cabling for telecommunications products and services.

As of 2014, the standard is at revision C, replacing the 2001 revision B, the 1995 revision A, and the initial issue of 1991, which are now obsolete.

Perhaps the best known features of TIA/EIA-568 are the pin/pair assignments for eight-conductor 100-ohm balanced twisted pair cabling. These assignments are named T568A and T568B.

An IEC standard ISO/IEC 11801 provides similar standards for network cables.

 

History

TIA/EIA-568 was developed through the efforts of more than 60 contributing organizations including manufacturers, end-users, and consultants. Work on the standard began with the EIA, to define standards for telecommunications cabling systems. EIA agreed to develop a set of standards, and formed the TR-42 committee, with nine subcommittees to perform the work. The work continues to be maintained by TR-42 within the TIA.

The first revision of the standard, TIA/EIA-568-A.1-1991 was released in 1991. The standard was updated to revision B in 1995. The demands placed upon commercial wiring systems increased dramatically over this period due to the adoption of personal computers and data communication networks and advances in those technologies. The development of high-performance twisted pair cabling and the popularization of fiber optic cables also drove significant change in the standards. These changes were first released in a revision C in 2009 which has subsequently received minor maintenance updates.

Goals

TIA/EIA-568 defines structured cabling system standards for commercial buildings, and between buildings in campus environments. The bulk of the standards define cabling types, distances, connectors, cable system architectures, cable termination standards and performance characteristics, cable installation requirements and methods of testing installed cable. The main standard, TIA/EIA-568-C.1 defines general requirements, while -568-C.2 focuses on components of balanced twisted-pair cable systems . TIA-568-C.3 addresses components of fiber optic cable systems, and -568-C.4, addressed coaxial cabling components.

The intent of these standards is to provide recommended practices for the design and installation of cabling systems that will support a wide variety of existing and future services. Developers hope the standards will provide a lifespan for commercial cabling systems in excess of ten years. This effort has been largely successful, as evidenced by the definition of category 5 cabling in 1991, a cabling standard that (mostly) satisfied cabling requirements for 1000BASE-T, released in 1999. Thus, the standardization process can reasonably be said to have provided at least a nine-year lifespan for premises cabling, and arguably a longer one.

All these documents accompany related standards that define commercial pathways and spaces (TIA-569-C-1, February 2013), residential cabling (ANSI/TIA-570-C, August 2012), administration standards (ANSI/TIA-606-B, June 2012), grounding and bonding (TIA-607-B-2, August 2013), and outside plant cabling (TIA-758-B, April 2012).

 

Cable categories

The standard defines categories of unshielded twisted pair cable systems, with different levels of performance in signal bandwidth, attenuation, and cross-talk. Generally increasing category numbers correspond with a cable system suitable for higher rates of data transmission. Category 3 cable was suitable for telephone circuits and data rates up to 16 million bits per second. Category 5 cable, with more restrictions on attenuation and cross talk, has a bandwidth of 100 MHz. The 1995 edition of the standard defined categories 3, 4, and 5. Categories 1 and 2 were excluded from the standard since these categories were only used for voice circuits, not for data.
