Structured Cabling Systems - LAN Wiring - page 64

It is widely agreed that the flexibility and utility of the standard TIA-568-C sys-
tem offers the best alternative for new installations.
The standard can be used in lieu of the proprietary cabling systems, with little
difference in performance. It can easily support a wide variety of LAN topologies,
and offers growth to 100 Mbps and beyond.
TIA-568-C Structured Cabling
The TIA-568-C Commercial Building Telecommunications Wiring Standard
describes a generic cabling system that can support many types of LANs, as well as
many other telecommunications applications.
In this section, we will cover the hardware and wiring issues presented by the
standard. And, of course, the details of many of the wiring components are covered
elsewhere in this topic. We will rather loosely group the requirements of TIA/EIA-
568-C and its predecessor documents, EIA/TIA 568, TIA/EIA-568-B, TSB-36, TSB-
40, TSB-53, TSB-67, TSB-72, and TSB-95 under the label “TIA-568-C.” The
installed link testing requirements of TSB 67 (which you may see in older docu-
ments) and many measurement enhancements are incorporated into TIA/EIA-568-
C, and provide testing guidelines for this cabling system.
TIA/EIA-568-C Highlights
The latest enhancement to the famous TIA-568 standard is the “C” revision.
The standard is split into four parts, designated “C.0,” “C.1,” “C.2,” and “C.3” that
cover generic cabling requirements, commercial building cabling design, 100-ohm
twisted-pair cabling components, and optical-fiber cabling components, respectively.
Here are the formal standard names and their predecessor documents.
ANSI/TIA/EIA-568-C 2006 Commercial Building Telecommunications
Cabling Standard (formerly ANSI/TIA/EIA-568-B 2000)
This new standard replaces ANSI/TIA/EIA-568-B; incorporates and refines the technical
content of TSB-67, -72, -75, -125, -140, -155, and -162; ANSI/TIA/EIA-568-B.1, includ-
ing Addenda AD-1 through AD-7; ANSI/TIA/EIA-568-B.2, including Addenda AD-1
through AD-11; and ANSI/TIA/EIA-568-B.3, including Addenda AD-1.
