This easy-to-follow reference guide is designed to assist you in
installing, terminating and testing category unshielded twisted pair
(UTP) cables to maximize their performance and ensure they meet or
exceed ANSI/TIA/EIA 568 B standards.
Overview of Cabling Standards
ANSI/TIA/EIA 568 B
ANSI/TIA/EIA 568 B ('568 B) replaced ANSI/TIA/EIA 568 A as the
“Commercial Building Telecommunications Cabling Standard” in May
2001. All addenda of 568 A and all TSBs (67, 72, 75 and 95) have
been incorporated into the new standard.
The 568 B document is broken into three sections:
B.1 - General Requirements
B.2 - Balanced Twisted Pair Cabling Components
B.3 - Optical Fiber Cabling Components Standards
For clarity and consistency, '568 B based terminology is used in the
following overview.
Purpose
• To specify a generic voice and data telecommunications cabling system
that will support a multi-product, multi-vendor environment.
• To provide direction for the design of telecommunications
equipment and cabling products intended to serve
commercial enterprises.
• To enable the planning and installation of a structured cabling
system for commercial buildings that is capable of supporting the
diverse telecommunications needs of building occupants.
• To establish performance and technical criteria for various types
of cable and connecting hardware, and cabling system design and
installation.

Structure
Work Area (WA)
Some points specified for the horizontal cabling subsystem include:
• Recognized Horizontal Cables:
• 4-pair 100 unshielded
twisted pair (UTP), screened
twisted pair (ScTP) or Mosaic
Twisted Pair (MTP)
• 2-fiber (duplex) 62.5/125µm
or 50/125µm
• Multi-pair and multi-unit cables are allowed, provided that they
satisfy the hybrid and bundled cable requirements of
TIA/EIA 568 B.2.
• Grounding must conform to applicable building codes, as well as
ANSI/TIA/EIA 607.
• A minimum of two telecommunications outlets are required for
each individual work area per TIA/EIA 568 B.1.
First outlet: 100 Category 3 twisted pair
(Category 5e is recommended).
Second outlet: 100 Category 5e
twisted pair (Category 6 is recommended)
or two-fiber multi-mode optical fiber, either
62.5/125µm or 50/125µm.
• One transition point (TP) is allowed between different forms of the
same cable type (e.g., where undercarpet cable connects to round cable).
• 50 coax and 150 STP-A cabling are not recommended for new
installations.
• Additional outlets may be provided. These outlets are in addition to
and may not replace the minimum requirements of the standard.
• Bridged taps and splices are not allowed for copper-based
horizontal cabling (splices are allowed for fiber).
• Application-specific components shall not be installed as part of
the horizontal cabling. When needed, they must be placed external
to the telecommunications outlet or horizontal cross-connect (e.g.,
splitters, baluns).
• The proximity of horizontal cabling to sources of electromagnetic
interference (EMI) shall be taken into account.

Horizontal Cabling System
Structure
Star Topology
Horizontal cabling shall be configured in a star topology, with each
work area outlet connected to a horizontal cross-connect (HC) in a
telecommunications room (TR).
Home Run Cabling

Work Area
The telecommunications outlet serves as the work area interface
to the cabling system.
Adapters and applicationspecific devices (such as
baluns) shall be external to the
telecommunications outlet.
Some specifications related to work area cabling:
• Equipment cords are assumed to have the same performance as
patch cords of the same type and category.
• When used, adapters are assumed to be compatible with the
transmission capabilities of the equipment to which they connect.
• Horizontal cable lengths are specified with the assumption that a
maximum cable length of 3m (10 ft.) is used for equipment cords in
the work area.
Note: For establishing maximum horizontal channel distances, a
combined maximum length of 10m (33 ft.) is allowed for patch
cables (or jumpers) and equipment cables in the work area and the
telecommunications room.
6
Horizontal Distances of Copper
Links (Open Office)
Copper work area cables connected to a MuTOA (Multi-user
Telecommunications Outlet Assembly) shall meet the requirements of
'568 B.1. The maximum length of copper work area cables shall be
determined according to:
C=(102-H)/1.2
W=C-5(<20m)
Where:
C is the combined length of the work area cable,
equipment cable and patch cord (m).
W is the length of the work area cable (m).
H is the length of the horizontal cable (m).
The above equations assume that there is a total of 5m (16 ft.) of
patch and equipment cables in the telecommunications room.
Table 1 shows the application of these formulas. The length of work
area cables shall not exceed 20m (66 ft.). The MuTOA shall be marked
with the maximum allowable work area cable length.

TIA/EIA 568 B.2
The transmission performance of a cabling system depends upon the
characteristics of the horizontal cable, connecting hardware, patch
cords, equipment cords, work area cords, cross-connect wiring,
the total number of connections, and the care with which they
are installed and maintained. The development of high-speed
applications requires that cabling systems be characterized by
transmission parameters such as insertion loss, PSNEXT loss, return
loss, and PSELFEXT. Category 6A cables include the additional
transmission parameters PSANEXT and PSAACRF. System designers
use these performance criteria to develop applications that utilize
all four pairs in a cabling system for simultaneous bi-directional
transmission. This standard provides minimum cabling component
performance criteria as well as procedures for component and cabling
performance validation. This standard also specifies field test
instruments and applicable reference measurement procedures for all
transmission parameters.
This standard specifies minimum requirements for balanced twistedpair telecommunications cabling components that are used up to
and including the telecommunications outlet/connector and between
buildings in a campus environment. This standard specifies the
minimum performance requirements for recognized balanced twistedpair cabling components as described in ANSI/TIA/EIA 568 B.1
(i.e., cable, connectors, connecting hardware, patch cords, equipment
cords, work area cords and jumpers) and for the field test equipment
used to verify the performance of these components as installed.
TIA/EIA 568 B.3
Optical Fiber Cabling Components
This standard contains the performance specifications for the
optical fiber cables recognized in premises cabling standards. Cable
transmission performance for the outside plant telecommunications
cable shall comply with ANSI/ICEA S 87-640. Inside plant optical fiber
telecommunications cable shall comply with ANSI/ICEA S 83-596. Each
cabled fiber shall meet the graded performance specifications of the
table to the right.
12
TIA/EIA 568 B.3
The optical fiber cable construction shall consist of 50/125mm or
62.5/125mm Multimode optical fibers or Singlemode optical fibers,
or a combination of these media. Individual fibers or groups of fibers
shall be identifiable in accordance with ANSI/TIA/EIA 598 A. The cable
shall be listed and marked as required under the applicable electrical
code and local building code requirements.
Bend Radius:
Inside plant: 2- and 4-fiber cables intended for horizontal or
centralized cabling shall support a bend radius of 1 inch under
no-load conditions. 2- and 4-fiber cables intended to be pulled
through horizontal pathways during installation shall support a bend
radius of two inches under a pull load of 222N (50 lbf). All other
inside plant cables shall support a bend radius of 10 times the cable’s
outside diameter when not subject to tensile load, and 15 times the
cable’s outside diameter when subject to tensile loading up to the
cable’s rated limit.
Outside plant: Optical fiber cables shall be of a water-block
construction and meet the requirements for compound flow and water
penetration. Outdoor cable shall have a minimum pull strength of
2670N (600 lbf). Outside plant cables shall support a bend radius of
10 times the cable’s outside diameter when not subject to tensile load,
and 20 times the cable’s outside diameter when subject to tensile
loading up to the cable’s rated limit.

Straight-Through or Reversed
Modular cords are used for two basic applications. One application
uses them for patching between modular patch panels. When used in
this manner, modular cords should always be wired “straight-through”
(pin 1 to pin 1, pin 2 to pin 2, pin 3 to pin 3, etc.). The second major
application uses modular cords to connect the workstation equipment
(PC, phone, FAX, etc.) to the modular outlet. These modular cords may
either be wired “straight-through” or “reversed” (pin 1 to pin 6, pin 2
to pin 5, pin 3 to pin 4, etc.), depending on the system manufacturer’s
specifications. This “reversed” wiring is typically used for voice
systems. The following is a guide to determine what type of modular
cord you have.
How to Read a Modular Cord
Align the plugs side-by-side with the contacts facing you and compare
the wire colors from left to right. If the colors appear in the same
order on both plugs, the cord is wired “straight-through.” If the colors
appear reversed on the second plug (from right to left), the cord is
wired “reversed.” To do a cross-over, put 568 A on one end and 568 B

Common Outlet Configurations
Two wiring schemes have been adopted by the '568 B and '11801
Standards. They are nearly identical, except that pairs two and three
are reversed. T568 A is the preferred scheme because it is compatible
with 1- or 2-pair USOC systems. Either configuration can be used
for Integrated Services Digital Network (ISDN) and high speed data
applications. Transmission Categories 3, 5e and 6 are only applicable
to this type of pair grouping.

*CAUTION
Quad wire is no longer acceptable for installation in multi-line
environments. If encountered during a retrofit, quad wire should be
replaced with 100 UTP if possible. Connecting new quad to installed
quad will only amplify existing problems and limitations associated
with quad wire. Leaving existing quad in place and connecting
100 UTP to it may also be ineffective, as the quad wire may negate
the desired effect of the UTP.

Recommended Cabling
Practices
Do:
• Do terminate each horizontal cable on a dedicated
telecommunications outlet.
• Do locate the main cross-connect near the center of the building
to limit cable distances.
• Do maintain the twist of horizontal and backbone cable pairs up
to the point of termination.
• Do tie and dress horizontal cables neatly.
• To avoid stretching, pulling tension should not exceed 110N
(25 lbf) for 4-pair cables.
• Installed bend radii shall not exceed:
- 4 times the cable diameter for horizontal UTP cables.
- 8 times the cable diameter for horizontal screened & MTP cables.
- 8 times the cable diameter for backbone screened & MTP cables.
- 10 times the cable diameter for multi-pair backbone UTP cables.
• Horizontal cables should be used with connecting hardware and patch
cords (or jumpers) of the same performance category or higher.
• Avoid cable stress, as caused by:
- cable twist during pulling or installation
- tension in suspended cable runs
- tightly cinched cable ties or staples
- tight bend radii
Do Not:
• Do not use connecting hardware that is of a lower category than
the cable being used.
• Do not create multiple appearances of the same cable at several
distribution points (called bridged taps).
• Do not over-tighten cable ties, use staples, or make sharp bends
with cables.
• Do not place cable near equipment (e.g., generators, transformers,
engines, medical equipment, etc.) that may generate high levels
of electromagnetic interference.
• Do not exceed 90° bend.
Important Note: Installed UTP cabling shall be classified by the least
performing component in the link.
