526-14A (Optical Power Loss Measurement of Installed Multimode
Fiber Cable Plant)
This
document establishes preferred measurement principles and
practices to assure that meaningful data describing the
optical loss performance of installed cable plant can be
obtained. It is not intended for component testing, nor
does it define those elements of an installation that must
be measured. Establishment of requirements for installation,
maintenance, repair or conformance testing is left to
the specifier of this test method.
TIA
526-7 (Optical Power Loss Measurement of Installed Single
Mode Fiber Cable Plant)
The intent of this procedure is to ensure that meaningful
data describing the optical loss performance of installed
single-mode cable plant can be obtained. It is not intended
for component testing, nor
does it define those elements of an installation that must
be measured. The document that invokes this procedure shall
establish the requirements for installation, maintenance,
repair and conformance testing.
TIA
568A - 1995 (Commercial Building Telecommunications Wiring
Standard)
This standard specifies a generic telecommunications cabling
system for commercial buildings that will support a multiproduct,
multivendor environment. It also provides information that
may be used for the design of telecommunications products
for commercial enterprises. The purpose of this standard
is to enable the planning and installation of a structured
cabling system for commercial buildings. Installation of
cabling system for commercial buildings. Establishes technical
and performance criteria for cabling system configurations
and interfacing and connecting their respective elements.
Incorporates all the relevant information from TIA 568,
TSB 36, TSB 40, and TSB 53.
TIA
568A-A1 - 1998 (Delay and Delay Skew)
This
addendum to 568-A describes and specifies requirements for
propagation delay and delay skew in cables, components,
basic links and channels.
TIA
568A-A2 - 1998 (Miscellaneous Changes)
Modifications
and updates to TIA568A. The most important change was the
requirement for testing connecting hardware with both common
and differential mode terminations.
TIA
568A-A3-1998 (Bundled and Hybrid Cables)
Revised
requirements for bundled and hybrid cables.
TIA
568A-A4 - 1999 (Patch Cords)
Defines
and specifies NEXT and return loss requirements for patch
cables.
TIA
568A-A5-1999 (Additional Transmission Performance Specifications
for Enhanced Category 5 Cabling)
Provides
performance requirements for Enhanced Category 5 (Category
5E) components, cable, and links. It includes all the
measurements in TSB-67 and TSB-95, but to
stricter performance levels. It also includes power
sum NEXT. All measurements are to 100 MHz.
TIA
568B.1-2000 (Commercial Building Telecommunications Wiring
Standard)
This
is a major new standard release that updates and replaces
the following standards and bulletins: TSB67, TSB72, TSB75,
TSB95, TIA568A, TIA568A addendum's 1,2,3,4, and 5. Important
additions include Category 5E performance levels, 50/125mm
fiber and allowance for alternate fiber connectors other
than the SC. Category 5E becomes the minimum accepted
performance level. Category 5 is now history.
TIA
568-B.2 (100 Ohm Twisted-Pair Cabling Standard)
Technical
content on 100 ohm twisted-pair cabling that is referenced
by TIA 568-B.1
TIA
568-B.3 (Optical Fiber Cabling Standard)
Technical
content on optical fiber cabling that is referenced by TIA
568-B.1
TIA
568-B.4 (Shielded Twisted-Pair Cabling Standard)
Technical
content on shielded twisted-pair cabling that is referenced
by TIA 568-B.1
TIA
569A-1995 (Commercial Building Standard for Telecommunications
Pathways and Spaces)
Specifies
design and construction practices for pathways and spaces
between commercial buildings.
TIA
570A-1998 (Residential and Light Commercial Telecommunications
Wiring Standard)
Specifies
residential cabling systems..
TIA
606 - 1994 (Administration Standard for the Telecommunications
Infrastructure of Commercial Buildings)
Administration
of communications wiring and connecting hardware, building
distribution systems, and grounding and bonding. Standardised
labeling and documentation requirements for generic cabling
in commercial buildings.
TIA
TSB-67-1995 (Transmission Performance Specifications for
Field Testing of Unshielded Twisted-Pair Cabling Systems
Defines
the basic link and channel. Specifies performance requirements
for the basic link and channel for wire map, length, attenuation,
and NEXT. Defines field measurement procedures and test
instrument requirements.
TIA
TSB-95-1999 (Additional Transmission Performance Specifications
for UTP)
TSB-95
outlines the min expected performance criteria for ELFEXT,
return loss, power sum ELFEXT, propagation delay, and delay
skew. Because it is a TSB, it is not a normative requirement.
TSB-95 provides guidelines to what the minimum installed
performance of legacy category 5 links can be expected.
IT managers should consider Category 5E as the minimum performance
level allowed. Category 5E is much better than TSB-95.
PN3727
Cat 6 Addendum-2000 (Category 6 component, cable, and link
requirements)
This
draft document was in its fifth revision as of May 1999.
At this time it is the most complete document providing
performance requirements for category 6 links, and is the
draft standard against which most manufacturers are verifying
product performance. As of early 2000, there is broad agreement
on numbers, but work needs to be completed on test methods.
This document has been delayed by ongoing work on TIA568B,
but now that most ballot issues have been resolved on TIA
568B, more attention will focus on completing the Category
6 document. Category 6/Class E performance requirements
will be specified in ISO/IEC 11801-2000, but this standard
will likely lag the TIA category 6 standard.
ISO/IEC
Standards Overview
The
first and most important document in this series is ISO/IEC
International Standard 11801 (IS1801).
ISO/IEC
14763-1 (Administration, documentation, records)
Describes
requirements for administration systems and documentation
of pathways, spaces, cables, terminations, and grounding
in accordance with ISO/IEC 11801. This document was approved
for publication in Feb/2000.
ISO/IEC
14763-2 (Planning and Installation practices)
Specifies
requirements for planning, specification, quality assurance
and installation of new cabling in accordance with ISO/IEC
11801. This document was approved for publication in Feb/2000.
ISO/IEC
14763-3 (Testing of optical fiber cabling)
Outlines
test procedures to be used to ensure that optical fiber
cabling, designed in accordance with ISO/IEC 11801 and installed
according to the recommendations of ISO/IEC 14763-2, is
capable of delivering the level of transmission performance
specified in ISO/IEC 11801. This document was approved for
publication in Feb/2000.
ISO/IEC
14763-4 (Testing of copper cabling)
This
project has been cancelled. IEC 61935 -1:1999 (Testing of
copper cabling) is to be referenced instead.
IEC
61935-1: 1999 (Testing of copper cabling)
Specifies
reference measurement procedures for cabling parameters
and requirements for field tester accuracy to measure cabling
parameters specified in ISO/IEC 11801.
IEC
61935-2 :2000 (Testing of copper cabling)
Specifies
requirements for laboratory testing of modular plug cords.
ISO/IEC
IS11801 -1995 (Generic Cabling for Customer Premises)
This
document has been the international standard for generic
cabling requirements in customer premises since 1995. However,
it has largely become obsolete for the following reasons:
It uses obsolete links definitions such as the 'cabling
link' (replaced by the Permanent Link) It does not specify
normative return loss requirements It does not address new
measurements such as ELFEXT, delay skew or PSNEXT It does
not address work area or patch cord performance Class D
requirements defined in this standard do not support ATM
155 Mbps networks
IS11801 is undergoing extensive revisions and is being updated
with ISO/IEC 11801 Proposed Draft Amendment 3 (ISO/IEC PDAM3).
ISO/IEC
IS11801 AM2 -1999 (Generic Cabling for Customer Premises)
This
is a major update to IS11801-1995. It adds requirements
for new measurements, defines the Permanent Link and Channel,
removes many ffs's (for future study), and provides more
detail. Another important change is Class D requirements
have been toughened and are now closer to TIA Cat 5E requirements
(but different). This has the interesting implication that
a link tested and in conformance to Class D in 1998 could
be tested against AM2 Class D in 1999 and fail, even though
the link has identical performance. Thus, in specifying
conformance to IS11801 it is critical to ensure you clarify
whether you require conformance with IS11801-1995 or IS11801
AM2.
Concurrently with the AM2 work, extensive revisions to include
Cat 6/Class E and Cat 7/Class F are in development. A complete
rewrite in the year 2000 incorporating these additions is
expected.
ISO/IEC
11801 2nd Edition - 2000 (Generic Cabling for Customer Premises)
