1 TIA TR-42 Telecommunications Cabling Systems Update BICSI January 2009

2 Introduction Herb Congdon –Chair, TIA TR-42

3 TR-42 Overview Herb Congdon

4 TIA Telecommunications Industry Association

5 TIA A “full service trade association representing providers of communications and IT products and services for a global marketplace” An ANSI-accredited Standards body in information and communications technology (ICT) Over 10 main formulating plenary committees and several TAGs for international Standards bodies We’re #4!!

6 TIA - Standards Membership –Member Companies –Former Member Companies –Individuals (ECP) –Liaisons –Government

7 TIA TR-42 “Original Nine” Subcommittees –42.1 Commercial Building Cabling –42.2 Residential –42.3 Pathways & Spaces –42.4 Outside Plant –42.5 Terms, Definitions and Abbreviations –42.6 Administration –42.7 Copper Components –42.8 Optical Fiber Components –42.9 Industrial

10 International De-facto Standardization Organization

11 How TR-42 Works Herb Congdon

12 Process New Proposals or Timed Actions Task Group Draft Developed Documents Balloted Consensus-based Resolution Re-ballot As Necessary Documents Released for Publication Documents Approved for Publication

13 The NEW 568-C.0 Standard Herb Congdon

14 568-C – Why? ANSI mandates a 5-year life for published standards –Revised, reaffirmed or withdrawn TIA-568B published May 2001 –>5 years ago Many addenda since publication –6 addenda to 568-B.1 –10 addenda to 568-B.2 –1 addendum to 568-B.3

15 Improvement Opportunity Complaint: Duplicated information –Cause: Synchronizing and updating multiple documents is complicated –Solution: Centralize common information

16 Improvement Opportunity Complaint: Lengthy development of new Standards –Cause: Creating new premise Standards is unnecessarily repetitive –Solution: Establish common information in one document

17 Improvement Opportunity Complaint: Gaps in Standards Coverage –Cause: Standards tend to be too specific –Solution: Start with common information applicable everywhere, then manage exceptions and allowances specific to the premise

18 The Plan Coffee Hot Chocolate

19 Solution: A Generic Cabling Standard A new standard for generic cabling - 568- C.0, Generic Telecommunications Cabling for Customer Premises –The foundation for future Standards –The cabling Standard when documents specific to a premises are not available –Consolidates common information in one document Content from 568-B.1 & addenda split between C.0 and C.1

20 Splitting 568-B.1 568-B.1 (94 pgs) 568-C.0 Generic (~60 pgs) 568-C.1 CBC (~35 pgs)

21 568-C Series Documents One New Standard (568-C.0) –568-C.0 – generic structured cabling Three Revisions –568-C.1 – commercial building cabling Office-oriented buildings –568-C.2 – copper cabling components –568-C.3 – fiber cabling components

22 Three Document Types –Common Standards Generic Pathways & Spaces Administration, etc. –Premise Standards Commercial Building Residential Data Centers, etc. –Component Standards Copper Optical Fiber

23 Looking Forward Over the next 3-5 years –Other premises Standards will be revised to acknowledge 568-C.0 List appropriate exceptions and allowances –Existing common Standards modified to broaden scope Replace “commercial building” focus and terminology Become more generic in nature New Standards will be built on the foundation of 568-C.0

24 568-C Series Documents 568-C.0 – generic structured cabling – RELEASED (October) 568-C.1 – commercial building cabling – RELEASED (October) 568-C.2 – copper cabling components – expected in 2009 568-C.3 – fiber cabling components - PUBLISHED

25 568-C.0 Generic Cabling

26 568-C.0 Establishes How a Star Network Topology Is Constructed –Does not need to be repeated in every document –Premise standards define appropriate allowances and exceptions

27 568-C.0 Generic Cabling 568-C.0 Establishes Cabling Requirements –Applicable to all premise Standards unless noted as an exception or allowance

28 568-C.0 Generic Cabling 568-C.0 Establishes Generic Cabling Nomenclature –Cabling Subsystem 1, Cabling Subsystem 2 and Cabling Subsystem 3 –Distributor A, Distributor B, Distributor C and Equipment Outlet –Specific nomenclature assigned in premise Standards

29 568-C.0 - Generic Cabling Topology Part 1 of Figure 2

30 568-C.0 - Generic Cabling Topology Part 2 of Figure 2

31 568-C.0 – Generic Cabling 568-C.0 Incorporates some of the 568-B.1 Addenda –Centralized cabling, patch cord bend radius, etc. 568-C.0 Collected Common Information from 568-B.1 and others –Choosing media, Cabling lengths –Bonding and grounding, Polarity –Installation requirements –Application support tables –Optical fiber testing & limits NOTE: balanced twisted-pair testing and limits will be in 568- C.2

32 568-C.0 – Technical Changes Installation minimum bend radius for balanced twisted-pair cable –Changed to 4x cable OD for both shielded and unshielded Note: Worst case minimum bend radius is now 1.5 inches (not 1.0 inch) since the largest allowable cable OD is 0.354 inches (per 568-B.2-11) Adds Augmented Category 6 (shielded and unshielded) as a recognized medium

33 568-C.0 – Technical Changes Patch cable bend radius for balanced twisted-pair cabling –Changed to “1x cable OD” from “0.25 inches” Single-mode optical fiber allowed in the horizontal Simplex optical fiber

34 The 568-C.1 Revision Herb Congdon

35 568-C.1 – Commercial Building Builds on information in 568-C.0 Contains appropriate allowances and exceptions to 568-C.0 that are specific to office-oriented commercial building cabling

36 568-C.1 – Commercial Building Retains use of 568-B.1 nomenclature –Main Cross-connect (Distributor C in 568-C.0) –Interbuilding backbone cabling (Cabling Subsystem 3 in 568-C.0) –Intermediate Cross-connect (Distributor B in 568-C.0) –Intrabuilding backbone cabling (Cabling Subsystem 2 in 568-C.0) –Horizontal Cross-connect (Distributor A in 568-C.0) –Horizontal cabling (Cabling Subsystem 1 in 568-C.0) –The Telecommunications Outlet (Equipment Outlet in 568-C.0)

40 568-C.1 – Technical Changes Inclusion of centralized cabling in the main body of document A recommendation to select 850 nm laser- optimized 50/125 µm as the multimode fiber for commercial buildings

41 568-C.1 – Technical Changes Removal of common information (this was moved into 568-C.0) Removal of 150-Ohm STP cabling Removal of category 5 cabling Removal of 50-ohm and 75-ohm coaxial cabling

42 568-C.1 – Technical Changes Removal of balanced twisted-pair cabling performance and test requirements (these will be in the ANSI/TIA-568-C.2 document) –NOTE: optical fiber cabling performance and test requirements in 568-C.0
