  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. 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!! TIA

  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

  8. TIA TR-42 • “Additional Five” Subcommittees • Merged from FO-4 • TR-42.11 Optical Systems • TR-41.12 Optical Fibers and Cables • TR-42.13 Passive Optical Devices and Components • TR-42.15 Fiber Optic Metrology • New Subcommittee • TR-42.16 Bonding and Grounding

  9. TIA TR-42 • Membership • Consultants • End users • Manufacturers • Press • Government • Volunteers • Leadership is elected every 2 years

  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 NEW568-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 • ANSI mandates a 5-year life for published standards • Revised, reaffirmed or withdrawn • TIA-568B published May 2001 • 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 Generic Cabling • 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
