1 1 Optical Fiber Premises Standards News & Trends Herb Congdon Tyco Electronics Updated: October 2005

2 2 IEEE Ten Gigabit Ethernet (10GBASE-F) Published as IEEE802.3ae in June 2002 Ten Gigabit Ethernet (10GBASE-LRM) 10GBASE-LRM (802.3aq) 10G using one SM laser source Objective is a less-expensive solution for legacy MM fiber Reach is an issue 220m, not 300m

3 3 TIA TR-42 UPTI 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 Most recent meetings held Oct 2-7, 2005

4 4 TR-42.1 Commercial Building Cabling Completed Work for 568-B.1 Addendum 3 (Supportable Distances and Channel Attenuation for Optical Fiber Applications by Fiber Type) published 2/03 100BASE-SX and 10GBASE-F included Addendum 4 (Recognition of Category 6 and 850nm Laser-Optimized 50/125 µm Multimode Optical Fiber Cabling) published 2/03 Allows the 850nm Laser-Optimized 50/125 µm

5 5 TR-42.1 Commercial Building Cabling Completed Work on 568-B.1 Addendum 5 (Telecommunications Enclosures) is released for publication This addendum says how a TE can be used in a 568-B.1-compliant manner Allows fiber further into the network

6 6 TE - Traditional Horizontal Cabling HC in the TR Optical Fiber Backbone Horizontal cabling 4-pr. UTP cables TO Offices Cubicles

7 7 TE - Concept Implementation HC in the TR Optical Fiber Backbone Optical Fiber Backbones e.g. TE TE TO Cubicles Horizontal cabling Offices

8 8 TR-42.1 Commercial Building Cabling TIA-942, Telecommunications Infrastructure Standard for Data Centers Network Distribution Nodes More commonly referred to as the Data Center & SAN Standard Available for purchase since April 1, 2005 ($250) Important Fiber Issues Single-mode, 62.5-micron, 50-micron and 850nm Laser-optimized fiber allowed (latter is recommended) 300 meter pull-through allowed for centralized fiber networks (not 90m as in 568B)

9 9 TR-42.3 Pathways and Spaces Work Completed in February 569-B is now published & available ($163) Final editorial change approved in June 2004 Published as a TIA Standard TIA-569-B (Pathways and Spaces) defined telecommunications enclosures (TEs)

10 1 0 TR-42.7 Copper Cabling Components Recently Completed Work TIA-568-B.2-11 Maximum Diameter Of SCTP Cable To.354 Inches was sent to publish in the October meeting 2-fiber zipcord: 0.11 x 0.22 inches 2-fiber mini-zipcord: 0.08 x 0.16 inches 2-fiber DUAL: 0.19 inches 2-fiber QUAD: 0.19 inches

11 1 1 TR-42.8 Optical Fiber Cabling Components Recently Completed Work for 568-B B.1-7 Guidelines For Maintaining Optical Fiber Polarity with Systems Utilizing Array Connectors Supports use of array connectors (MPO) Started in support of Data Center Standard

12 1 2 TR-42.8 Optical Fiber Cabling Components New Project 568-C.3 revision project started

13 C?!?! Just what do you think you re doing? TIA mandates that Standards be revised, withdrawn or reaffirmed every 5 years The revision process takes about two years or so TIA-568B was published in May of 2001 (over four years ago) so...better get started! Projects opened for 568C.0 568C.1 568C.2 568C.3

14 1 4 What s this about 568-C.0? A better way to do things in TR-42? Types of Premises Standards Commercial, Residential, Outside Plant, Industrial (eventually), Data Centers Components Standards Copper UTP, Coaxial Cable, Optical Fiber, Connectors, etc. Practice Standards Pathways & Spaces, Administration TR-42 Subcommittee Chairs looked at what we were doing things and wondered how to do them better

15 1 5 What s this about 568-C.0? One thing we re doing is repeating information Can generate inconsistencies Requirements and documents that may not reflect the most recent information Document cycles complicate adoption of consistent information and revisions

16 1 6 What s this about 568-C.0? Several proposals considered Best Solution: Create a Generic Cabling Standard To serve as an umbrella document for all the types of premises standards Types of Premises standards would then list requirements specific to the type of premise

17 568-C.0: Generic Cabling 1 7 Since all the types of premises standards are based on the hierarchal star architecture, this document would outline the connection points and links Connection Points instead of spaces A (ex: Main Cross-connect) B (ex: Intermediate Cross-connect) C (ex: Telecommunications Room) D (ex: Consolidation Point) Links between connection points Level 1 (ex: intrabuilding cable) Level 2 (ex: interbuilding cable) Level 3 (ex: horizontal cable)

18 C.0: Generic Cabling Would also include other information common to several documents Choosing media Bonding and grounding Field testing Polarity etc.

19 1 9 So, the 568 Series would potentially be C.0: Generic Cabling 568-C.1: Commercial Building Cabling 568-C.2: Copper Cabling Components 568-C.3: Optical Fiber Cabling Components

20 C.0 Drawbacks Concerns about yet another Standard to purchase May be difficult to get finished in a timely manner May have a 4 to 5 year period before all other documents can be revised with recognition of this 568-C.0 What to do with Pathways & Spaces and Administration Standards?

21 C.0 Advantages Becomes a clearing house for common aspects of structured cabling Serves as springboard for new types of premises standards ex: Healthcare Facility Cabling Simplifies additions, deletions and revisions due to advances in technology

22 C.0 Today Still just a project proposed and approved Discussions are continuing on how to divide up the existing documents First draft may be released before October meetings Probably a cut-and-paste of existing documents

23 How could it look? 2 3 Existing documents (Standards, Addenda, etc.) will have to be parsed out into one of the new documents or left behind for the next revision

24 2 4 Examples - Addenda Addenda to 568-B.1 could roll into 568-C Seven approved or in ballot 1: Patch Cable Bend Radius C.0 (use) and C.2 (manufacture) 2: B&G for Screened TWP C.0 3: Annex E Revision (Fiber Design Param s) C.0 4: Cat 6 and 850nm LO 50-micron C.0 (use) and C.2/C.3 (mfg) 5: Telecommunications Enclosures C.1 6: DC Power (DTE) C.0 7: Array Connector Polarity C.0 (use) & C.3 (manufacture)

25 2 5 Examples - TSBs TSBs can be rolled into 568-C TSB-125 Reverse Pair Positioning Polarity C.0 & C.3 TSB-140 on fiber certification testing C.0 TSB on cabling bundles and loops C.0 & C.2

26 2 6 What happens with 568-C.1? Retains those requirements and guidelines specific to commercial building cabling Nomenclature (tends to be different across types of premises) Outlet number and location Allowable media (subset of all media)

27 2 7 How about 568-C.2? Retains content of 568-B.2 and related documents specific to the components and link performance May need to add coaxial cable (Data Centers, Residential, etc.)

28 How about 568-C.3? 2 8 Retains content of 568-B.3 and related documents specific to the components and link performance Already some agreements on changes to make Add in an indoor/outdoor cable reference (ICEA S ) and a drop cable reference (ICEA S ) Use when color is used to identify the fiber type... (color) should indicate (fiber type)... Separate out 50µm connectors and adapters so that the color black indicates 50µm, beige indicates 62.5µm, aqua indicates 850nm laser optimized 50µm mmf, blue indicates single-mode, and green for angled single-mode

29 2 9 What About the Other Documents? Although incongruous at first, the other standards documents will be revised to fit under the umbrella of 568-C C.0 will reference the components defined in C.2 and C-3 Practice Standards (Admin, Pathways and Spaces) may get rolled into Generic or remain as standalone

30 3 0 What s Next? Chairs group has matrix of all documents Table of contents with proposals for retaining or moving to another document Once satisfied, drafts for 568-C.0, 568-C.1, 568- C.2 and 568-C.3 will be created THEN the real fun can begin Proposed Schedule Drafts in December 2005 Ballots in 2006 Publish???

31 3 1 A respectful request... Your input is valuable to the process Please submit your comments, criticisms, gripes and other observations for consideration Next meeting is in late January
