  1. 1. Convergence: Is Your Network Ready? The Growing Value of Cabling Systems
  2. 2. Trivia • What is the significance of the following number? • 340,282,366,920,938,463,463,374,607,431,768,211,456 • (340 undecillion, 282 decillion, 366 nonillion, 920 octillion, 938 septillion, 463 sextillion, 463 quintillion, 374 quadrillion, 607 trillion, 431 billion, 768 million, 211 thousand and 456) AMP NETCONNECT / page 2 /
  3. 3. Trivia • Equals 2128 • 128-bit address: 2128 or over 340 undecillion – 340,282,366,920,938,463,463,374,607,431,768,211,456 • Possible Number of IP Device Addresses (IPv6) – IPv4, has (“only”) fewer than 4.3 billion unique IP addresses AMP NETCONNECT / page 3 /
  4. 4. Industry Trends • IP Technology is Exploding – Cheaper and smaller devices to create data • Cameras (still and video), microphones, monitoring devices – New IP devices • TVs, NAS devices, RFID, building automation controls, refrigerators – Possible Number of IP Device Addresses (IPv6) • 340,282,366,920,938,463,463,374,607,431,768,211,456 – That’s 665,570,793,348,866,943,898,599 unique IP addresses for every square meter on the planet AMP NETCONNECT / page 4 /
  5. 5. Industry Trends • Data is Proliferating – Recorded Images and Video – Live Video and Audio • Vlogs, YouTube, MySpace, Streaming – Monitoring, Trending, RFID Data • Memory is Cheaper • File Sizes are Getting Larger – More than doubled in three years* • In May 2002, the average file size being shared on a P2P network was 3.22 megabytes; In June 2005, it was 8.92 MB – Pyramid Distribution of Files *Source: www.Forbes.com “File Size On P2P Nets Explodes” by Lisa DiCarlo, 06.08.05 AMP NETCONNECT / page 5 /
  6. 6. Industry Trends • Digital Convergence – VoIP – IPTV (SDTV & HDTV) • 100Mbps Internet connections • Video-On-Demand (HD Movie Downloads) • Digital Media Center (Windows Vista) – Streaming video, music, photos, home automation • FTTX: Fiber/triple-play deployment – Verizon FIOS • Fiber to the Apartment – AT&T U-Verse AMP NETCONNECT / page 6 /
  7. 7. Industry Trends • Broadband Coaxial Network Vs. Ethernet MPEG-2 Channel Capacity – CATV: 5.2Gbps (256-QAM modulation);275 HDTV channels – Ethernet: GigE: 50 HDTV channels; 10GigE: 500 HDTV Channels • HD-DVD / Blu-Ray – Storage capacity: • HD-DVD: 15/30GB (sgl/dual layer) • Blu-Ray: 25/50GB (sgl/dual layer) AMP NETCONNECT / page 7 /
  8. 8. Industry Trends • More, Larger, Faster • 340,282,366,920,938,463,463,374,607,431,768,211,456 – 340 undecillion, 282 decillion, and change… • Constant change and innovation brings more devices requiring more capability AMP NETCONNECT / page 8 /
  9. 9. Network Trends • Latency is Increasing – Larger Files Take Longer to Move • 80G iPod takes 13 minutes to transfer at 100Mb/s – Searching larger databases takes more time – Cost of latency is increasing as file sizes increase • A company with annual revenue of $10M and 100 employees averages 10 minutes, per day, per employee of latency cost – that’s $271,000 annually just in time spent waiting for file movement – Networks capable of greatest speeds have lower latency costs AMP NETCONNECT / page 9 /

AMP NETCONNECT / page 12 /
  13. 13. Cabling Is An Asset • Cabling Becomes an Expandable Asset – Expandable utilization of existing infrastructure instead of overlaying individual technologies – Mechanism for Cost Reduction • More effective use of bandwidth, servers and storage • Not a line item for cost reduction • Cabling Becomes a Vital Asset AMP NETCONNECT CABLE AMP NETCONNECT / page 13 /
  14. 14. Convergence: What’s It Mean For You? • The key to making yourself valuable is making the infrastructure valuable • The key to making the infrastructure valuable is to make the infrastructure capable AMP NETCONNECT / page 14 /
  15. 15. NETCONNECT Enhanced Category 5 Cabling System It’s Like Category 5… Only Better!
  16. 16. THE ENHANCED “ISSUES”
  17. 17. Data Rate ≠ Bandwidth • 100 MHz is NOT the same as 100 Mbps • Bandwidth is: – The frequency range across which components and systems are specified – Not based on a particular application or data rate – Limited by useable ACR (not data rate) – 1 MHz to 100 MHz per Cat 5e specifications AMP NETCONNECT / page 17 /
  18. 18. Data Rate ≠ Bandwidth • Data Rate – How fast you can pump data through a system with a given bandwidth – Dependent on the application and encoding scheme AMP NETCONNECT / page 18 /
  19. 19. Performance Characteristics • Three configurations to measure – Components – Link – Channel • Important characteristics – Near End Crosstalk (NEXT) – Equal Level Far End Crosstalk (ELFEXT) – Attenuation – Return Loss – Skew AMP NETCONNECT / page 19 /
  20. 20. Link and Channel Configurations Link = Outlet to Patch Panel or Cross Connect Channel = Network Interface Card to Hub AMP NETCONNECT / page 20 /
  21. 21. Performance Characteristics • Key Performance Parameters – Near End Crosstalk (NEXT) – Attenuation – Attenuation to Crosstalk Ratio (ACR) Pair 1 XCVR XCVR Pair 2 NIC HUB
  22. 22. NEXT, Attenuation and ACR Coupled NEXT Noise NIC HUB Transmitter Receiver Receiver Transmitter Attenuated Transmitted Signal Signal ACR Attenuated Signal NEXT Noise
  23. 23. The Move to Cat 5e June 1996 - IEEE 802.3 begins work on Gigabit Ethernet Questions raised about unspecified parameters of Category 5 Also need to standardize manufacturers’ claims of performance in excess of Cat 5
  24. 24. Addendum 1 September 1997 - TIA/EIA-568-A-1: Propagation delay and skew requirements added for Cat 5 cable.
  25. 25. Effects of Skew T1 T2 Fastest Pair 1 Pair 2 Pair 3 Pair 4 NIC HUB Slowest • Skew is the difference in propagation delay between the fastest and slowest pairs in a cable. • Proposed requirement: <45 ns @ 100 MHz (Channel)
  26. 26. Two More Addenda Drafted • SP-4194 • SP-4195 – Proposed Addendum No. 4 to – Proposed Addendum No. 5 to 568-A 568-A – Additional Transmission – Additional Transmission Performance Specifications for 4- Performance Specifications for 4- Pair 100 Ohm Category 5 Cabling Pair 100 Ohm Enhanced Category 5 Cabling
  27. 27. Addendum vs. TSB • The TIA changed its position on SP-4194 – Can’t place new specifications on existing components and installations – Information will be published as TSB 95 • Informational purposes • Changes from “shall” to “probably”! AMP NETCONNECT / page 27 /
  28. 28. TSB95 - Additional Cat 5 Specifications “The development of certain high-speed applications has brought to the attention of the TIA the need for additional transmission requirements such as return loss and far end crosstalk (FEXT). These parameters are needed by system designers for applications that utilize all four pairs in the cable for full duplex transmission.” “Although these are new specifications, the existing worst-case, two-connector topologies compliant with TIA/EIA-568-A are expected to meet these requirements. Other topologies are supported as long as they meet the ELFEXT and Return Loss requirements of this document.”
  29. 29. Two-connector Topologies? Other Topologies. . . (i.e. with cross-connect and/or transition point)

  32. 32. SP-4195 - Enhanced Cat 5 “The development of certain high-speed applications has brought to the attention of the TIA the need for additional transmission requirements such as multi- disturber NEXT, return loss and multi-disturber far end crosstalk (FEXT). These parameters are needed by system designers for applications that utilize all four pairs in the cable for simultaneous bi-directional transmission.” “Addendum 5 for category 5e cabling provides higher performance over a minimally compliant category 5 channel and recognizes advances in cabling technology.”

  36. 36. What Do You NEED to Run 1000BASE-T? IEEE 802.3ab Physical layer specification for 1000 Mb/s operation on four pairs of Category 5 or better balanced twisted pair cable (1000BASE-T) 40.8 Link Segment Characteristics 1000BASE-T uses a duplex transmission system. Four full duplex channels are required to transport data between two PMDs. Each duplex channel supports an effective data rate of 250 Mbps in each direction simultaneously. The term ‘link segment’ used in this clause refers to four duplex channels and the term ‘duplex channel’ will be used to refer a single channel with full duplex capability. Specifications for a link segment applies equally to each for the four duplex channels. 1000BASE-T is designed to operate over a 4-pair Category 5 cabling system.
  37. 37. Designed to Operate Over Cat 5, BUT. . . ANNEX 40A Additional Cabling Design Guidelines Although the 1 Gb/s specification described in Clause 40 was designed to operate over 4-pair Category 5 cabling systems as specified in ANSI/TIA/EIA-568-A and ISO/IEC 11801, there are additional steps that may be taken by network designers that will provide additional operating margins and ensure the objective BER of 10-10 is achieved. •Power Sum NEXT •Defined but not spec’d higher than Cat 5 •Power Sum ELFEXT •Spec’d in TSB95 (Cat 5) •Don’t use 25-pair •Don’t use crossconnect or transition point
  38. 38. Cat 5 and Cat 5e – Bottom Line • Cat 5 will probably run Gigabit Ethernet. – But maybe only with two connectors! • Cat 5e provides the extra margin required to ensure 1000BASE-T support with 4-connector channels. – It’s been ratified as TIA/EIA-568-A-5. • Cat 5 is not recommended in TIA/EIA-568-B. – It’s been relegated to an annex. • Cat 5e is the minimum recommendation for data cabling.

  41. 41. THE ENHANCED “BENEFITS”
  42. 42. NETCONNECT Enhanced Cat 5 ENHANCED BENEFITS • “Future-proofing” – Gigabit Ethernet will push standard Cat 5 to the limit. In order to support 1000BASE-T and still have freedom to use more than two connectors, Cat 5e is recommended. • Cat 5e will be the recommended minimum performance category for data in the next revision of TIA/EIA-568. • Insurance against installation problems and ambient electrical noise • More reliable operation of existing LANs up to 155 Mbps AMP NETCONNECT / page 42 /

  48. 48. What About Category 6? • Cat 6 was originally a German DIN standard addressing shielded cabling systems with performance out to 600 MHz. • Category 6/Class E was “re-proposed” by ISO/IEC 11801-A as specifying positive channel performance to 250 MHz. – Both the ISO and the TIA are now working on Cat 6 and its frequency range has been extended to 250 MHz. • The German DIN Cat 6 is now Cat 7/Class F, also under development by the ISO.

  51. 51. Why Install Category 6? • Performance Level: 250 MHz • Applications: – All existing UTP applications including 1000BASE-T – Forms the basis on which the next generation of twisted pair applications will be developed • 25-Year System Warranty: Category 6
  52. 52. The AMP NETCONNECT Category 6 System • Category 6 performance confirmed by independent testing – Intertek Testing Services (ETL SEMKO) • End-to-end system engineering ensures optimum performance – Critical at 250 MHz Category 6 bandwidth – Look at the system performance - not just cable • Single vendor solution and warranty – No shifting “partnerships”
  53. 53. The Channel The most important performance characteristics are those of the channel. The channel numbers represent the performance of the entire cabling system. AMP NETCONNECT / page 53 /
  54. 54. Channel Performance • In order to be Cat 6 compliant, the entire cabling system must meet all of the requirements when configured in the worst-case configuration. • The worst-case configuration allowed by the TIA is the 100-meter, 4- connector channel. • On March 5, 2001 Intertek Testing Services tested AMP NETCONNECT plenum and non-plenum channels constructed from production Category 6 products. • The following slides show the absolute worst performance at each frequency point from those tests.

  57. 57. What is the difference between Cat 5e, cat 5E and Cat 6? • Signal to noise ratio • Bandwidth used to test the cable The first difference is the most important. Cat 6 Cat 6 is twelve times less "noisy", than Cat 5e. The better the signal to noise ratio is on your network, the less often this happens. AMP NETCONNECT / page 57 /
  58. 58. What is the difference between Cat 5e, cat 5E and Cat 6? Con’t • testing across a bandwidth of 100 MHz. The Cat 6 standard calls for testing across a bandwidth of 250 MHz. • The reality is that most computers and networking equipment only transmit across a frequency range of 100 MHz. (In the future, of course, actual utilization of greater bandwidth may become more common.) AMP NETCONNECT / page 58 /
  59. 59. What is the difference between Cat 5e, cat 5E and Cat 6? Con’t • Many cable companies tout the high bandwidth of their cable. Some even test up to as high as 700 MHz. It sounds great for marketing, but the truth is that the MHz rating is not the same as speed. • All cable rated Cat 5e or Cat 6 is capable of Gigabit Ethernet. The MHz rating is just the frequency range used for testing the cable. • Source: Network Know how – Will Hunt AMP NETCONNECT / page 59 /
  60. 60. Shielded 10G Cabling Infrastructure A Highly Capable, Valuable, Expandable Asset
  61. 61. Cabling Options for 10GbE • Fiber – Highest performance – Best future-proofing – Comparable cost to copper – Density – small cable diameters, small connectors – Ease of installation – NE/NP connectors – Cost of electronics – no migration path with existing electronics • This typically steers the decision in the direction of copper… AMP NETCONNECT / page 61 /
  62. 62. Cabling Options for 10GbE • Copper – Familiarity – Provides necessary performance – PoE and PoE Plus – Migration path with existing electronics • Leads to Unshielded vs. Shielded… AMP NETCONNECT / page 62 /
  63. 63. Advantages of a Shielded 10 GbE Solution • Equitable cost (compared to 6A UTP), both for materials and for labor & installation • Significantly greater Shannon Capacity than Category 6A UTP • Alien Crosstalk prevented by shield, not by space – Eliminates effects of AXT • Great fit for “secure” applications • Application-friendly in all environments – EMI & RFI resistant in noisy environments • Fewer spurious spikes and system interruptions • Noise reduction from non-cable sources • Shielded has been commercially available for years AMP NETCONNECT / page 63 /

  70. 70. Alien Crosstalk (AXT) • AXT is the undesired coupling of signals between adjacent cables • AXT is a new parameter to consider, yet it is the most critical parameter for 10G • AXT cannot be cancelled by Digital Signal Processing (DSP) technology • AXT can ONLY be prevented or mitigated by a shield, space, or glass AMP NETCONNECT / page 70 /
  71. 71. Industry comments about Alien Crosstalk • This noise source from adjacent cables, however, cannot be cancelled effectively by Digital Signal Processing. The solution is to provide increased isolation of cables from one another, either by increased separation, use of shielding, or improved cable constructions that reduce ANEXT. • The IEEE has determined that alien crosstalk is the main electrical parameter limiting the performance of the structured cabling system, when applied to 10 Gigabit transmission lines. • Presentations given in the 10GBASE-T task force have identified alien crosstalk to be the most dominant noise source. Unlike other noise impairments, alien crosstalk is very difficult to mitigate using advanced digital signal processing (DSP) algorithms due to its random statistical nature. AMP NETCONNECT / page 71 /
  72. 72. AXT Considerations for UTP and STP • Shielded cables provide CONSIDERABLE headroom for AXT! – Current pair-to-pair performance parameters will be more stringent as we move toward 500 MHz – However, AXT performance will be the main consideration! • Unshielded cables will be marginal at best… – Space is the only way to mitigate the effects of AXT • Addendum 11 allows for cables up to .354” OD (instead of .250”) • Larger cables provide better AXT performance, but take up more space • Unshielded Cat 6A cables running 10G shouldn’t be mixed in a pathway with other cable types (ie – Cat 6 or Cat 5e) – Not specifically addressed by the standards, but still very much a concern for unshielded cables – Not an issue for shielded cables AMP NETCONNECT / page 72 /
  73. 73. IEEE 802.3an – Cabling Types AMP NETCONNECT / page 73 /
  74. 74. The Space of a Shielded Solution • Port density equivalent to current Cat 6 • Shielded cables have smaller OD than Augmented Category 6 cables • UTP ANEXT reduction through spacing… – Make the cable jacket thicker or use two cable jackets • More expensive and stiffer cable – Loss of density in conduits, cable trays, cable management – Not just horizontal cable – but also patch cords! AMP NETCONNECT / page 74 /
  75. 75. Size Comparisons • Single cable comparison • We work in a world of cable BUNDLES! Cat 5e UTP Cat 6 UTP Cat 6A F/UTP Cat 6A UTP AMP NETCONNECT / page 75 /
  76. 76. Size Matters… • How does cable size really affect your pathway costs? – Conduit fill – based on 40% fill ratio – 40% more cables in a conduit Conduit F/UTP 6A UTP Size 7.6mm (.300") 9.0 mm (0.354") 2 18 13 3 40 29 4 71 51 – Patch cord comparison – F/UTP compared to U/UTP AMP NETCONNECT / page 76 /
  77. 77. Installing a Shielded Solution • Shielded cable termination time is perceived to be longer than UTP equivalents (e.g. Cat 6). THIS IS SIMPLY NOT TRUE!! – New tooling options and connector technologies are available to dramatically simplify terminations and decrease termination times • Just like NE/NP fiber connectors, the new termination technology dramatically reduces the cost of shielded cabling systems • A ninety-second shielded jack!! AMP NETCONNECT is the only company that has simplified shielded connections to this extent AMP NETCONNECT / page 77 /
  78. 78. Installation of the AMP-TWIST® Jack in 90 seconds or less!! 1 3 Press the clamp and insert cable Locate the rear housing into the through hole front housing 2 4 Lace the wires into the slots Place the jack into the tool and according to wiring pattern squeeze the handle all the way down. Finished!! AMP NETCONNECT / page 78 /
  79. 79. Installing a Shielded Solution: XG Shielded Patch Panels • Improved labeling – Integrated dual purpose labeling space • Paper labels with clear plastic cover • Black plastic cover for adhesive labels – Labels can be applied to covers on a flat surface and then snapped on to the panel – Icons – Port numbers AMP NETCONNECT / page 79 /
  80. 80. Installing a Shielded Solution: XG Shielded Patch Panels • Integrated grounding/bonding technology – Patent-pending bonding bar to simplify grounding/bonding • Snap in the jack and it’s done! • Fast and easy – No time consuming or complicated installation processes – Paint piercing star washer completes bonding path from patch panel to rack Integrated bonding bar completes metallic connection from jack to patch panel for easy grounding! AMP NETCONNECT / page 80 /
  81. 81. Installing a Shielded Solution • The smaller diameter of shielded cables make them easier to pull/install than the 6A UTP cables – Bend radius concerns – the smaller the cable, the less space required to “turn” it • Field testing of alien crosstalk on shielded cabling systems not required – Much different story for unshielded AMP NETCONNECT / page 81 /
  82. 82. Field Testing of Alien Crosstalk on UTP • Not required, but suggested • Time consuming • Sample testing AMP NETCONNECT / page 82 /
  83. 83. Grounding and Bonding • Grounding and bonding needs to be done properly for BOTH SHIELDED AND UNSHIELDED systems, but is easily and routinely accomplished! – Same procedures need to be followed on unshielded installations as well as fiber! • Definitions – Grounding - Establishing a conducting connection between an electrical circuit or equipment and the earth. (Electrical Contractor) – Bonding: The permanent joining of metallic parts to form an electrically conductive path that will ensure electrical continuity. (Telecommunications Contractor) AMP NETCONNECT / page 83 /
  84. 84. Grounding and Bonding • Grounding systems should be common and have one grounding electrode to ensure zero potential • Racks and cabinets should be bonded • Permanent link should be bonded at one end – the closet end – Best bond is to the structural steel • Shielded cable assemblies effectively bond at both ends – Maintains effectiveness of shield performance – Ensuring no leakage from end to end AMP NETCONNECT / page 84 /

What ground loop? • For years, network switches have been tied into two bonding Electrical TGB Panel points without any negative effects • A common grounding electrode eliminates potential for ground loops 7x 8x 9x 10x 11x 12x 7x 8x 9x 10x 11x 12x Ethernet C 7 8 910 12 11 A 1 2 34 5 6 1x 2x 3x A 4x 5x 6x 1x 2x 3x 4x 5x 6x B • Multiple bonding points have not caused an issue for network switches, multiple bonding points will not cause any issues for the cabling system AMP NETCONNECT / page 86 /
  87. 87. Methods for Bonding Patch Panels • Star washers – Pierce paint on panels to provide a bond from panel to rack with the mounting screws (shown at right) – Alternatively, place star washer between the panel and the rack • Grounding lugs – Attach to panels and daisy chain panels together and attach to ground AMP NETCONNECT / page 87 /
  88. 88. Is It Really Shielded? • Quick, easy, and consistent terminations • Grounding and bonding easily accomplished • Patch panels look like…well, they look like a normal panel AMP NETCONNECT / page 88 /
