1 Ethernet and UTP Cabling from 10BASE-T to 10GBASE-T Terry Cobb Avaya

2 Presentation Timeline Market Forecast Cabling Past and Present Ethernet and Cabling Cabling Installation Trends 10GBASE-T Cat 6 compared to Cat 5 Conclusion

3 Timeline (UTP Category 3-6) Often there is very little distinction between Category 5 and Category 5e Category 5e RL & ELFEXT are required Category 3 Category 5 Category 5e Category 6 Up until this point field testing of installed cabling was not defined 1995 TIA TSB 67 Field Testing 1999 TIA TSB 95 Category 5 RL & ELFEXT Up until this point field testing of installed cabling for RL or ELFEXT was not defined TIA TSB 36/40 Category TIA 568A Category 5 ISO Class D 1999 TIA 568-A-5 Category 5e 2002 TIA Category 6 ISO Class E ISO Class D = Cat 5e We are here BASE-T BASE-TX BASE-T GBASE-T

9 Ethernet History 100% Shipments % of Total UTP Ports/Cable 10BASE-T 100BASE-TX BASE-T BASE-T2 1000BASE-T BASE-T BASE-TX BASE-T CFI tolley_1_1102 (UTP ports)

10 Ethernet and Cabling 100% Shipments % of Total UTP Ports/Cable 1990 While Category 5 was replacing Category 3 Ethernet continued to support Category 3 Cat 5/4 100BASE-TX BASE-T BASE-T BASE-TX

11 Ethernet and Cabling 100% Shipments % of Total UTP Ports/Cable Category 6 follows the same trend and time line as Category 5 Cat 5/4 Cat TIA Category TIA Category 6 ISO Class E

12 Ethernet and Cabling 100% Shipments % of Total UTP Ports/Cable If Category 6 is replacing Category 5 why support Category 5 for 10GBASE-T 100BASE-TX Cat 5/4 Cat 6 10GBASE-T BASE-TX GBASE-T

13 How often is cabling replaced Software is replaced 2X compared to PC PC Cost Life Software Cabling LAN is replaced 2-3X compared to Cabling LAN

14 Why do customers replace cabling Building renovation Entire building is torn down and replaced Floors/sections of buildings are renovated Move or new tenant Cabling type doesn't meet new IT needs New tenant has different corporate wiring standard Work area move, additions, or changes Furniture clusters are rearranged around group/departments Walls and/or furniture are upgraded Performance Cabling type is outdated and no longer adequate Copper is viewed as a throw away medium Over 50% of all cabling sold is used to replace existing cabling Cat 3 replaced coax, Cat 5 replaced Cat 3, Cat 6 replacing Cat 5 The infrastructure is constructed for replacement

15 Why not Category 7 Western Europe Customers select Fiber over Category % Fiber 0.9% Cat % 1.0% Fiber Cat 7 Cat % Cat % Cat 7 is 0.0% in the US and only 0.3 % of the World Market Cat 5e Cat 5e 69.0% 63.1% Cat 5 4.9% Cat 5 3.0% BSRIA (Western Europe)

16 10GBASE-T Cat 6 compared to Cat db A B Cat 6 Attn Cat 6 Xtalk Cat 5 Attn Cat 5 Xtalk Frequency 62.5 MHz MHz How much additional cancellation is required in going from 1000BASE-T to 10GBASE-T A - B Extrapolating Cat 6 and Cat 5 limits to MHz

17 Additional cancellation Cat 5 Equal Level NEXT 46.2 For Category 5 at MHz more signal is returned than is transmitted down the cable Equal Level Return Loss 40.7 ELFEXT Cat Extrapolating Cat 6 and Cat 5 limits to MHz

18 Conclusion For Category 5 Cabling: None has been tested above 100MHz, Very little has been tested for Return Loss or ELFEXT, Only some has been tested to a requirement at all. Category 5e has become mixed in with Category 5 and is not significantly different in performance. The Forecast for Category 6 follows the same trend and time line as Category 5. 10GBASE-T should support what will be it s installed base when it reaches the market. The cabling will be replaced. Supporting legacy cabling makes the solution more difficult and in the past has not been successful.
