Presentazione Futurology 10-40-100 GBEthernet tratta dal seminario internazionale Helping you to build a better networks conclusosi lo scorso luglio a LISBONA Portogallo
65. 40GBASE-T = 2GHz Cu cabling? System characteristics Shannon S/N @ 2GHz > 18dB IL/NEXT IL/RL PSD/Background noise NB: There is no current work in IEEE on twisted pair cabling for 40G IEC 61076-3-105 connector

69. Cu Cable – Data Centres (source: BSRIA) Installed Cu Cabling 1000BASE-T 10GBASE-T Outlets (millions) Source: BSRIA 2007
70. Technology forecast for the growth of Class EA cablingLogistic model : “New systems replace older ones because they are better suited to the environment” 50% share by 2015 2009
71. Forecasts for Cu cabling BR forecast Source: BSRIA 2009 10G cabling grows significant share from 2009
72. 10Gbps on FO * max channel lengths are advised assuming a connectivity insertion loss of 1.5dB Link margins are lower for 10G technologies
74. Forecasts for Optical cabling (LAN) BR forecast Source: BSRIA 2009 Enhanced MMF continues to grows strongly
75. Review Trends Faster speeds & higher data rates Switches will quickly adopt the new higher speeds 40GbE speeds will be in servers by 2011, 100GbE by 2018 Technology 10Gbps technology is established 40G & 100G devices will appear in 2010 FCoE, Data Centre Ethernet 40GbE on Cu, if developed, ≈2GHz cabling Implications to Cabling Class EA Cu cabling will grow OM3 & OM4 fibre will grow Cabling should be designed to be ready for 40G
