3 Standards Today are Focused on High Bandwidth Applications and Supporting Media TIA TSB-172 floated specs for higher bandwidth 50µm fiber in 2007 TIA s OM4 standard d published September 2009 TIA 492AAAD Fibre Channel specifies OM4 in FC-PI5 draft that defines 16GFC 3rd ballot specifies OM4 to 150 m FC-PI5 draft also specifies OM4 for 8GFC and 4GFC Very limited loss budget allowed IEEE included OM4 for 40GbE & 100GbE Approved June 2010 OM3 to 100 m with 1.5 db connection loss allocation OM4 to 150 m with 1.0 db connection loss allocation Pre-standard d 550 meter fiber may or may not be compliant

4 International Standards are also Focused on High Data Rate Applications IEC OM4 standard approved April 2010, publication expected soon IEC ed. 4 specs harmonized with TIA standard CENELEC EN Series will be updated late this year with Class E A and FA with OM4 with LC as the standard fiber interface CENELEC EN contains a recommendation to use a polarity method that matches TIA Method B Allows alternative approaches to those described in B to B Greater number of component configurations may be required e.g. different designs of transition assembly or patch cord at each end

5 100G Multimode (MM) has great value over Singlemode (SM) Transceivers MM 100G SNAP Watts SM CFP (double XENPAK) Diagram from HSSG presentation cole_01_0107 (Finisar) Power dissipation from jewell_ 01_ 1106, pepeljgoski_01_0108, cole_01_0107, traverso_01_ Watts SM solution may cost > 10 times MM OM4 should cover > 95+ % of DC applications Power dissipation will be much higher for SM given need for: 10G electrical to 25G optical lane rate conversion Thermo-electric coolers to stabilize WDM wavelengths Edge-emitter bias levels 5-7x 850nm VCSEL levels This is reflected in the heat-sink size of the SM device SM ports consume line cards and chassis slots much faster than MM ports. Drives a significant SM cost disadvantage in Data Centers.
