1 DATA CENTER SYMPOSIUM Dynamic Changes in Data Center Optic Transmissions & The Impact to Structured Fiber Cabling Rick Dallmann CABLExpress

2 Years of Experience CABLExpress is a manufacturer of custom built structured cabling solutions focused on high-end data center, network and SAN environments. RCDDs (Registered Communications Distribution Designer & DCDC); CDCD on staff Subject matter expert presenters at: AFCOM, BICSI, DatacenterDynamics (DCD) conferences and FOSE Expert structured connectivity data center design, spec and implementation according to TIA--A standards and IEEE. standards OEM and Authorized Solution Provider for Brocade, Arista, HP and others ISO : process and design certified qualification documented and verified by third party DATA CENTER SYMPOSIUM

3 Agenda Data Center Technology Speed Trends The Optics History Standards and Solutions Cabling Design Considerations and Challenges Standards Contradictions Questions DATA CENTER SYMPOSIUM

4 The Need for Speed: Just meeting the standards will render your infrastructure OBSOLETE. Rapid growth of server, network, and internet traffic Higher density requirements in the data center Low cost optical fiber Ethernet/SAN solutions Advances in technologies now allow the specification of the new //G physical layer with reduced lane count and complexity Lower cost results! // Gigabit Fibre Channel DATA CENTER SYMPOSIUM

5 Data Center Trends: Network Data Rates Rack Servers peak for G in while cloud servers peaked in. Cloud customers deploying G and above in DATA CENTER SYMPOSIUM

6 Data Center Trends: Network Data Rates Significant growth of G rack and /G blades DATA CENTER SYMPOSIUM

7 Next Generation Data Rates - Prepare Today, Avoid Upgrades Later IEEE.ba Standards OM glass support / gig speeds to meters OM glass support / gig speeds to meters IEEE.bm Standards (Released -) GBase-SR Transceiver speeds will jump from G per fiber to G Duplex LC: Bi-Di and universal G Ethernet IEEE.bs Standards (In Committee -) GBase-SR; increase to G per fiber Fibre Channel // Gigabit Fibre Channel DATA CENTER SYMPOSIUM

8 A Look Back in History LC Duplex Connector Historically, fiber connectors had discrete ferrules for each fiber. Now, fiber MT ferrules are standard in high density connectors. fiber MT ferrules DATA CENTER SYMPOSIUM

9 The Optics OFL (Overfilled Launch) LEDs, not lasers Power distributed over % of the fiber core PRE GIG Transceivers EMB (Effective Modal Bandwidth) VCSEL s Power distributed in a narrow region More accurate indication of performance in high-speed laserbased systems Different VCELS fill a different set of modes in each fiber, which can affect pulse spreading.
