  1. Easy and reliable migrationfrom fast to faster to100G

  2. Bandwidth trends in data centres

  3. Cabling trends in data centres Switch to Switch links • early market for 100 Gig Ethernet • 100m links will cover all needs Fibre Rich Server to Switch links • need 40 Gig from 2016, 100 Gig 2019 • majority of server links under 55m Copper Rich

  4. Singlemode or multimode?

  5. Parallel Optics for 40G 40G Electronics Optical Electronics 40G 10G 10G 10G 40G 40G 10G 10G 10G 10G 10G • Relaxed specsfortransceivers (0.25nm to 0.65 nm for 40G) • Reduceddistances • MPO defined as connector in standard • Standard IEEE 802.3ba approved in August 2010

  6. Parallel Optics for 100G • 100GBASE-SR10 (approved) • 20 fibres • 100GBASE-SR4 (in development) • 8 fibres • Approvalexpectedmid of 2014 • Distancebeingproposed: 100 m with OM4 • MPO connectivity

  7. Extended distances for 40G • Approved 40GBASE-SR4 standardwith 2 connector model • 100m for OM3 • 150 m with OM4 and low loss • NCS at DCCC: 600 m with 9 MTP connectors • Cisco and others start to guarantee 400m over OM4

  8. Changes in connectivity and transceivers Duplex LC  MTP SFP+  QSFP+

  9. Plug&Play Concept LC Adaptors and Connectors Plug&Play Module MTP Connector and Adaptor MTP-MTP Pre-Term

  10. MTP implementation for 10G Female-Female Pre-Term MTP module Same duplex LC-LC patch cord both sides

  11. Migration to 40G/100G Female-Female Pre-Term Female-Female Pre-Term Key up/ Key Down adaptor Key up/ Key Up adaptor Same low loss male-female patch cord both sides

  12. MTP Connector and Adaptor • Alignment of fibre with guiding pins • Female connector: Pre-Term • Male connector: Module • Key on connector and adaptor • Maintain polarity • Key up/key down adaptor

  13. Polarity for 10G and 40G/100G Key up Pair flip Key down • Polarity method for 10G • Method defined in standards: method C • Polarity for 40G/100G • Not defined in standards, supplier specific • 2 types of patch cords because of male/female MPO • Nexans use 2 types of interconnection plates • Easy to install, recognise and maintain

  14. Port count during upgrade to 40G • 10 G with MTP modules • 6 x 10G ports = 60 G capacity • Total fibres for 6 ports: 12 • 40 G with MTP connectors • 6 port x 40G ports = 240 G capacity • Total fibres for 6 ports: 72 • Port count per rack grows over time

  15. Reliability = Cleaning of MTP connectors Dry cloth cleaner made from antistatic resins Designed to clean single fibre adaptors: stand alone or in an adaptor Cassette Cleaner for male MTP connectors

  16. Data Centre migration path to 40/100G for fibre Switch10G LC patch cords OM3 or OM4 MPO cassettes LC couplers Server 10G

  17. Data Centre migration path to 40/100G for fibre Switch40G MPO adapter plate MPO patch cords OM3 or OM4 Easy upgrade Easy installation Long usable life span Minimize downtime Low cost of ownership Server 40G

  18. Summary • MPO isthe F/O standardfor 40G and 100G • The LANmark-OF MPO/LC-Cassettesallow an easy migrationfrom 10G (with LC) upto 40/100G (MPO) • The polaritymethodusedfromnexansisdesignedfor easy patchcordhandling • The MTP connectivityusedfrom Nexans ensureshigherquality

  19. Benefits of fibre cablingin an office • Support long distances • No space restrictions for floor distributors and/or cable trays • Low refurbishment cost/less disruption • redundancy at user level • low loss and right sized POE+ at no additional cost Only one central port needed for four or eight users.

  20. Structured cabling2 different approaches Structured cabling (traditional) Structured cabling (FTTO based) No length restrictions
