1 Nexans Cabling Solutions Easy and reliable migration from 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 Server to Switch links  need 40 Gig from 2016, 100 Gig 2019  majority of server links under 55 m Fibre Rich Copper Rich

4 Singlemode or multimode?

5 Parallel Optics for 40G ElectronicsOpticalElectronics 40G Relaxed specs for transceivers ( 0.25nm to 0.65 nm for 40G) Reduced distances MPO defined as connector in standard Standard IEEE 802.3ba approved in August G

6 Parallel Optics for 100G  100GBASE-SR10 (approved) 20 fibres  100GBASE-SR4 (in development) 8 fibres Approval expected mid of 2014 Distance being proposed: 100 m with OM4  MPO connectivity

7 Extended distances for 40G  Approved 40GBASE-SR4 standard with 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+

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

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

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  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 Key upKey downPair flip

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 LC patch cords OM3 or OM4 MPO cassettes LC couplers Switch 10G Server 10G

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

18 Summary  MPO is the F/O standard for 40G and 100G  The LANmark-OF MPO/LC-Cassettes allow an easy migration from 10G (with LC) up to 40/100G (MPO)  The polarity method used from nexans is designed for easy patchcord handling  The MTP connectivity used from Nexans ensures higher quality

19 Only one central port needed for four or eight users. Benefits of fibre cabling in 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

20 Structured cabling 2 different approaches Structured cabling (FTTO based)Structured cabling (traditional) No length restrictions
