Agenda
• Historical aspects and trends relating to the 40/100G standard
• Trends toward increased fibre content and higher speeds in the DCs
• Review 40/100G standard for fibre
• Corning’s solution for 10G to 40G to 100G migration
– EDGE

1Gbps Ratified
10Gbps Ratified
40/100Gbps Ratified
• Recent history suggests that standards ratification and infrastructure cabling lead actual port sales by ~3 years

Data Center Environment
• Higher speeds (>10G)
• Higher density• Higher reliability• Lower capex • Lower opex
2010 Infonetics Market Analysis predicts increase in fibre in the DC:• 57% of ports are fibre in 2010• 73% of ports will be fibre in 2014

Ethernet 40/100G
• IEEE 802.3ba approved motions
– 40 and 100G– At least 100 m on OM3 multimode fibre– At least 150 m on OM4 multimode fibre– At least 10 km on single-mode fibre– At least 40 km on single-mode fibre (100G only)– At least 7 m on copper (twinax) cable assembly
• Intra-DC remains MM fibre; end-users and planners must re-think fibre infrastructure – 2-fibres per port (10G) – 12-fibres per port (40G) – 24-fibres per port (100G)

Summary
• Data Centres built for the future will be predominantly fibre:
– MTP connectivity / Parallel optics for high speed
– 40 and 100G are defined exclusively on fibre for distances outside
the cabinet
• The Corning EDGE Solution offers:
– Highest fibre port density with practical fibre access
– Use of ClearCurve® bend-optimised fibres (MM and SM)
– Migration from 10 to 40 to 100G maintaining same trunk cables
– Patch panel options in, above and below the rack
