Data Center (DC) Growth Fueled by CDN and Cloud
• Total DC traffic will see 33% CAGR growth between 2010-2015
– Cloud DC traffic will see 66% CAGR growth between 2010 and 2015
• Business cloud traffic will account for 19% business DC traffic by 2015
• Consumer cloud traffic will account for 37% consumer DC traffic by 2015

What are the Growth Implications for
Transpacific?
• By 2015, Internet traffic in Asia Pacific will generate 4 billion DVDs’ worth of
traffic, or 15.6 exabytes per month. (1)
• Average internet growth rates of 35% CAGR in region (1)
• South East Asia demand to US > 75% CAGR (2)
• Mobile data traffic >100% CAGR(2)
• Data centers growth across S.E. Asia

Growth
2000
2015
• Using these growth rates, we expect 6.4 Tb/s per FP will be required to meet
the demand for new systems installed between now and 2015!

Why Build Now?
• Internet Capacity Growth
• Data Centers
• Limited upgrade opportunities for existing systems
– 100 Gb/s cables require coherent technologies
• Wet Plant Technology is ready for the Tb/s
capacity needs today

Design Considerations: Technology
• 100 Gb/s High Capacity Trans-Pacific cannot be
achieved without moving to Coherent Technology
– Change in paradigm in system architecture –
transceivers, fiber maps
Future proofed wet path available today

Designed to meet critical
Customer needs
• Enable immediate deployment of coherent
detection
• Leverage current fiber mapping techniques
to extend the system reach beyond 3000 km
• Using coherent optimized path for future

Conclusion
• 100G is becoming the unit of transport
– Evolving network services require 100G connectivity
• Multi 10 Tb/s volume projections:
– Projected Trans-Pac growth calls for new multi-terabit
cables which cannot be met by upgrades of existing
cables
• Optimize wet plant design for investment
– Wet plant design and implementation are the most
significant pieces of the total investment
• Investment analysis favors 100Gb/s solutions on the wet path
