Global Communication Network Submarine Cables… World’s Most Strategic Network Links

Global network availability must be ensured

Minimize wet and dry plant network demarcation

Single seamless network that spans planet earth

The New Global Network… erasing demarcation

points between submarine and terrestrial networks


Global Bandwidth Supply & Demand Demand Increasing… Prices Decreasing

Significant increases in demand

International prices are declining

How can providers differentiate?

Reference: 1Q2011 Global Bandwidth Forecast, 2011 (TeleGeography)

Reference: Median Trans-Pacific 10 Gbps Wavelength Prices, Q2 2010-Q2 2011 (TeleGeography)


Increasing Bandwidth Demands Cost-Effective Coherent-Based Capacity Upgrades

40G/100G coherent channel upgrades

Existing wet plants remains untouched

Far less expensive than laying new cables

Lowering the cost per transported bit


Undersea Cable Protection Challenges Unique Operating Environment

Undersea cables laid along seismically active and

heavily fished/trawled routes

Multiple terrestrial networks funneled through same

Cable Landing Station thus amplifying any outages

National economy/security affected by outages


Differentiation via Network Restoration Intelligence Customized Service Level Agreements

Traditional Linear/Ring Based Protection

Inability to survive more than 2 simultaneous failures

Minimal service protection differentiation

Intelligent Mesh Network Protection

Ability to survive multiple simultaneous failures

Intelligence enables customized protection offerings


Differentiated Restoration Offerings Attracting and Retaining New Customers

Traditional (50ms) Protection

No Protection

The New Global Network Seamless Networking Spanning Wet & Dry Plants

Erasing traditional terrestrial/submarine demarcation for truly resilient global networks


Summary Submarine Network Intelligence… Key Enabler

Global intercontinental bandwidth

demand continues to increase

Intelligent network protection will

enable improved network resilience

Cost-effective capacity upgrades

over existing/new undersea cables

The New Global Network… the whole

is greater than the sum of its parts
