  7. The Catch… • Network now managing waves not bits • The core optical network has evolved from Digital to Analog • Forces compromise between… • lower network cost (minimize OEOs)… • or number of markets served (OEO access) • Complexity remains for network managers: • Complexity of planning & deployment • Complex engineering, compensation and adjustment • No sub-l access to digital data • Limited add/drop, multiplexing or grooming • No digital performance monitoring or diagnostics Page

  8. 100 Gb/s Transmit 100 Gb/s Receive Infinera’s Photonic Integrated Circuit (PIC) Innovation 100Gb/s Transmit 100Gb/s Receive Page

  9. Infinera Differentiators • Photonic Integrated Circuit-Eased Benefits • Higher Reliability • Faster Scalability • Faster Install and Turn-up • Savings in Spares, Space, and Power • Digital Optical Networks-Enabled Benefits • Digital, Solid-State Add/Drop • Faster Time-to-Service • Forecast Tolerance • Consolidated Architectures Page

  10. Add/drop 10G, 2.5G, or GigE using hot-pluggable TAM cards All-Digital Implemented in solid state, e.g. silicon No MEMS, tunable filters, or other optical devices involved Completely independent from optical line Hitless No need to consider in span designs One TAM can drop traffic bound for different destinations Digital Networking Advantages:Infinera: Simple, Fast, Digital Add/Drop 0% 100% Percent Add/Drop 400 Gb/s 20 Gb/s 60 Gb/s 0 Gb/s Page

  11. Digital Networking Advantages:Forecast Tolerance • The forecasting challenge: • Predict the right amount of bandwidth… • The right service interfaces… • To the right locations… • At the right time • Infinera supports • 100Gb/s line side blocks of bandwidth • Interchangeable Tributary Adapter Modules • Add/Drop any service to any location on any port • Ultimate flexibility and forecast margin Page

  12. Summary: Photonic Integration Enables Digital Optical Networking • Fundamentally lower cost and steeper cost curve • Increased revenue potential with Add/Drop Anywhere • Simpler Network Architectures • Simpler Operations and Engineering Digital OpticalNetworking Page
