Big Themes In Network EvolutionSurvivors Of The Valley Of Death
Big Themes In Network EvolutionSurvivors Of The Valley Of Death
Theme• Electrical To Optical• Circuit To Packet• Overlays to Shared Multi-Service• Narrowband To Broadband• Static Pt-Pt to Agile/Dynamic• Transport / Switching Integration• Manual To Automated• Rings To Mesh (in IOF, LH)• “Embedded Base Optimization”
– Networks Will Be Added To, Not Replaced, Due To Economic Realities
Drivers – Largely Non-Technical• Basic Carrier Viability
– Capex Reductions– Dramatic Opex Reduction
• “Triple Play” V/D/V Bundles• Changing Traffic Patterns
– Larger pipes– More data– Decreasing Revenue/bit– More Churn
• “All Distance Telecom”• Next Gen Content
Continued Innovation And Investment Needed At OpticalComponent, Systems, and Software Layers

Zooming In - Today’s Metro/IOF COZooming In - Today’s Metro/IOF COBased on Stacked ADM/MSPPs and DS-3 InterconnectionsBased on Stacked ADM/MSPPs and DS-3 Interconnections
• DS3 is the most common CO currency today, and the top selling MSPP card
• Craft-intensive architecture based on coax and DSX panels
• Inefficient manual cross-connect process
• Multiple points of failure
• High space and power requirements
• High Capex and Opex penalties

• Continue to spend on non-optimized network elements
• Inefficient manual cross-connect process
• Increased points of failure
• Greater space and power consumption
• Result• longer spans > more
repeaters• facility exhaust from

SummarySummary
• Industry Took An Abrupt Pause After 3 Years Of Irrational Exuberance, But Future Of Optical Networking Remains Vibrant
• Traffic Growth Drivers Have Slowed, But Bright Spots Remain– Total US High Speed Data Subs Grew 45% to 18.3m and 23% of Homes in 02
with Cable at 11.5m, DSL at 6.5m (Lehman Brothers 3-14-03)• Bandwidth-Intensive Emerging Services Such as Personal Video
Recorder, Pay-Per-View, HDTV, High Quality Audio are Happening• Major Opportunities Remain At All Levels Of Optical Foodchain
– Systems: MCAS, DWDM/ROADM, Ethernet Metro Access,…– Components: Metro EDFA, Tunable everything, next gen packaging – Software: GMPLS, Wavelength Services,…
• Key Growth Drivers For Next Optical Wave Are Economic, Not Technical– E.g. Business Value of Multi-service MCAS With Intelligent Control Plane Is
Redefining How Local Exchange Networks Are Built, Operated
