  5. Classifying Next-Gen Network Developments Broadband Venture Seminar Core Network Local Access Sep 7, 2001 Page 5

  6. Drivers for Next Generation NetworksLocal Access Networks Broadband Venture Seminar • More Raw and Symmetric Bandwidth • Up to 10 times the interactive bandwidth per user. • Fiber-deeper architectures, reducing node size down to 50 homes or less • Improved Network Availability- (smaller failure groups) • Fewer active elements in the field • Improved quality and lower maintenance costs Sep 7, 2001 Page 6

  7. Drivers for Next Generation NetworksLocal Access Networks Broadband Venture Seminar • Network cost savings • Combining equipment in headend and in the home to deliver multiple services • Continued decline in costs of deep fiber solutions • A recent study (Finisar) showed the cost of optical transmitters dropped 80% in the 5 years Sep 7, 2001 Page 7

  8. The End Result Broadband Venture Seminar • Powerful multimedia networks that are capable of handling high-volume interactive services • Alleviate potential network bottlenecks and improve network performance while delivering new advanced services • Unconstrained managed bandwidth everywhere will accelerate the creation and integration of next-generation IP services Sep 7, 2001 Page 8

  9. Broadband Venture Seminar Next Generation Local Access Networks • Traditional Cable “tree and branch” network • Hybrid Fiber/Coax Cable network • Switched GigE over Cable • Fiber - to - the – Curb - (FTTC) • Passive Optical Network Sep 7, 2001 Page 9

  12. HFC Architecture Broadband Venture Seminar Coax Fiber node area Fiber optic cable Sep 7, 2001 Page 12

  13. Broadband Deployment Broadband Venture Seminar 1984 - 2010 • Corporate America used Broadband for factory automation (GM, Ford,etc) • U.S. government used Broadband for facility-wide network (Rock Island Arsenal in IL) • Universities used Broadband for campus-wide networks (Emory University, University of Michigan) • Cable operators empowered the consumers (all over the U.S., 400 sites were tried) • Millions are using Broadband technology worldwide • Estimated 100 Million will use Broadband technology worldwide 1984 1988 1991 1995 2001 2010 Sep 7, 2001 Page 13

  14. HFC and FTTB Coexist Today Broadband Venture Seminar NODE HE NODE HFC OLT GbE FTTx Key Questions: • Merge these two over Cable HFC networks Sep 7, 2001 Page 14

  15. Exciting New Methods for Data over Cable Broadband Venture Seminar • Use spectrum above 860 MHz for 100 Mbps / 1 Gbps • Coexists with existing services below 860 MHz • Brings huge amount of bandwidth to bear for home and business use • Switched Ethernet, ubiquitous and low cost Sep 7, 2001 Page 15

  16. Fiber-to-the-Curb (FTTC) Broadband Venture Seminar Dedicated capacity to the home of business Coax and/or Cat5 wiring to homes Headend + Optical node Sep 7, 2001 Page 17

  17. Network Migration: HFC to FTTx Broadband Venture Seminar FTTB PON Headend OLT switch FTTC PON & HFC switch NODE NODE HFC Dedicated GbE wavelengths enable high-bandwidth FTTB Sep 7, 2001 Page 18

  18. Passive Optical Network(PON) Broadband Venture Seminar Optical Network Termination (ONT) Optical Line Termination (OLT) Optical splitter Sep 7, 2001 Page 20

  19. Summary Broadband Venture Seminar • The broadband access network must serve both residential and business customers • HFC is becoming more flexible and reliable • Scaleable bandwidth via DWDM • More passive via DWDM, GbE return and RF innovations • FTTx / GbE will co-exist with HFC to serve higher bandwidth needs • WDM technology provides scalability, reliability and compatibility with HFC • Networks leveraging both switched and passive deep fiber architectures Sep 7, 2001 Page 21
