Drivers for Next Generation Networks
Local Access Networks
• 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

Drivers for Next Generation Networks
Local Access Networks
• 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

The End Result
• 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

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

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

Exciting New Methods for Data over Cable
• 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

Summary
• 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
